breathing apparatus (SCBA)
– Airline respirators
Air purifying– Gas and vapor– Particulate– Combination

Maximum Use Concentrations
Half mask w/ov cartridge = 1,000 ppm or 10x the PEL, whichever is lower
Full face w/ov cartridge = 1,000 ppm or 50x the PEL, whichever is lower
Full face w/acid gas chin canister = 2% by volume or 50 times the PEL, whichever is lower
Note: In general, never exceed an APF.

Respirator Selection Criteria
Physical state of the contaminant
Contaminant concentration Oxygen deficiency Warning properties
of contaminant Potential for IDLH atmospheres Can contaminant be
ad/absorbed by a media? Can contaminant be ad/absorbed by the skin? Is the contaminant irritating to the eyes?

use is required
11006115 Copyright 1999 Business and Legal Reports, Inc.
When Respirators Are Not Required
Can use employee respirator if it does not create a hazard
Voluntary users of respirators must be given Appendix D
Appendix D = employee information when respirators are not required
Employers must implement a program for nonrequired users
11006115 Copyright 1999 Business and Legal Reports, Inc.
Respirators Not Required (cont.)

General Requirements
Use of NIOSH-approved respirators only Evaluation of hazards Availability of multiple respirator types
11006115 Copyright 1999 Business and Legal Reports, Inc.
Respirators for Non-IDLH Use
If cartridges have no “end of service life indicator” a change schedule must be used
Added table for oxygen-deficient atmospheres based on altitude
11006115 Copyright 1999 Business and Legal Reports, Inc.
Medical Evaluation
Use of medical questionnaire (Appendix C) Follow-up medical exam for any positive
response to questionnaire All medical evaluations must be made
confidentially Employees must be allowed to discuss
the questionnaire with the physician
11006115 Copyright 1999 Business and Legal Reports, Inc.
Medical Evaluation (cont.)
Physicians must be told conditions of respirator use
Employers must provide a PAPR if employees cannot use a negative pressure APR
Follow-up evaluations must be conducted if conditions of use or user health change
11006115 Copyright 1999 Business and Legal Reports, Inc.
Fit-Testing
Respirators will not protect you if they don’t fit properly!
Required for negative or positive pressure tight-fitting face pieces
Must be conducted prior to use Must be conducted at least annually Must be retested if respirator fit or
wearer change
