MIOSHA Respiratory Protection Program
A. Respirator Program
1. If respirators, including self-contained breathing apparatus, are used, the department must have a written Respiratory Protection Program, which
details the procedure for respirator selection, medical assessment of respirator user health, training, proper fitting, respirator inspection and
maintenance, and recordkeeping. A model written program is available through EHS.
2. Every respirator user must attend training and be fit-tested by EHS annually. These sessions are scheduled as needed through the Industrial
Hygiene staff of EHS. Please contact EHS if training or fit-testing is needed.
3. For each respirator user, the department must have available a record of the respirator user’s name, type of respirator and cartridges used, and the
dates of attendance for respirator training and fit-testing.
4. Respirator users must have medical approval by a physician at McCosh Health Center. Medical approval requires initial and periodic physicals
and an annual review of a completed medical surveillance questionnaire completed at the time of fit-testing.
B. Air Purifying Respirator Inspection
1. The respirator facepiece must be in good condition in order to provide a good fit. Respirators may become less flexible over time and use,
which may prohibit a good seal to the face, resulting in leakage.
2. For full-facepiece respirators, the lens should be cleared. Replacement lenses and removable lens shields are available through most
manufacturers and distributors.
3. Head straps may lose elasticity over time. Replacement straps are available from most distributors.
4. Replacement headstraps, buckles and attachments are available through most distributors.
5. Self-explanatory.
6. Self-explanatory. Replacement valves are available through most distributors.
7. Self-explanatory.
8. There are many types of cartridges available for protection from different hazards. If the cartridge or filter is inappropriate for the hazard, the
respirator will not provide protection from that hazard. See manufacturer information for availability of cartridges. An Industrial Hygienist
from EHS must review all respirator use to recommend the appropriate cartridge or filter.
35
MIOSHA-ADM-05-2R1

MIOSHA Respiratory Protection Program
9. Self-explanatory.
10. Air purifying respirators must have a rubber gasket at the base of the inhalation valve to facilitate sealing of the canister or filter to the
respirator.
11. Cartridges or filters must be replaced either when breathing becomes more difficult due to loading of the filter or if odors from the hazardous
substance are detectable.

Appendix F
Definitions
1. AIR-PURIFYING RESPIRATOR (APR) means a respirator with an air-purifying
filter, cartridge, or canister that removes specific air contaminants by passing ambient air
through the air-purifying element.
2. 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.
3. ATMOSPHERE-SUPPLYING RESPIRATOR (ASR) means a respirator that
supplies the respirator 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.
4. CANISTER OR CARTRIDGE means a container with a filter, sorbent, or catalyst, or
combination of these items, which removes specific contaminants from the air passed
through the container.
5. EMERGENCY SITUATION means any occurrence 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.
6. EMPLOYEE EXPOSURE means exposure to a concentration of an airborne
contaminant that would occur if the employee were not using respiratory protection.
7. END-OF-SERVICE-LIFE INDICATOR (ESLI) means a system that warns the
respirator user of the approach of the end of adequate respiratory protection, for
example, that the sorbent is approaching saturation or is no longer effective.
8. ESCAPE-ONLY RESPIRATOR means a respirator intended to be used only for
emergency exit.
9. FILTER OR AIR PURIFYING ELEMENT means a component used in respirators to
remove solid or liquid aerosols from the inspired air.
10. FILTERING FACEPIECE (dust mask) means 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.
11. FIT FACTOR means a quantitative estimate of the fit of a particular respirator to a
specific individual, and typically estimates the ratio of the concentration of a substance
in ambient air to its concentration inside the respirator when worn.
37
MIOSHA-ADM-05-2R1
March 27, 2007
MIOSHA Respiratory Protection Program
12. FIT TEST means the use of a protocol to qualitatively or quantitatively evaluate the fit
of a respirator on an individual. (See also qualitative fit test and quantitative fit test.)
13. HELMET means a rigid respiratory inlet covering that also provides head protection
against impact and penetration.
14. HIGH EFFICIENCY PARTICULATE AIR (HEPA) FILTER means a filter that is
at least 99.97% 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.
15. HOOD means a respiratory inlet covering that completely covers the head and neck and
may also cover portions of the shoulders and torso.
16. IMMEDIATELY DANGEROUS TO LIFE OR HEALTH (IDLH) means 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.
17. INTERIOR STRUCTURAL FIREFIGHTING means the physical activity of fire
suppression, rescue or both, inside of buildings or enclosed structures that are involved
in a fire situation beyond the incipient stage. (See MIOSHA Part 74. Fire Fighting)
18. 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 MIOSHA permissible exposure limit,
short-term exposure limit, or ceiling limit. When no MIOSHA 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.
19. NEGATIVE PRESSURE RESPIRATOR (TIGHT-FITTING) means a respirator in
which the air pressure inside the facepiece is negative during inhalation with respect to
the ambient air pressure outside the respirator.
20. NIOSH means National Institute for Occupational Safety and Health.
21. OXYGEN DEFICIENT ATMOSPHERE means an atmosphere with an oxygen
content below 19.5% by volume.
22. PHYSICIAN OR OTHER LICENSED HEALTH CARE PROFESSIONAL
(PLHCP) means an individual whose legally permitted scope of practice (i.e., license,
registration, or certification) allows him or her to independently provide, or be delegated

MIOSHA Respiratory Protection Program
the responsibility to provide, some or all of the health care services required by
1910.134(e) of MIOSHA Part 451, “Respiratory Protection.”.
23. POWERED AIR-PURIFYING RESPIRATOR (PAPR) means an air-purifying
respirator that uses a blower to force the ambient air through air-purifying elements to
the inlet covering.
24. QUALITATIVE FIT TEST (QLFT) means a pass/fail fit test to assess the adequacy of
respirator fit that relies on the individual's response to the test agent.
25. QUANTITATIVE FIT TEST (QNFT) means an assessment of the adequacy of
respirator fit by numerically measuring the amount of leakage into the respirator.
26. RESPIRATORY INLET COVERING means that portion 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 facepiece, helmet, hood, suit, or a mouthpiece
respirator with nose clamp.
27. SELF-CONTAINED BREATHING APPARATUS (SCBA) means an atmospheresupplying respirator for which the breathing air source is designed to be carried by the
user.
28. SERVICE LIFE means the period of time that a respirator, filter or sorbent, or other
respiratory equipment provides adequate protection to the wearer.
29. SUPPLIED-AIR RESPIRATOR (SAR) OR AIRLINE RESPIRATOR means an
atmosphere-supplying respirator for which the source of breathing air is not designed to
be carried by the user..
30. TIGHT-FITTING FACEPIECE means a respiratory inlet covering that forms a
complete seal with the face.
31. USER SEAL CHECK means an action conducted by the respirator user to determine if
the respirator is properly seated to the face.
