437-004-0099

General Standards

(1) Miscellaneous.

(a) Conspicuously post warning signs, danger signs, warning flags, warning lights, or similar devices where hazards not otherwise adequately guarded warrant their use.

(b) Keep all safeguards or devices operating properly and fully effective at providing the protection originally intended.

(c) Erect protective barriers or suitable guards when covers over openings are removed or excavations made in places accessible to workers or vehicles.

(d) Do not allow the use of intoxicating liquor or drugs on the job. Do not allow anyone to work with impaired ability to work safely.

(e) Do not allow horseplay, scuffling, practical jokes or any other similar activity.

(2) Supervision and competency.

(a) Require employees to demonstrate their ability to work safely.

(b) Provide enough supervision over employees to ensure and enforce compliance with safe operating procedures and practices.

NOTE: It is not the meaning of this rule to require a supervisor on every part of any operation, nor to prohibit workers from working alone.

(c) Take all reasonable means to require employees:

(A) To work and act in a safe and healthful manner;

(B) To work in compliance with all applicable safety and health rules;

(C) To use all means and methods, including but not limited to, ladders, scaffolds, guardrails, machine guards, safety belts and lifelines, necessary to work safely where employees are exposed to a hazard;

(D) Not to remove, displace, damage, destroy or carry off any safety device, guard, notice or warning provided for use in any employment or place of employment where safety and health rules require such use.

(d) Use a procedure, appropriate for the work, to check on the well-being of workers whose duties require them to work alone or in isolation. Instruct all workers about the procedure.

NOTE: A two-way system of signals, thoroughly understood by both parties or other form of two-way communication is acceptable. Motor noise is not acceptable as contact or as an indication of well-being.

(e) Employers must provide all health hazard control measures necessary to protect the employees' health from harmful or hazardous conditions and must maintain those control measures in good working order and assure their use.

(f) Employers must inform their employees about the known health hazards to which they are exposed, the measures taken for the prevention and control of those hazards, and the proper methods for using the control measures.

(3) Inspections. A competent person or persons must inspect every place of employment at least quarterly. OAR 437-004-0251 has other requirements related to these inspections.

(4) Investigations.

(a) The employer must investigate every work-related lost time injury. The object of the investigation is to determine how to prevent recurrence. OAR 437-004-0251 has other requirements related to these investigations.

NOTE: As mentioned above, “lost time injury” is the same as the ORS 656.005(7)(c) definition of “disabling compensable injury.” That is: an injury that entitles the worker to compensation for disability or death. To fall into this category the employee must miss three consecutive calendar days beginning with the day the worker first loses time or wages from work as a result of the compensable injury. This includes weekends and holidays when they might normally be off.

(b) At the request of authorized OR-OSHA representatives, you or your superintendents, supervisors and employees must furnish all evidence and names of known witnesses to an accident.

(c) Employees in charge of work are agents of the employer in the discharge of their authorized duties, and are always responsible for:

(A) The safe performance of the work under their supervision; and

(B) The safe conduct of the crew under their supervision; and

(C) The safety of all workers under their supervision.

(5) Extraordinary hazards. When conditions arise that cause unusual or extraordinary hazards to workers, take additional means and precautions to protect workers or to control the hazardous exposure. If you cannot make the operation reasonably safe, stop work while the abnormal conditions exist or until the work is safe.

(6) Signals and signal systems.

(a) Give control signals by only one person at a time.

(A) When given, make signals clear and distinct.

(B) The person receiving the signals must understand their meaning before taking action.

(b) Act immediately on emergency stop signals from whatever source.

(c) Do not throw any type of material that can produce injury, such as rocks, wooden or metal objects, etc., as a signal.

(d) Do not give signals for the movement of materials or equipment until all persons who might be in danger by the movement are in the clear.

Definitions

437-004-0100

Universal Definitions

(1) These definitions apply throughout Division 4, Agriculture, except that the definitions in Subdivision 4/W, adopted from 40 CFR 170, Worker Protection Standard, apply to the rules within that Subdivision.

(a) Accepted — Something is accepted if:

(A) A nationally recognized testing laboratory has inspected it and found it to conform to specified plans or to procedures of applicable codes; or

(B) It is verified by design, evaluation, or inspection by a registered professional engineer; or

(C) It is acknowledged by the authority having jurisdiction, the agency, office, or organization that is responsible for approving specific equipment, materials, installations, or procedures. (Examples of such authorities include the U.S. Department of Transportation, the U.S. Coast Guard, the Oregon Building Codes Division, and the Office of the State Fire Marshal.)

(b) Agricultural employer — means any person, corporation, association, or other legal entity who meets the definition of an employer in ORS 654.005(5) and who:

(A) Owns or operates an agricultural establishment; or

(B) Recruits and supervises employees who work for an agricultural establishment; or

(C) Is responsible for the management or condition of, or exercises direction and control over the production on, an agricultural establishment.

(c) Agricultural establishment — means a farm, ranch, nursery, greenhouse, or production facility that is a place of employment and is engaged in the activities described in Division 4/A, 437-004-0002 Scope.

(d) Approved — means acceptable for the purposes of rule compliance, under the following criteria:

(A) It is accepted, or certified, or listed, or labeled or otherwise determined to be safe by a nationally recognized testing laboratory; or

(B) If an installation or equipment is of a kind which no nationally recognized testing laboratory accepts, certifies, lists, labels, or determines to be safe, it has been inspected or tested by another authority having jurisdiction and found to be in compliance with the provisions of the applicable code; or

(C) Custom-made equipment or related installations that are designed and fabricated for a certain intended use by its manufacturer. The employer must keep and make available the test data that is used as the basis of this approval, for inspection.)

(e) Boiling point — The temperature at which the liquid form of a substance changes into a vapor, at a standard atmospheric pressure. The initial boiling point of a substance is determined according to test methods specified in Appendix B to Division 2/Z, 1910.1200, Hazard Communication Standard.

(f) CAS — is the Chemical Abstracts Service Registry Number, a unique numerical identifier assigned by the Chemical Abstracts Service to every chemical described in the open scientific literature.

(g) Capacity — is the maximum load or severity of service (determined by the manufacturer or a qualified engineer) that a tool, machine, equipment, structure, or material is expected to withstand without failure, deformation, separation or fracture.

(h) Certified — is something that:

(A) Was tested and found by a nationally recognized testing laboratory to meet recognized standards or to be safe for use in a specified manner, or

(B) Is of a kind whose production is periodically inspected by a nationally recognized testing laboratory, and

(C) Shows a label, tag, or other record of certification.

(i) Combustible — A substance or material that is able or likely to catch fire and burn.

(j) Combustible liquid — The “combustible liquid” classification is no longer used in Division 4 rules because it was eliminated by the globally harmonized classification and labeling system (GHS) adopted in OSHA’s Hazard Communication Standard. Any liquid with a flash point of 199.4°F (93 degrees C.) or less is considered to be one of the four categories of flammable liquids. (See “Flammable liquids,” below.)

NOTE: The term “combustible liquid” is still used by the National Fire Protection Association (NFPA) system of classification and by the Oregon State Fire Marshal to classify liquids that will burn but do not ignite as easily as flammable liquids. The NFPA system defines some chemicals as “combustible liquids” that would be included as a category of “flammable liquid” in the OSHA/GHS classification system. (See Appendix A to Subdivision 4/H, 437-004-0720 Flammable Liquids, for a comparison of the GHS and NFPA systems of classification of flammable/combustible liquids.)

(k) Competent person – is a person who, because of training and experience, can identify existing and predictable hazards in equipment, material, conditions or practices; and, who has the knowledge and authority to take corrective steps.

(l) Explosive — something capable of causing damage to the surroundings by chemical reaction. Explosives are defined in Appendix B to 1910.1200 – Physical Hazard Criteria at B.1 EXPLOSIVES.

(m) Farming — Is the production of agricultural field crops, tree crops; horticultural specialties, greenhouse crops; and the production of livestock and animal specialties. Farming includes farm labor and management services; agricultural services and support activities (such as soil preparation; crop cultivation, protection, and harvesting;) and, the basic preparation of the crop or commodity for market. The farming production process is typically completed at the “farm gate” – that is, at the point of first sale or price determination.

NOTE: Throughout this division, the term “farming,” “agriculture,” “production agriculture,” and “agricultural operations” are synonymous.

(n) Flammable — Capable of being easily ignited, burning intensely, or having a rapid rate of flame spread. Flammable substances are defined in Appendix B to 1910.1200 — Physical Hazard Criteria at B.2 FLAMMABLE GASES, B.3 FLAMMABLE AEROSOLS, B.6 FLAMMABLE LIQUIDS, and B.7 FLAMMABLE SOLIDS.

(o) Flammable liquids — are liquids having a flash point at or below 199.4 degrees F. (93 degrees C.) As defined in the globally harmonized system of classification and labeling (GHS) adopted in OSHA’s Hazard Communication Standard, flammable liquids are divided into four categories as follows:

(A) Category 1 includes liquids that have a flashpoint below 73.4 degrees F. (23 degrees C.) and have a boiling point at or below 95 degrees F. (35 degrees C.)

(B) Category 2 includes liquids that have a flashpoint below 73.4 degrees F. (23 degrees C.) and have a boiling point above 95 degrees F. (35 degrees C.)

(C) Category 3 includes liquids that have a flashpoint in a temperature range from at or above 73.4 degrees F. (23 degrees C.) to at or below 140 degrees F. (60 degrees C.)

(D) Category 4 includes liquids that have a flashpoint in a temperature range from above 140 degrees F. (60 degrees C.) to at or below 199.4 degrees F. (93 degrees C.)

NOTE: Examples of some common flammable liquids are:

Category 1: Diethyl ether (solvent sometimes used in starting fluid).

Category 2: Gasoline (Benzene, Ethanol).

Category 3: Kerosene, Stoddard Solvent.

Category 4: Diesel fuel, Naphthalene.

(p) Flashpoint — is the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid, as determined by specific testing methods. These test methods are specified in Appendix B to Division 2/Z, 1910.1200, Hazard Communication Standard.

(q) Hazardous Chemical — is any chemical which is classified, under the requirements of the Hazard Communication Standard, as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, pyrophoric gas, or hazard not otherwise classified.

NOTE: See Division 2/Z, 1910.1200 Hazard Communication Standard, for more information.

(r) Ignition source — the origin of something that results in a fire or an explosion. Examples include open flames; smoking; cutting and welding; hot surfaces and radiant heat; frictional heat; static, electrical, and mechanical sparks; chemical and physical-chemical reactions; spontaneous ignition; and lightning.

(s) Labeled — Something is labeled if:

(A) It has an attached label, symbol, or other identifying mark of a nationally recognized testing laboratory that makes periodic inspections of the production of such equipment; or

(B) The attached information indicates compliance with nationally recognized standards or tests to determine safe use in a specified manner.

(t) Listed — is something mentioned in a list that:

(A) Is published by a nationally recognized laboratory that makes periodic inspection of the production of such equipment, and

(B) States such equipment meets nationally recognized standards or was tested and found safe for use in a specified manner.

(u) Nationally Recognized Testing Laboratory — (NRTL) is defined in 1910.7 Definition and Requirements for a Nationally Recognized Testing Laboratory and OAR 437-002-0007 Oregon Rule on Testing and Certification Program. (Examples of organizations in this category are Factory Mutual Engineering Corporation, and Underwriters’ Laboratories.)

(v) Place of employment — is every place (fixed, movable or moving) where an employee works or is intended to work. It includes every place where (either temporarily or permanently) there is any activity related to an employer's business, including a labor camp.

NOTE: “Place of employment” does not include a place where the only employment involves nonsubject workers employed in or about a private home; or a farm where only the farm’s family members are employed.

(w) Qualified person — is a person who has a recognized degree, certification, professional standing, knowledge, training or experience; and has successfully demonstrated the ability to perform the work, or solve or resolve problems relating to the work, subject matter, or project.

(x) Reasonable means — is what a prudent person, familiar with the circumstances of the industry would do to work in a safe and healthful manner.

(y) Safeguard — is any form of safety device or equipment; personal protective equipment; guard or barricade; warning device, sign, or method; or a process prescribed or adopted for the protection of an employee.

(z) Substantial — means constructed with sufficient strength or installed to provide ample support to withstand loads to which the structure or device may be subjected.

(aa) Worker — is identical in every respect to “employee” as defined in ORS 654.005(4) including:

(A) Any individual, including a minor, whether lawfully or unlawfully employed, who engages to furnish services for a remuneration, financial or otherwise, subject to the direction and control of an employer; and

(B) Any individual who is provided with workers’ compensation coverage as a subject worker pursuant to ORS chapter 656, whether by operation of law or by election.

Division 4/C, Safety Awareness

437-004-0240

Safety Orientation for Seasonal Workers

Definitions:

Hand-labor operations, (as defined in OAR 437-004-1110(3) and reprinted here for ease of the reader) means agricultural activities or agricultural operations performed by hand or with hand tools, including:

(a) Hand-cultivation, hand-weeding, hand-planting, and hand-harvesting of vegetables, nuts, fruits, seedlings, or other crops (including mushrooms);

(b) Hand packing or sorting, whether done on the ground, on a moving machine, or in a temporary packing shed in the field.

Seasonal workers are employed in a job tied to a certain time of year by an event or pattern and for not more than 10 months in a calendar year.

NOTE: The following are only minimum requirements. Other parts of the agriculture standard require training for certain types of work in addition to these general orientation requirements.

(1) Application: This applies to agricultural employers with seasonal workers.

(2) Basic Safety Awareness Requirements.

(a) You must provide seasonal workers with at least the following information:

At their orientation meeting before beginning work for the first time, and;

When work conditions or locations change in a way that could reasonably affect their safety or health.

(A) Safety and health rules for their work.

(B) Procedures for workers to contact supervisors or managers in case of accident, illness, or problems related to safety or health.

(C) Procedures for treating injured or sick workers and for summoning emergency assistance.

(D) The location of posted safety and health information.

(b) If you have employees with language barriers, you must communicate safety awareness information in a manner that workers can understand. Include content that is either translated into the language used to hire and supervise these employees or that is otherwise effectively conveyed, such as through visual media.

NOTES: Division 4/Z, Hazard Communication, OAR 437-004-9800(7)(d), requires employers to give a copy of the Oregon OSHA’s Safe Practices When Working Around Hazardous Agricultural Chemicals (#1951) to every employee. This publication provides an outline of the information that agricultural employers must provide during the initial training for workers under both the hazard communication rules and the pesticide worker protection standard (WPS) as covered in Division 4/W, 170.130(c). Contact Oregon OSHA for copies of this publication and information about available language formats.

You must provide the initial WPS training if pesticide products labeled with “agricultural use requirements” have been used at the place of employment during the 30 days prior to the worker’s first day of employment or will be used during the worker’s period of employment. Additional WPS training requirements apply on the sixth day of employment, and in other work situations that fall under the definition of “pesticide handler.” See Division 4/W for these additional training requirements.

For seasonal workers doing hand-labor operations only, you must provide all of the following to meet the initial training requirements under the WPS, this safety awareness orientation rule, and the hazard communication rule.

• The training outlined in Safe Practices When Working Around Hazardous Agricultural Chemicals publication.

• The basic safety awareness requirements information in OAR 437-004-0240.

• Access to material safety data sheet information for the hazardous chemicals to which they reasonably may be exposed.

Safety Committees

437-004-0251

Safety Committees and Safety Meetings

Definitions:

Management — includes all supervisors and persons who regularly exercise direction and control over workers.

Workers — for the purposes of determining the need for a safety committee, include both full and part-time employees.

Purpose. The purpose of safety committees and safety meetings is to bring workers and management together in a non-adversarial, cooperative effort to promote safety and health in each workplace. A safety committee assists the employer by establishing procedures, performing inspections, evaluating safety and health programs, and recommending changes in workplace conditions and practices. By participating in safety meetings, workers and management work together to recognize hazards and to make safety and health improvements at the workplace.

(1) Application: This applies to agriculture employers with workers other than seasonal workers covered in OAR 437-004-0240.

(2) General Requirements.

(a) You must either have an effective safety committee or hold effective safety meetings. (See Table 1.)

(b) If you have employees with language barriers, you must communicate safety awareness information in a manner that workers can understand. Include content that is either translated into the language used to hire and supervise these employees or that is otherwise effectively conveyed, such as through visual media.

(c) If you are a labor contractor, you must have a committee or meetings based on the number of employees that you direct and control.

NOTE: Nothing in these rules prevents you from having seasonal workers attend safety meetings.

(o) Through ladder. A ladder from which a person getting off at the top must step through to reach the landing.

(p) Well. A permanent complete enclosure around a fixed ladder, that is attached to the walls of the well. Proper clearances for a well will give the climber the same protection as a cage.

(2) Design requirements. Design considerations: All ladders, appurtenances, and fastenings must meet these load requirements:

(a) The minimum design live load must be a single concentrated load of 200 pounds.

(b) Design consideration must include the number and position of additional concentrated live load units of 200 pounds each as determined from anticipated use.

(c) Consider the live loads caused by persons on the ladder to be concentrated at such points as will cause the maximum stress in the structural member being under evaluation.

(d) Use the weight of the ladder and attachments together with the live load when designing rails and fastenings.

(e) All wood parts of fixed ladders must meet the requirements of OAR 437-004-0340(3).

Noise Exposure

(1) You must have a noise monitoring program (see (3) below) when an employee’s exposure equals or is more than an 8-hour time-weighted average (TWA) of 85 decibels (dB).

NOTE: Most large or older farm machines and tractors, especially those without cabs, have the potential to produce more than 85 decibels of noise. Audiologists often say that if you have to shout or significantly raise your voice to talk with somebody 2 feet away, the noise is probably at the action level of 85 decibels.

(2) Noise classified as impulse or impact noise cannot be more than 140 dB peak sound pressure level.

NOTE: These noises are sudden and sharp and include such things as the firing of a weapon and sudden release of pressurized air.

(3) Noise Monitoring Employers must use a noise sampling strategy that determines which employees need to be part of a hearing conservation program. This sampling will also determine their need for hearing protection or when to consider engineering controls.

(a) Use a sound level meter or a dosimeter to do noise level surveys over an 8-hour period to get a time-weighted average. When the employees are mobile or there are significant changes in the sound level or impulse noise components, you must use representative personal sampling unless area samples produce equal results.

(b) Repeat the noise surveys when there is a change in production, process, equipment or controls that increases noise levels or exposures to or above the action level. Also repeat the surveys if the increase in noise may require additional noise reduction from hearing protectors already in use.

(c) Notify each monitored employee of the noise monitoring results if the exposure was at or above the 85 decibel TWA.

(d) The employer must give affected employees or their representatives the opportunity to observe the noise survey process.

WARNING: Employer responsibilities in this standard require special knowledge and equipment to be done successfully. In most cases it is advisable and in some cases mandatory to have these tests done by a professional. See OAR 437-004-0630(5)(c).

(4) Engineering Controls If the noise survey results are more than in Table 1 below, use administrative or engineering controls to reduce the noise, if feasible. If not feasible or if the engineering or administrative controls fail to reduce the noise to levels within Table 1 limits, provide appropriate training and enforce the use of hearing protection to reduce the noise to levels within the Table 1. [Table not included. See ED. NOTE.]

(a) You must provide all hearing protection equipment and devices without cost to the employee. Employees may voluntarily elect to use their own equipment but the employer is responsible to assure that it provides adequate protection.

(b) All hearing protection equipment and devices must be kept serviceable and clean according to the manufacturer’s recommendations or accepted audiological practices. Table 1 [Table not included. See ED. NOTE.]

(5) Hearing Conservation Program Establish and maintain an effective hearing conservation program for employees whose noise exposure equals or is more than an 8-hour TWA of 85 decibels, or an equivalent dose, before attenuation by hearing protectors. The program must include an audiometric (hearing) testing program, employee training and personal hearing protection.

(a) All parts of the hearing conservation program must be without charge to employees.

(b) You must tell the employees to avoid high levels of non-occupational noise exposure during the 14-hour period before any hearing test. Also, you must assure that the employee uses hearing protection or avoids noise exposure on the job for 14 hours before getting a baseline hearing test.

(c) Only a technician certified by the Council of Accreditation in Occupational Hearing Conservation, a licensed or certified audiologist, otolaryngologist or other physician may do a hearing test. Certified technicians must be responsible to an audiologist, otolaryngologist or physician.

NOTE: Audiograms must meet the requirements of OAR 437-002-1910.95, Appendix C, Audio- metric Measuring Instruments. The background noise in the test room must comply with OAR 437-002-1910.95, Appendix D, Audiometric Test Rooms. The audiometers used for the test and the methods must comply with the American National Standard Specifications for Audiometers, S3.6-1969. Oregon OSHA strongly suggests that employers hire a professional to provide services required by this standard.

(6) There are two types of hearing tests required by this standard.

(a) A baseline hearing test must be done within 6 months of the employees first exposure to noise at or above the action level. This test is the comparison base for future tests.

(b) After the baseline audiogram is done, each employee still exposed at or above the 8-hour TWA must have annual hearing tests. Compare the annual tests to the baseline tests to determine if there has been a standard threshold shift.

(c) The audiologist, otolaryngologist or physician evaluation of the audiogram may revise the baseline when the standard threshold shift in hearing revealed by the test is persistent or the hearing threshold shows an improvement over the baseline audiogram.

(7) For purposes of this standard a standard threshold shift of hearing compared to the baseline hearing test is called a standard threshold shift and is an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear. In Oregon there is no allowance from age correction charts for this calculation.

(8) Follow-Up The qualified person doing the hearing test will compare the results of the annual hearing test to the baseline audiogram to see if it is valid and if there has been a standard threshold shift change in hearing as in (7) above.

(a) The employer may retest to assure validity within 30 days and use that as the annual test.

(b) An audiologist, otolaryngologist or physician must review all problem audiograms to determine the need for more evaluation. This may include follow up as described below.

(c) The employer is responsible to pay for this evaluation.

(d) The employer must assure that the reviewing audiologist, otolaryngologist or physician has the following information:

(A) A copy of the requirements for hearing conservation in this section.

(B) The employees baseline and most recent audiogram.

(C) Measurements of the noise levels in the audiometric test room.

(D) Records of audiometer calibrations as required by this section.

(9) If an employee’s hearing test reveals a standard threshold shift, the employer must do (a) through (d) below unless the physician determines that the shift is not work-related or aggravated by work-related noise exposure.

(a) Fit employees with hearing protection, train them in its use and care. Require them to use it.

(b) Refit and retrain employees already using hearing protectors. Give them hearing protectors that offer more noise reduction.

(c) Refer the employee for a clinical audiological evaluation or an otological examination, as appropriate, if additional testing is necessary. Also refer the employee to the physician if the wearing of hearing protectors causes or aggravates a medical problem of the ear.

(d) Inform the employee of the need for an otological examination if a medical pathology of the ear could be unrelated to the use of hearing protectors.

(10) If future hearing tests show that the standard threshold shift of hearing is not persistent and the noise exposure is less than a 8-hour TWA of 90 decibels the employer must tell the employee of the new results and may end the required use of hearing protectors.

(11) Training All employees exposed at or above the 8-hour TWA of 85 decibels must receive initial and annual training. Update the training program if there are changes in the hearing protection or work processes. The training program must include:

(a) The effects of noise on hearing.

(b) The purpose of hearing protectors, the advantages, disadvantages and attenuation of various types and instructions on selection, fitting, use and care.

(c) The purpose of the hearing test and an explanation of the test procedures.

(12) Hearing Protection Hearing protection must be available at no cost to all employees exposed to an 8-hour TWA of 85 dB. Wearing of hearing protection that offers adequate noise reduction is mandatory for employees exposed at 90 dB TWA. In addition, if an employee has had a standard threshold shift, they must wear hearing protection at 85 decibels or more.

(a) The employer must ensure proper initial fitting of the hearing protectors, supervise the correct use of them, and provide training in the use and care of the hearing protectors.

(b) The employees must have the chance to select the hearing protectors from a variety of appropriate hearing protectors and the hearing protectors must reduce the noise to at least an 8-hour TWA of 90 decibels.

(c) When noise exposure increases enough that the hearing protectors may no longer give proper protection, reevaluate the adequacy of the protectors noise reduction. Pro- vide more effective hearing protection where necessary.

(13) Recordkeeping The employer must keep employees noise exposure records according to the Access to Employee Exposure and Medical Records standard OAR 437-004-0005. The records must be available to employees, former employees, representatives designated by the employee and Oregon OSHA. The test record must include:

(a) Name and job classification of the employee.

(b) Date of the audiogram.

(c) The examiner’s name.

(d) Date of the last acoustic or exhaustive calibration of the audiometer.

(e) Employees most recent noise exposure assessment.

(14) If you sell your business, give the buyer all records required by this section.

NOTE: The professional who does your audiometric work will supply most of the records required by this section.

Oxygen

(1) Scope. This applies to the installation of bulk oxygen systems on agricultural establishments.

(2) Bulk oxygen systems.

(a) Definition. A bulk oxygen system is an assembly of equipment, such as oxygen storage containers, pressure regulators, safety devices, vaporizers, manifolds, and interconnecting piping, with storage capacity more than 13,000 cubic feet of oxygen, Normal Temperature and Pressure (NTP), connected in service or ready for service, or more than 25,000 cubic feet of oxygen (NTP) including unconnected reserves on hand at the site. The bulk oxygen system ends where oxygen at service pressure first enters the supply line. The oxygen containers may be stationary or movable, and the oxygen may be gas or liquid.

(b) Location.

(A) General. Bulk oxygen storage systems must be above ground, outdoors or in a noncombustible building, adequately vented and used exclusively for oxygen storage. Locate containers and associated equipment so there is no exposure to electric power lines, flammable or combustible liquid lines, or flammable gas lines.

(B) Accessibility. Locate the system so that it is readily accessible to mobile supply equipment at ground level and to authorized personnel.

(C) Leakage. For liquid oxygen storage, provide noncombustible surfacing in the area where any leakage might fall during operation of the system and filling of the container. Asphalt or bituminous paving is combustible.

(D) Elevation. When locating bulk oxygen systems near above-ground flammable or combustible liquid storage that may be either indoors or outdoors, it is advisable to locate the system on ground higher than the flammable or combustible liquid storage.

(E) Dikes. When a bulk oxygen system must be lower than adjacent flammable or combustible liquid storage, there must be suitable means (such as diking, diversion curbs, or grading) to prevent accumulation of liquids under the bulk oxygen system.

(c) Distance between systems and exposures.

(A) The minimum distance from any bulk oxygen storage container to exposures, measured in the most direct line except as in (2)(c)(A)(v) and (vii) below, must be as follows:

Flammable and Combustible Liquids

(1) Definitions:

(a) Approved — See Universal Definitions in 4/B, OAR 437-004-0100.

(b) Closed container — A container sealed with a lid or other device that prevents the loss of liquid or vapor at ordinary temperatures.

(c) Combustible — A substance or material that is able or likely to catch fire and burn.

(d) Combustible liquids — See definition of “Flammable liquids” below.

NOTE: When Oregon OSHA revised the Hazard Communication Standard to align with the Globally Harmonized System (GHS) of classification and labeling of chemicals, the term “combustible liquid” was eliminated. However, the term is still used by the National Fire Protection Association (NFPA) and by the Oregon State Fire Marshal. The NFPA system classifies some chemicals as “combustible liquids” that OSHA classifies as “flammable liquids.”

(e) Explosive — something capable of causing damage to the surroundings by chemical reaction. Also, see Universal Definition in 4/B, OAR 437-004-0100.

(f) Flammable — something capable of being easily ignited, burning intensely, or having a rapid rate of flame spread. Also, see Universal Definitions in 4/B, OAR 437-004-0100.

(g) Flammable liquids — are liquids having a flash point at or below 199.4 degrees F. (93 degrees C.) As defined in the globally harmonized system of classification and labeling (GHS) adopted in OSHA’s Hazard Communication Standard, flammable liquids are divided into four categories as follows:

(A) Category 1 includes liquids that have a flashpoint below 73.4 degrees F. (23 degrees C.) and have a boiling point at or below 95 degrees F. (35 degrees C.)

(B) Category 2 includes liquids that have a flashpoint below 73.4 degrees F. (23 degrees C.) and have a boiling point above 95 degrees F. (35 degrees C.)

(C) Category 3 includes liquids that have a flashpoint in a temperature range from at or above 73.4 degrees F. (23 degrees C.) to at or below 140 degrees F. (60 degrees C.)

(D) Category 4 includes liquids that have a flashpoint in a temperature range from above 140 degrees F. (60 degrees C.) to at or below 199.4 degrees F. (93 degrees C.)

NOTES: See Appendix A to OAR 437-004-0720 Flammable Liquids for a comparison of the GHS/Hazard Communication classification system with the NFPA classification system. Examples of flammable liquids include: Category 1: Diethyl ether (solvent used in some starting fluids) Category 2: Gasoline, Benzene Category 3: Kerosene, Stoddard Solvent

Category 4: Diesel fuel

(h) Portable tank — A closed container with a liquid capacity more than 60 U.S. gallons (230 liters) and not intended for fixed installation.

(i) Safety can — An approved closed container, of not more than 5 gallons (20 liters) capacity, with a spring-closing lid and spout cover, and designed so that it will safely relieve internal pressure when subjected to fire.

(2) Storage and transporting.

(a) The storage of flammable liquids in containers with a capacity of 60 gallons (230 liters) or more must be in fixed or portable tanks. Such tanks must meet the material and design requirements in NFPA 30, Flammable and Combustible Liquids Code, 1996 edition.

NOTE: Tanks meeting the requirements of a more recent edition of the NFPA 30 code will also be considered to be in compliance with this rule.

(b) Storage of flammable liquids in containers of less than 60 gallons (230 liters) capacity must be in one of the following listed in Table H-1: [Table not included. See ED. NOTE.]

(c) Store flammable liquids in a manner that will not obstruct, impede, or limit use of exits, stairways, or areas normally used for safe exit routes.

(d) Flammable liquids transported in passenger-type vehicles (cars, trucks, buses, carry-alls, crew transporters, etc.) must be in safety cans, or approved containers used for petroleum fuels. Carry these containers outside the passenger compartment, secured in a ventilated area that prevents the accumulation of flammable or explosive vapors, and that protects against rupture in a collision.

(3) Tanks and containers.

(a) Clearly mark tanks and containers as required in the Hazard Communication Standard, OAR 437-004-9800(5) Labels and other Forms of Warning. Mark fill-risers and pumps or discharge devices with the name of the product they contain.

NOTE: Division 4/L, 437-004-1440 requires employers to post signs reading, “No Smoking or Open Flame” (or “FLAMMABLE — KEEP FIRE AWAY”) in areas used for fueling, and where flammable liquids are received, dispensed, used, or stored.

(b) Protect pumps, containers, tanks, and supports for tanks used for flammable liquids against collision damage.

(c) Mount aboveground tanks on supports that are strong and stable enough to safely support the load. Provide enough clearance to permit inspection and maintenance as well as clearance from the ground.

(4) Tanks elevated for gravity discharge.

(a) The gravity discharge outlet must have an approved hose with a self-closing valve at the discharge end.

(b) The bottom opening for gravity discharge must have a shut-off valve adjacent to the tank shell that can be closed manually. Underground tanks from which fuel flows under gravity must have a manual shut-off valve between the tank and the hose.

(5) Tanks with top openings only.

(a) Tanks with all openings in the top must have a firmly attached, approved pumping device and an approved hose.

(b) Do not use siphons and discharge devices requiring pressure in the container.

(c) There must be an effective anti-siphoning device in the pump discharge; tank plumbing must not permit fuel to siphon or flow from the tank when the pump is not operating, even though discharge nozzle valves or line valves are open.

(6) Dispensing and fueling.

(a) Maintain pumping devices or faucets used to dispense flammable liquids so they do not leak enough material to puddle or cause a fire hazard.

(b) Fuel tanks and pumps from which flammable liquids are dispensed must have an approved hose long enough to fill containers.

(A) Hoses must have a metal nozzle at the discharge end.

(B) Hoses must incorporate an effective electrical interconnect between the nozzle and the supply tank.

(c) Do not dispense flammable liquids into or from portable or stationary metal tanks or drums unless there is an effective electrical interconnect (bond) between the source and the receiving containers.

NOTES: The electrical interconnect may be made by assuring that the metal nozzle of the approved hose is in contact with the metal fill neck or bung of the receiving container during filling. Both portable metal and portable plastic containers should be placed on a grounded surface when filling.

(d) Shut off internal combustion engines, except diesel engines, while refueling.

(7) Handling and use of flammable liquids.

(a) Control leakage or the escape of flammable liquids and use measures to prevent accidental spills. If a spill occurs, promptly clean any soaked or contaminated areas.

NOTE: If you have a release or spill of any hazardous substance at your workplace and you expect your employees to help clean it up, other rules may apply: Division 4/Z, 437-004-9800, Hazard Communication Standard for Agricultural Employers. Division 4/H, 437-004-0950 Hazardous Waste Operations and Emergency Response.

(b) Use flammable liquids, including gasoline, only where there is no open flame or other source of ignition within 50 feet of the operation, or within the possible path of vapor travel.

NOTES: This rule does not prohibit the refueling of orchard heaters used outdoors while adjacent heaters are burning; or the field (outdoor) refueling of portable tools while other tools are in operation. Division 4/L, 437-004-1430 requires employers to forbid smoking, open flames, the use of spark-producing devices or tools, and other sources of fire or ignition in fueling areas; where fuel systems for internal combustion engines are serviced; and where flammable liquids are received, dispensed, used, or stored.

(c) Do not use flammable liquids, including gasoline, indoors as a solvent or for cleaning purposes unless there is adequate ventilation to keep the concentration of vapors in the atmosphere below 20 percent of its lower explosive limit (LEL).

NOTE: In addition to the hazards of fire and explosion, the potential health hazards from exposure to flammable liquids through skin contact or breathing the vapors should also be avoided.

(d) Keep flammable liquids, including gasoline, in closed containers when not in use.

(8) Heating devices that use flammable liquids.

NOTE: The Oregon State Mechanical Specialty Code and the Oregon Fire Code have standards for space-heating devices and associated equipment.

(a) Set heaters, when in use, on a stable, level base; or mount them as specified by the manufacturer.

(b) Heaters not suitable for use on wood floors must rest on heat insulating material of at least 1-inch concrete, or equivalent. The insulating material must extend beyond the heater 2 feet or more in all directions.

(c) Locate heaters used near combustible tarpaulins, canvas, or similar coverings at least 10 feet from the coverings and securely fasten them to prevent ignition or upsetting of the heater due to wind action on the covering or other material.

(d) Liquid-fired heaters must have a primary safety control to stop the flow of fuel in the event of flame failure.

NOTE: Barometric or gravity oil feed is not a primary safety control.

(e) Do not use heating devices without built-in means to effectively control the fuel supply and the flame in occupied buildings.

(D) Since liquefied petroleum gas is in a closed system of piping and equipment, the system does not need to be electrically conductive or electrically bonded for protection against static electricity.

(E) Open flames, cutting or welding, portable electric tools, and extension lights capable of igniting LP-Gas, must not be in classified areas in Table 6 unless the LP-Gas facilities are free of all liquid and vapor. [Table and Figure not included. See ED. NOTE.]

(q) Fixed electrical equipment in classified areas. Fixed electrical equipment and wiring in classified areas in Table 6 must comply with Table 6 and subdivision 4/S. This provision does not apply to fixed electrical equipment at residential or commercial installations of LP-Gas systems or to systems covered by OAR 437-004-0780(4).

(r) Liquid-level gaging device.

(A) Each container made after December 31, 1965, and filled on a volumetric basis must have a fixed liquid-level gage to indicate the maximum filling level as in OAR 437-004-0780(b)(19)(v). Each container made after December 31, 1969, must have permanently attached to the container adjacent to the fixed level gage a marking showing the percentage full that will be shown by that gage. When there is also a variable liquid-level gage, the fixed gage will also serve as a way to check the variable gage. OAR 437-004-0780(b)(12) requires these gages in charging containers.

(B) Arrange all variable gaging devices so that the maximum allowed liquid level for butane, for a 50-50 mixture of butane and propane, and for propane, is readily determinable. The markings indicating the various liquid levels from empty to full must be on the system nameplate or gaging device or part may be on the system nameplate and part on the gaging device. Dials of magnetic or rotary gages must show whether they are for cylindrical or spherical containers and whether for aboveground or underground service. The dials of gages intended for use only on aboveground containers of over 1,200 gallons water capacity must be so marked.

(C) Gaging devices that require bleeding of the product to the atmosphere, such as the rotary tube, fixed tube, and slip tube, must have a bleed valve maximum opening not larger than .0550 inch, unless they have an excess flow valve.

(D) Gaging devices must have a design working pressure of at least 250 p.s.i.g.

(E) Length of tube or position of fixed liquid-level gage must indicate the maximum fill level of the container for the product contained. This level must be based on the volume of the product at 40°F at its maximum permitted filling density for aboveground containers and at 50°F for underground containers. The employer must calculate the filling point for which the fixed liquid level gage must be designed according to the method in this subdivision.

(i) It is impossible to set out in a table the length of a fixed dip tube for various capacity tanks because of the varying tank diameters and lengths and because the tank may be installed either in a vertical or horizontal position. Knowing the maximum permitted filling volume in gallons, however, the length of the fixed tube can be determined by the use of a strapping table obtained from the container manufacturer. The length of the fixed tube should be such that when its lower end touches the surface of the liquid in the container, the contents of the container will be the maximum permitted volume as determined by the following formula: [Formula not included. See ED. NOTE.]

(ii) Formula for determining maximum volume of liquefied petroleum gas for which a fixed length of dip tube must be set: [Table not included. See ED. NOTE.]

(iii) The maximum volume of LP-Gas that can be in a container when determining the length of the dip tube expressed as a percentage of total water content of the container is calculated by the following formula.

(iv) The maximum weight of LP-Gas which may be placed in a container for determining the length of a fixed dip tube is determined by multiplying the maximum volume of liquefied petroleum gas obtained by the formula in (3)(r)(E)(i) above by the pounds of liquefied petroleum gas in a gallon at 40°F for aboveground and at 50°F for underground containers. For example, typical pounds per gallon are below: [Formula not included. See ED. NOTE.]

(F) Fixed liquid-level gages on containers other than DOT containers must be stamped on the exterior of the gage with the letters “DT” followed by the vertical distance (expressed in inches and carried out to one decimal place) from the top of container to the end of the dip tube or to the centerline of the gage when it is at the maximum permitted filling level. For portable containers that may be filled in the horizontal and/or vertical position the letters “DT” must be followed by “V” with the vertical distance from the top of the container to the end of the dip tube for vertical filling and with “H” followed by the proper distance for horizontal filling. For DOT containers the stamping must be both on the exterior of the gage and on the container. On above-ground or cargo containers where the gages are positioned at specific levels, the marking may be in percent of total tank contents and the marking must be on the container.

(G) Columnar gage glasses must be restricted to charging plants where the fuel is withdrawn in the liquid only. They must have valves with metallic handwheels, excess flow valves, and extra-heavy glass adequately protected with a metal housing applied by the gage manufacturer. They must be shielded against the direct rays of the sun. Do not use columnar gage glasses on tank trucks, motor fuel tanks or on containers used in domestic, commercial, and industrial installations.

(H) Gaging devices of the float, or equivalent type that do not require flow for their operation and with connections extending to a point outside the container do not have to have excess flow valves if the piping and fittings will withstand the container pressure and are properly protected against physical damage.

(s) Requirements for appliances.

(A) Except as in (3)(s)(B) below, new commercial and industrial gas consuming appliances must be approved.

(B) If an appliance was made to use a gas other than LP-Gas, it may be used with LP-Gas only after it is properly converted, adapted and tested for performance before placing it in use.

(C) Unattended heaters inside buildings for animal or poultry production or care must have an approved automatic device to shut off the gas if the flame goes out.

Fuel containers on passenger-carrying vehicles must be as far from the engine as practicable. There must be a seal between the passenger space or any space with radio equipment and the container space to prevent direct seepage of gas to these spaces. The container compartment must vent to the outside. If the fuel container is near the engine or the exhaust system, shield it from direct heat.

(B) Mount all fuel containers to prevent jarring loose, slipping, or rotating. The fastenings must withstand static loading in any direction equal to twice the weight of the tank and attachments when filled using a safety factor of not less than four.

(iii) For containers used only on farm tractors and charged at a point at least 50 feet from any building, the fixed liquid-level gaging device may equal that passed by a .1200 inch opening. You do not need an excess flow valve. Mark fittings with the restricted opening and the container they are on to show the size of the opening.

(iv) Protect all valves and connections on containers from damage. For farm tractors where parts of the vehicle protect the valves and fittings, this requirement is met. On removable containers the protection for the fittings must be permanently attached.

(v) For systems with removable fuel containers, there must be a way in the system to minimize the escape of fuel when exchanging containers. Either of these methods are acceptable:

(I) Using an approved automatic quick-closing coupling (a type closing in both directions when uncoupled) in the fuel line, or

(II) Closing the valve at the fuel container and allowing the engine to run until the fuel line is empty.

Use a rain cap or other protector to keep water and dirt from collecting in the valve.

(C) When using a discharge line from the container safety relief valve, the line must be metallic, other than aluminum, and may not restrict the required flow of gas from the safety relief valve. Such discharge line must be able to withstand the pressure resulting from the discharge of vapor when the safety relief valve is fully open. When flexibility is necessary, use flexible metal hose or tubing.

Hazardous Waste Operations and Emergency Response (HAZWOPER)

(1) If an agricultural employer requires employees to respond to an emergency release of a hazardous chemical with a reasonable possibility for employee exposure to safety or health hazards, that response activity must be in compliance with the applicable sections of Division 2/H, 1910.120, Hazardous Waste Operations and Emergency Response.

(2) Agricultural employers whose activities include clean-up operations involving hazardous waste, including those conducted at a treatment, storage, and disposal (TSD) facility, are subject to the applicable requirements in Division 2/H, 1910.120, Hazardous Waste Operations and Emergency Response.

NOTES: There are two primary considerations for most agricultural employers to determine if the HAZWOPER rules apply to you:

(1) Do you expect your employees to respond to spills of hazardous chemicals in a way that involves a reasonable possibility of exposure to safety or health hazards? (If NO, the HAZWOPER rules do not apply.)

(2) If YES, would your employees respond only to an incidental release of a hazardous chemical; or, to an emergency release of a hazardous chemical?

(a) IF you expect your employees to respond only to an incidental release (defined as a situation where the spilled substance can be absorbed, neutralized, or otherwise controlled at the time of release by employees in the immediate area, or by maintenance personnel;) and there is no potential safety or health hazard (such as fire, explosion, or chemical exposure;) THEN, the HAZWOPER RULES DO NOT APPLY. However, you must train and equip employees who are expected to respond to incidental releases to safely handle that type of non-routine task as required by Division 4/Z, 437-004-9800, Hazard Communication Standard for Agricultural Employers.)

(b) IF you expect your employees to respond to an emergency release (defined as an occurrence that results in, or is likely to result in an uncontrolled release of a hazardous substance; or, a situation that requires a response effort by employees from outside the immediate release area, or by other designated responders such as mutual-aid groups or local fire departments;) THEN, the HAZWOPER RULES APPLY. Agricultural employers who expect their employees to respond to these types of emergencies are required to follow the sections in the HAZWOPER rules that apply to emergency releases “without regard to the location of the hazard.” (See Division 2/H, 1910.120(q) Emergency responses to hazardous substance releases.) The best source of information about any chemical in the workplace (including recommended personal protective equipment and procedures for spill-response) is often the chemical’s Safety Data Sheet (SDS.)

437-004-1041

Respiratory Protection

(1) Permissible practice.

(a) To control occupational diseases caused by breathing contaminated air, the best method is to prevent contamination with engineering controls. To the extent feasible, accepted engineering controls must be used. Examples of engineering controls include enclosing the source of contamination, providing general or local exhaust ventilation to remove the contaminated air from work areas, and substituting less toxic materials. When this approach is not feasible, or while engineering controls are being established, employers must provide appropriate respirators in compliance with this standard.

(b) You must provide a respirator to each employee when it is necessary to protect their health. Respirators must be appropriate for the hazard. You must also establish and maintain an effective respiratory protection program that includes at least the requirements outlined in paragraph (3) of this standard. The program must cover each employee required to use a respirator.

(2) Definitions. The following definitions apply to this standard. Air-purifying respirator is a respirator with an air-purifying filter, cartridge, or canister that removes specific air contaminants by passing ambient air through the air-purifying element. Assigned protection factor (APF) means the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program as specified by this section. Atmosphere-supplying respirator is a respirator that supplies the user with breathing air from a source independent of the ambient atmosphere, and includes supplied-air respirators (SARs) and self-contained breathing apparatus (SCBA) units. Canister or cartridge is a container with a filter, sorbent, or catalyst, or combination of these items, that removes specific contaminants from the air passed through the container. Competent person is a person who, because of training and experience, can identify existing and predictable hazards in equipment, material, conditions or practices and who has the knowledge and authority to take corrective steps. Demand respirator is an atmosphere-supplying respirator that admits breathing air to the face piece only when inhalation creates a negative pressure inside the face piece. Elastomer (elastomeric) is an elastic substance like rubber or neoprene. Emergency situation is any event such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment that may or does result in an uncontrolled significant release of an airborne contaminant. Employee exposure is exposure to a concentration of an airborne contaminant that would occur if the employee were not using respiratory protection. End-of-service-life indicator (ESLI) is a device, on the cartridge, that warns respirator users when their respirator is near the end of its ability to protect them. For example, an indicator on the cartridge will change to warn the user that the cartridge sorbent material is nearing saturation and is no longer effective. Engineering control measures are methods to eliminate or control employee exposure to the hazard; e.g., substitution of a less toxic material, general or local ventilation and enclosing the operation. Escape-only respirator is a respirator only for use during emergency exit. Filter or air purifying element is a respirator component (e.g., canister or cartridge) that removes solid or liquid aerosols from the inspired air. Filtering face piece (dust mask) is a tight fitting negative pressure particulate respirator with a filter as an integral part of the face piece or with the entire face piece made of the filtering medium. Fit factor is a quantitative estimate of the fit of a particular respirator to a specific person, and typically estimates the ratio of the concentration of a substance in ambient air to its concentration inside the respirator when worn. Instrumentation is used with ambient air as the “test agent” to quantify the respirator fit. See Appendix A. Fit test is the use of procedures in Appendix A to qualitatively or quantitatively evaluate the fit of a respirator on a person. (See also Qualitative fit test QLFT and Quantitative fit test QNFT.) Helmet is a rigid respirator covering that also provides head protection against impact and penetration. High efficiency particulate air (HEPA) filter is a filter that is at least 99.97 percent efficient in removing monodisperse particles of 0.3 micrometers in diameter. The equivalent NIOSH 42 CFR 84 particulate filters are the N100, R100, and P100 filters. Hood is a respirator covering that completely covers the head and neck and may also cover portions of the shoulders and torso. Immediately dangerous to life or health (IDLH) is an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual’s ability to escape from a dangerous atmosphere. Interior structural firefighting is the physical activity of fire suppression, rescue or both, inside of buildings or enclosed structures which are involved in a fire situation beyond the incipient stage. Loose-fitting face piece is a respiratory covering that forms a partial seal with the face, e.g., hood. Maximum use concentration (MUC) means the maximum atmospheric concentration of a hazardous substance from which an employee can be expected to be protected when wearing a respirator, and is determined by the assigned protection factor of the respirator or class of respirators and the exposure limit of the hazardous substance. The MUC can be determined mathematically by multiplying the assigned protection factor specified for a respirator by the required OSHA permissible exposure limit, short-term exposure limit, or ceiling limit. When no OSHA exposure limit is available for a hazardous substance, an employer must determine an MUC on the basis of relevant available information and informed professional judgment. Negative pressure respirator (tight fitting) is a respirator in which the air pressure inside the face piece is negative during inhalation with respect to the ambient air pressure outside the respirator. Oxygen deficient atmosphere is an atmosphere with an oxygen content less than 19.5 percent by volume. Physician or other licensed health care professional (PLHCP) is a person whose legally permitted scope of practice (i.e., license, registration, or certification) allows them to independently provide, or be delegated to provide, some or all of the health care services required by this standard. Positive pressure respirator is a respirator in which the pressure inside the respiratory covering is higher than the air pressure outside the respirator. Powered air-purifying respirator (PAPR) is an air-purifying respirator that uses a blower to force the ambient air through air-purifying elements to the inlet covering. Pressure demand respirator is a positive pressure atmosphere-supplying respirator that admits breathing air to the face piece when inhalation reduces the positive pressure inside the face piece. Qualitative fit test (QLFT) is a pass/fail fit test to assess the adequacy of respirator fit that relies on the individual’s response to the test agent. See Appendix A. Quantitative fit test (QNFT) is an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator. See Appendix A. Respirator covering is that part of a respirator that forms the protective barrier between the user’s respiratory tract and an air-purifying device or breathing air source, or both. It may be a face piece, helmet, hood, suit, or a mouthpiece respirator with nose clamp. Self-contained breathing apparatus (SCBA) is an atmosphere-supplying respirator for which user carries the breathing air source. Service life is the period of time that a respirator, filter or sorbent, or other respiratory equipment adequately protects the wearer. Supplied-air respirator (SAR) or airline respirator is an atmosphere-supplying respirator for which the source of breathing air is not carried by the user. Tight-fitting face piece is a respirator covering that forms a complete seal with the face, e.g., half mask or full-face piece. User seal check is an action by the respirator user to determine if the respirator is properly seated to the face. See appendix B-1.

(3) Respiratory protection program.

(a) When respirators are necessary to protect the health of workers or when you require workers to wear them, you must have an effective, written respiratory protection program, managed by a knowledgeable person, with procedures specific to your work site. Keep the program updated to reflect changes in conditions that require the use of respirators. You must include at least these points, as applicable:

(A) Procedures for selecting respirators for use in the workplace;

(B) Procedures for the medical evaluations of employees required to use respirators;

(C) Fit testing procedures for tight-fitting respirators;

(D) Procedures for proper use of respirators in routine and reasonably foreseeable emergency situations;

(E) Procedures and schedules for cleaning, disinfecting, storing, inspecting, repairing, discarding, and otherwise maintaining respirators;

(F) Procedures to ensure adequate air quality, quantity, and flow of breathing air for atmosphere-supplying respirators;

(G) Procedures for training employees in the respiratory hazards to which they are potentially exposed during routine and emergency situations;

(H) Procedures for training employees in the proper use of respirators, including putting on and removing them, any limitations on their use, and their maintenance; and

(I) Procedures for regularly evaluating the effectiveness of the program.

(b) The employer must provide respirators, and all other program requirements including training, and medical evaluations at no cost to the employee.

(c) Where respirator use is voluntary:

(A) You may provide respirators to employees who request them or they may use their own respirators. If you allow this voluntary use;

(i) You must determine that it will not create a hazard to the user;

(ii) You must provide the voluntary user with the information in Appendix D, “Information for Employees Using Respirators When Not Required Under the Standard”; and

(B) You must have a limited written respiratory program for voluntary users. It must include those parts of the standard program necessary to ensure that:

(i) The user is medically able to use the respirator without adverse health effects. Users of tight-fitting respirators other than dust masks must have a medical evaluation.

(ii) The user will properly clean, store and maintain the respirator.

(4) Selection of respirators. Identify and evaluate the respiratory hazard(s) including a reasonable estimate of employee exposures and an identification of the contaminant’s chemical state and physical form. You must treat atmospheres with the potential for IDLH conditions as an IDLH hazard and provide appropriate respiratory protection.

(a) General requirements.

(A) You must evaluate respiratory hazards, conditions in the workplace and user factors, then select and provide the appropriate respirators.

(B) All respirators must have NIOSH certification and all use must conform to that certification.

(C) Respirators must correctly fit and be acceptable to the user.

(b) Respirators for IDLH atmospheres.

(A) Provide the following respirators for employee use in IDLH atmospheres:

(i) A full-face piece pressure demand SCBA certified by NIOSH for a minimum service life of 30 minutes, or

(ii) A combination full-face piece pressure demand supplied-air respirator (SAR) with auxiliary self-contained air supply.

(B) Respirators only for escape from IDLH atmospheres must have NIOSH certification for escape from the atmosphere of use.

(C) Treat all oxygen-deficient atmospheres as IDLH.

EXCEPTION to paragraph (4)(b)(C): If you can demonstrate that under all foreseeable conditions, the oxygen concentration will stay within the ranges in Table A for the appropriate altitudes set out in the table, then your selection of atmosphere-supplying respirators is not limited to the types listed in (4)(b)(A). Table A

(c) Respirators for atmospheres that are not IDLH.

(A) Provide respirators adequate to protect the health of workers and ensure compliance with all other OR-OSHA requirements, under routine and reasonably foreseeable emergency situations.

(i) Assigned Protection Factors (APFs). Employers must use the assigned protection factors listed in Table B to select a respirator that meets or exceeds the required level of employee protection. When using a combination respirator (e.g., airline respirators with an air-purifying filter), employers must ensure that the assigned protection factor is appropriate to the mode of operation in which the respirator is being used. Table B.

(ii) Maximum Use Concentration (MUC).

(I) The employer must select a respirator for employee use that maintains the employee’s exposure to the hazardous substance, when measured outside the respirator, at or below the MUC.

(II) Employers must not apply MUCs to conditions that are immediately dangerous to life or health (IDLH); instead, they must use respirators listed for IDLH conditions in paragraph (4)(b) of this standard.

(III) When the calculated MUC exceeds the IDLH level for a hazardous substance, or the performance limits of the cartridge or canister, then employers must set the maximum MUC at that lower limit.

(B) The respirator must be appropriate for the chemical state and physical form of the contaminant.

(C) For protection against gases and vapors, provide:

(i) An atmosphere-supplying respirator, or

(ii) An air-purifying respirator, if:

(I) It has and end-of-service-life indicator (ESLI) certified by NIOSH for the contaminant; or

(II) If there is no ESLI appropriate for your conditions, implement a change schedule for canisters and cartridges that is based on objective information or data that will ensure that canisters and cartridges are changed before the end of their service life. Describe in the respirator program the information and data relied on and the basis for the canister and cartridge change schedule and the basis for reliance on the data.

NOTE: The Worker Protection Standard contains criteria for specific change out schedules for respirator canisters and cartridges. See Division 4/W, 170.240.

(D) For protection against particulates, provide:

(i) An atmosphere-supplying respirator; or

(ii) An air-purifying respirator with a filter certified by NIOSH under 30 CFR part 11 as a high efficiency particulate air (HEPA) filter, or an air-purifying respirator with a filter certified for particulates by NIOSH under 42 CFR part 84; or

(iii) For contaminants consisting primarily of particles with mass median aerodynamic diameters (MMAD) of at least 2 micrometers, an air-purifying respirator with any filter certified for particulates by NIOSH.

(5) Medical evaluation. Using a respirator may place a physiological burden on employees that depends on the type of respirator, the job and workplace conditions in which the respirator is used, and the medical status of the employee.

(a) General. You must provide medical evaluations to determine each worker’s ability to use a respirator without causing adverse health effects. Do this before the worker’s fit test and before they perform any work requiring respirator use. The employer may discontinue an employee’s medical evaluations when the employee no longer uses a respirator.

(b) Medical evaluation procedures. The employer must identify a physician or other licensed health care professional (PLHCP) to perform medical evaluations using a medical questionnaire or an initial examination that obtains the same information as the medical questionnaire. The medical evaluation must obtain the information requested by the questionnaire in Appendix C, Part A, Sections 1 and 2, of this standard.

NOTE: If the employee refuses the examination, they may not be permitted to work in jobs that require a tight-fitting respirator.

(c) Follow-up medical examination.

(A) The employer must ensure that a follow-up medical examination is provided for an employee if, in the opinion of the PLHCP, this is necessary.

NOTE: The PLHCP may require a follow-up examination for an employee who gives a positive response to any question among questions 1 through 9, or 10 through 15 in Appendix C, Part A, Section 2; or whose initial medical examination demonstrates the need for a follow-up medical examination.

(B) The follow-up medical examination must include any medical tests, consultations, or diagnotic procedures that the PLHCP deems necessary to make a final determination.

(d) Administration of the medical questionnaire and examinations.

(A) You must allow the employee to complete the questionnaire in a way that protects the confidentiality of the information. Employers are not allowed to see the answers or to review the completed form. You must allow employees to complete the form during normal working hours or at a time and place convenient to them. If employees need help, allow them to ask your PLHCP or anybody other than their employer or representtatives of their employer.

(B) The employer must provide the employee with an opportunity to discuss the questionnaire and examination results with the PLHCP.

(e) Supplemental information for the PLHCP.

(A) You must give the PLHCP the required supplemental information before they make any recommendation about a worker’s ability to use a respirator. Use Appendix C, Part B, Section 2 of this standard, or an equivalent form to provide this information.

(i) The type and weight of the respirator the employee will use;

(ii) How long and how often the employee will use the respirator (including use for rescue and escape);

(iii) The expected physical work effort while using the respirator;

(iv) Additional protective clothing and equipment to be worn; and

(v) Temperature and humidity extremes that may exist during use.

(B) Supplemental information you provide for an employee’s medical evaluation does not have to be provided again for later evaluations unless the information or the PLHCP changes.

(C) You must provide a copy of your written respiratory program and this standard to the PLHCP.

Note to Paragraph (5)(e): When the employer replaces a PLHCP, the employer must ensure that the new PLHCP has this information, either by providing the documents directly to the new PLHCP or by having the documents transferred from the former PLHCP to the new PLHCP. However, OR-OSHA does not expect employers to have employees medically reevaluated solely because there is a new PLHCP.

(f) Medical determination. In determining the employee’s ability to use a respirator, the employer must:

(A) Obtain a written recommendation about the employee’s ability to use the respirator from the PLHCP. The recommendation must provide only the following information:

(i) Any limitations on respirator use relating to the medical condition of the employee, or relating to the workplace conditions, including whether or not the employee is medically able to use the respirator;

(ii) The need, if any, for follow-up medical evaluations; and

(iii) A statement that the PLHCP gave a copy of the recommendation to the worker.

(B) If the respirator is a negative pressure respirator and the PLHCP finds that using it would increase the employee’s health risk, the employer must provide a PAPR until a subsequent evaluation clears the employee for another type.

(g) Additional medical evaluations. At a minimum, the employer must provide additional medical evaluations that comply with this standard if:

(A) An employee reports medical signs or symptoms related to ability to use a respirator;

(B) A PLHCP, supervisor, or the knowledgeable person who manages the respiratory protection program informs the employer that an employee needs a reevaluation; or

(C) Information from the respiratory protection program, including observations made during fit testing and program evaluation, indicates a need for employee reevaluation; or

(D) A change occurs in work conditions (such as physical work effort, protective clothing, and temperatures) that may result in a substantial increase in the physiological burden to the employee.

(6) Fit testing. You must:

(a) Ensure that employees using a tight-fitting face piece respirator pass an appropriate qualitative fit test (QLFT) or quantitative fit test (QNFT), using the same make, model, style and size respirator that they will use in the workplace.

(b) Ensure that each worker using a tight-fitting face piece respirator is fit-tested, before initial respirator use; whenever they change to another type, style, model, or make of respirator, and at least annually thereafter.

(c) Do a new fit test on a worker when you observe or the worker, a supervisor, the program administrator, or a PLCHP report any change in the worker’s physical condition that could affect the respirator fit. Such conditions include, but are not limited to, facial scarring, dental changes, cosmetic surgery, or an obvious change in body weight.

(d) Give employees a reasonable opportunity to select a different respirator face piece and redo the fit test if, after passing a QLFT or QNFT, the employee notifies the employer, supervisor, or PLHCP that the fit of the respirator is unacceptable.

(e) Ensure that all fit tests comply with the accepted QLFT or QNFT protocols in Appendix A of this standard.

(f) Ensure that qualitative fit tests (QLFT) are used only to fit test negative pressure air-purifying respirators that must achieve an assigned protective factor of 50 or less.

(g) Ensure that quantitative fit tests (QNFT), using an accepted QNFT protocol, are only passed by achieving a fit factor of 100 or more for a tight fitting half face piece respirator, and a fit factor of 500 or more for a tight fitting full face piece respirator.

(h) Ensure that fit testing of tight-fitting atmosphere-supplying respirators and tight-fitting powered air-purifying respirators is only accomplished by performing quantitative or qualitative fit testing in the negative pressure mode, regardless of the mode of operation (negative or positive pressure) that is used for respiratory protection.

(A) Do qualitative fit testing of these respirators by temporarily converting the respirator user’s actual face piece into a negative pressure respirator with appropriate filters, or by using an identical negative pressure air-purifying respirator face piece with the same sealing surfaces as a surrogate for the atmosphere-supplying or powered air-purifying respirator face piece.

(B) Do quantitative fit testing of these respirators by modifying the face piece to allow sampling inside the face piece in the breathing zone of the user, midway between the nose and mouth. Do this by installing a permanent sampling probe onto a surrogate face piece, or by using a sampling adapter designed to temporarily provide a way to sample air from inside the face piece.

(C) Before returning a face piece to normal use, completely remove any modifications done for fit testing, and restore the face piece to NIOSH-approved configuration.

(7) Use of respirators.

(a) Face piece seal protection.

(A) You must not permit workers to wear tight-fitting face pieces if they have:

(i) Facial hair that comes between the face-to-face piece sealing surface or that interferes with the respirator’s valve function; or

(ii) Any other condition that interferes with the face-to-face piece seal or valve function.

(B) If an employee wears glasses or goggles or other personal protective equipment, the employer must ensure that it does not interfere with the seal of the face piece to the face of the user.

(C) Employers must ensure that workers who wear respirators perform a user seal check before every use, using the procedures in Appendix B-1 or, if equally effective, the recommendations of the respirator manufacturer.

(b) Continuing respirator effectiveness.

(A) You must reevaluate the effectiveness of a respirator when there is a change in work area conditions or degree of employee exposure or stress that may affect respirator effectiveness.

(B) You must ensure that employees leave the area where respirators are required:

(i) To wash their faces and respirator face pieces as necessary to prevent eye or skin irritation associated with respirator use; or

(ii) If they detect vapor or gas breakthrough, changes in breathing resistance, or leakage of the face piece; or

(iii) To replace the respirator or the filter, cartridge, or canister elements.

(C) If the employee detects vapor or gas breakthrough, changes in breathing resistance, or leakage of the face piece, the employer or a competent person must replace or repair the respirator before allowing the employee to return to the work area.

(c) Procedures for IDLH atmospheres. For all IDLH atmospheres, the employer must ensure that:

(A) One employee or, when needed, more than one employee is stationed outside the IDLH atmosphere;

(B) Visual, voice, or line communication is continuous between the employee(s) in the IDLH atmosphere and the employee(s) outside the IDLH atmosphere;

(C) The employee(s) outside the IDLH atmosphere have the training and equipment to provide effective emergency rescue;

(D) The employer or designee is notified before the employee(s) outside the IDLH atmosphere enter the IDLH atmosphere to provide emergency rescue;

(E) The employer or designee authorized to do so by the employer, once notified, provides necessary assistance appropriate to the situation;

(F) Employee(s) outside the IDLH atmospheres have:

(i) Pressure demand or other positive pressure SCBAs, or a pressure demand or other positive pressure supplied-air respirator with auxiliary SCBA; and either:

(ii) Appropriate retrieval equipment for removing the employee(s) who enter(s) these hazardous atmospheres where retrieval equipment would contribute to the rescue of the employee(s) and would not increase the overall risk resulting from entry; or

(iii) Equivalent means for rescue when there is no requirement for retrieval equipment under paragraph (7)(c)(F)(ii).

(d) Procedures for interior structural firefighting. If you require your workers to fight interior structural fires, paragraph (7)(c) applies. You must also do the following:

(A) At least two employees enter the IDLH atmosphere and remain in visual or voice contact with one another at all times; and

(B) At least two employees are located outside the IDLH atmosphere; and

(C) All employees engaged in interior structural firefighting use SCBA’s.

NOTE 1 to paragraph (7)(d):One of the two individuals located outside the IDLH atmosphere may be assigned to an additional role, such as incident commander in charge of the emergency or safety officer, so long as this individual is able to perform assistance or rescue activities without jeopardizing the safety of health of any firefighter working at the incident.

NOTE 2 to paragraph (7)(d): Nothing in this section is meant to preclude firefighters from performing emergency rescue activities before an entire team has assembled.

(8) Maintenance and care of respirators.

(a) Cleaning and disinfecting. You must provide each respirator user with a respirator that is clean, sanitary, and in good working order. You also must ensure that respirators are cleaned and disinfected using the procedures in Appendix B-2, or equally effective procedures recommended by the respirator manufacturer, at the following intervals:

(A) Clean and disinfect respirators used exclusively by one worker as often as necessary to keep them sanitary;

(B) Clean and disinfect respirators after each use, or before being worn by different individuals, if used by more than one worker;

(C) Clean and disinfect emergency use respirators after each use; and

(D) Clean and disinfect fit test and training respirators after each use.

Be certain the regulator and warning devices work properly.

(D) For emergency use respirators, the employer must:

(i) Certify the respirator by documenting the date of inspection, the name (or signature) of the inspector, the findings, required remedial action, and a serial number or other means of identifying the respirator; and

(ii) Provide this information on a tag or label attached to the respirator storage compartment, or keep it with the respirator, or include it in paper or electronic inspection reports. Keep this information until the next report replaces it.

(d) Repairs. Do not use respirators that fail an inspection or are otherwise defective. Either discard them or repair them according to these procedures:

(A) Only people with appropriate training may repair or adjust respirators. They must use only the manufacturer’s NIOSH-approved parts designed for the particular respirator;

(B) Repairs must conform to the manufacturer’s recommendations for the type of repair to be performed;

Confined and Hazardous Spaces

(1) Definitions.

(a) Competent person is somebody who can identify existing and predictable hazards and take measures to eliminate them.

(b) Confined space is a space that:

(A) Is large enough and so configured that an employee can bodily enter and work; and

(B) Has limited or restricted entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits may have limited entry); and

(C) Is not designed for continuous employee occupancy.

(c) Engulfment is the covering of a person by a liquid or finely divided (flowable) solid substance that when inhaled causes death or that can exert enough force on the body to cause death by strangulation, constriction or crushing.

(d) Entry is passing through an opening into a hazardous or confined space. Entry includes work in the space and occurs when any part of the entrant’s body breaks the plane of an opening into the space in a way that creates a hazard.

(e) IDLH Atmospheres. Atmospheres immediately dangerous to life or health (IDLH) are those with less than 19.5 percent oxygen by volume, or which because of the high toxicity of the contaminant, would endanger the life of a person breathing them for even a short period of time.

(f) Oxygen-deficient is an atmosphere with less than 19.5 percent oxygen by volume.

(2) Fuel bins.

(a) Fuel bins must have adequate exits and all necessary devices to provide safety for employees who enter them.

(b) There may be sentry stations or tunnels near the bottom conveyor for employees to use to stoke down congested fuel through openings. Safely built pneumatic bottoms, mechanical agitators or scrapers and similar devices are acceptable.

(3) Entering confined spaces.

(a) Test first. Always test the atmosphere in a confined space before an employee places any part of their body into it. Following the instructions below, test first for oxygen, then flammable atmosphere then toxic atmosphere.

(b) Entry. No person will enter or work in any confined space with an atmosphere immediately dangerous to life or health, except under the following conditions:

(A) They must wear a supplied air or self-contained air breathing apparatus;

(B) They must wear a safety belt with lifeline attached, where practical. Another person, equipped as required in subsection (3)(b)(A) above and with safety belt and lifeline attached, must be at the opening with adequate help available to remove the person if necessary (see (5), Rescue below);

(C) Failure of the person within the enclosure to respond to agreed upon signals requires immediate rescue action by a person or persons equipped as required in subsections (3)(b)(A) and (B) above;

(D) Air supplied to hose masks and positive pressure air helmets must be free from harmful dusts, fumes, mists, vapors, or gases to the extent that breathing it does not constitute harmful exposure. Position the air intake to the blower fan or compressor to prevent contamination of the air by carbon monoxide or other hazardous materials or gases;

(E) Supplied air respiratory equipment must have an automatic pressure relief valve, and connect through a pressure reduction valve in the supply line. Maximum allowable pressure, unless otherwise specifically approved, is 25 pounds per square inch;

(F) To assure safety when using positive-pressure air respiratory equipment, a minimum volume of air delivered to the user must be at least 4 cubic feet of air per minute for a face mask and 6 cubic feet of air per minute for hoods or helmets.

(c) Oxygen-deficient atmospheres. The atmosphere in a sealed or unventilated confined space is considered immediately dangerous to life or health. Nobody will enter such space unless:

(A) All requirements for safety equipment and procedures in (3)(b) above are met; or

(B) A competent person tests the atmosphere with an oxygen indicator or other suitable device immediately before entry to ensure that it contains enough oxygen to sustain life; or

(C) Until mechanical ventilation provides at least one complete change of uncontaminated air immediately before entry and continues while anybody is inside the enclosure. A safety watcher meeting the requirements in (3)(b) above must be at the entry.

(d) Toxic atmospheres. Nobody will enter any sealed or unventilated tank or other confined space that contains or has contained toxic materials or gases, unless:

(A) All requirements for safety equipment and safety procedures in (3)(b) above are met, or a competent person tests the atmosphere with an appropriate instrument or method and finds it to have contaminants below the threshold limit values of the particular material or gas.

(B) If the atmosphere has concentrations of hazardous contaminants not immediately dangerous to life or health, but above the threshold limit values for the toxic material, the person entering the space must wear respiratory protective equipment approved by the National Institute of Occupational Safety and Health, or recommended by the U.S. Department of Agriculture for the exposure.

(e) Flammable or explosive atmospheres. The atmosphere in any sealed or unventilated tank or other confined space and that contains or has contained combustible or flammable materials or gases is an atmosphere immediately dangerous to life or health.

(A) Nobody must enter such space unless all requirements for safety equipment and safety procedures in (3)(b) above are met or atmosphere tests by a competent person using an appropriate instrument or method shows no flammable or explosive atmosphere is present.

(B) If the atmosphere contains flammable or explosive vapors at or above 20 percent of their lower explosive limit, ventilate the space enough to bring the level below 20 percent of the lower explosive limit. Otherwise only persons meeting the requirements of (c) above may enter the enclosure for emergency work, including preparatory work or work to set up equipment to eliminate the gas.

(f) Ventilation. Natural and/or mechanical ventilation must maintain the atmosphere within the limits permissible for explosive or toxic materials and gases while employees are in the space.

(g) Residues and other sources. When there could be a release of explosive or toxic materials from residues or other sources in a confined space, there must be additional testing as necessary to assure the atmosphere has not become immediately dangerous to life or health. If such conditions arise, immediately leave the contaminated space until the atmosphere is safe for persons wearing respiratory protective equipment.

(h) Physical hazards. Do not allow employees to enter confined spaces that contains physical hazards, until you comply with OAR 437-004-1275.

(i) Engulfment. Do not allow employees to enter confined spaces where there is a hazard from engulfment by collapsing material.

(j) Lifeline and attendant. When entering confined spaces that have loose material (such as chips, sand, grain, gravel, sawdust, etc.) you must wear a safety belt with lifeline. There must be an attendant for the lifeline.

(k) Lockout/tagout. Follow the procedures of OAR 437-004-1275, for intake pipelines that convey hazardous substances into confined spaces before workers enter. Blinds, if used, must clearly show whether the line is open or closed. Close, lock and attach warning tags to valves in such lines nearest the containers. Blinding or lockout of cold water and air lines is not necessary if they have positive control valves near the container and you lock, close and tag the valves.

(4) Training.

(a) Train all workers before they do anything covered by this section. Retrain workers when there are changes in their duties or the spaces related to this section.

(b) Training must cover all hazards associated with the employer’s confined and hazardous spaces.

(c) Training must cover this standard and all duties associated with it.

(d) Keep written documentation of all training until it is superseded by new training.

(5) Rescue.

(a) These requirements apply to employers who have employees enter confined spaces to rescue people.

(A) You must give each rescuer the personal protective equipment and rescue equipment necessary to make rescues from hazardous spaces. You must also provide training on the proper use of that equipment.

(B) Train each rescuer in basic first aid and in cardiopulmonary resuscitation (CPR). At least one rescuer with current certification in first aid and in CPR must be available.

(b) When employers arrange to have persons other than their own employees do confined space rescue, the employer must:

(A) Inform the rescue service of the hazards they may confront during the rescue at the host employer’s facility; and

(B) Provide the rescue service with access to all confined spaces from which rescue may be necessary so that the rescue service can develop appropriate rescue plans and practice rescue operations.

(c) To accomplish non-entry rescue, attach the other end of the retrieval line to a mechanical device or fixed point outside the hazardous space in a way that rescue can begin as soon as the rescuer becomes aware that rescue is necessary.
