This document provides an overview of OSHA's Respiratory Protection Standard 29 CFR 1910.134. It discusses requirements for employer-provided respiratory protection training, elements of a written respiratory protection program, types of respirators including air-purifying and atmosphere-supplying respirators, and fit testing requirements. Key aspects of the standard include selecting appropriate respirators based on hazards, developing a written program with medical evaluation and maintenance procedures, and training employees annually and when conditions change. The goal is ensuring employees required to use respirators are properly protected from airborne contaminants.

10. Filter
A component used in
respirators to remove solid or
liquid aerosols from the
inspired air. Also called air
purifying element.

11. Canister or Cartridge
A container with a filter, sorbent, or catalyst, or
combination of these items, which removes specific
contaminants from the air passed through the
container.

12. Filtering Facepiece
(Dust Mask)
A negative pressure particulate respirator with a
filter as an integral part of the facepiece or with
the entire facepiece composed of the filtering
medium.

13. Air-Purifying Respirator (APR)
A respirator with an air-purifying
filter, cartridge, or canister that
removes specific air contaminants
by passing ambient air through the
air-purifying element.

14. Powered Air-Purifying Respirator
(PAPR)
An air-purifying respirator that uses
a blower to force the ambient air
through air-purifying elements to the
inlet covering.

15. Supplied Air Respirator (SAR)
An atmosphere-supplying respirator for which
the source of breathing air is not designed to be
carried by the user. Also called airline
respirator.

16. Grade “D” Air
• Oxygen Content of 19.5-23.5%
• Hydrocarbon (condensed) content of 5
milligrams per cubic meter of air or less
• Carbon monoxide (CO) content of 10 ppm
or less
• Carbon dioxide content of 1,000 ppm or
less; and
• Lack of noticeable odor

17. Respirator Program
• Must develop a written program with
worksite-specific procedures when
respirators are necessary or required by
the employer
• Must update program as necessary to
reflect changes in workplace conditions
that affect respirator use
• Must designate a program
administrator to evaluate the program.

18. Respirator Program (cont’d)
Where Respirator Use is Not Required
• If voluntary use is permissible, employer
must provide users with the information
contained in Appendix D
• Must establish and implement those
elements of a written program necessary
to ensure that employee is medically
able to use the respirator and that it is
cleaned, stored, and maintained so it
does not present a health hazard to
the user

1. Selection
2. Medical evaluation
3. Fit testing
4. Use
5. Maintenance and care
6. Breathing air quality and use
7. Training
8. Program evaluation

20. Immediately Dangerous
to Life or Health (IDLH)
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.

22. End-of-Service-Life Indicator
(ESLI)
A system that warns the user of the approach of the
end of adequate respiratory protection; e.g., the
sorbent is approaching saturation or is no longer
effective.

23. Fit Testing
Before an employee uses any respirator with a
negative or positive pressure tight-fitting
facepiece, the employee must be fit tested with
the same make, model, style, and size of
respirator that will be used.

24. Training and Information
Employers must provide effective training
to employees who are required to use
respirators.

25. Training and Information
• Employees who are required to use
respirators must be trained such that
they can demonstrate knowledge of at
least:
– why the respirator is necessary and how
improper fit, use, or maintenance can
compromise its protective effect
– limitations and capabilities of the respirator
– effective use in emergency situations
– how to inspect, put on and remove, use
and check the seals

26. Training and Information (cont’d)
• Training must be provided prior to use,
unless acceptable training has been
provided by another employer within the
past 12 months
• Retraining is required annually, and
when:
– changes in the workplace or type of
respirator render previous training obsolete
– there are inadequacies in the employee’s
knowledge or use
– any other situation arises in which
