TRANSCRIPT
Regulatory Requirements
29 CFR 1910.134 Covers all required and voluntary use of
respiratory protection in general industry Requires a written program Requires employee training, medical
evaluation, and fit-testing Standard revised in 1998
Types of Respiratory Protection
Atmosphere supplying– Self-contained
breathing apparatus (SCBA)
– Airline respirators
Air purifying– Gas and vapor– Particulate– Combination
Effective Use of Respirators
During installation ofengineering controls During maintenance operations During process turnarounds For nonroutine tasks For emergency response At hazardous waste site operations When other controls are inadequate When other controls are not feasible
Employee Effectiveness
The use of respiratory protection limits the effectiveness of the employee by 33.33 percent.
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?
Types of Fit-testing
Qualitative– Isoamyl acetate– Irritant smoke
Quantitative– DOP/corn oil– Ambient atmosphere
(portacount)
Elements of a Respiratory Protection Program
Written operating procedures Proper selection Training and fitting Cleaning and disinfecting Storage Inspection and maintenance Work area surveillance
Respiratory Program (cont.)
Inspection and evaluation to determine effectiveness
Medical examinations Approved respirators
Written Program Requirements
Must be site-specific Must have a program administrator Must be developed when respirator
use is required
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
Respirators Not Required (cont.)
If dust masks only are used and not required, no written program is required
Appendix D of the standard must be provided to users
General Requirements
Use of NIOSH-approved respirators only Evaluation of hazards Availability of multiple respirator types
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
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
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
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 changes

Quiz Answers
1. The two categories of respiratory protection are atmosphere-supplying and air-purifying.
2. False. An employee’s effectiveness will decrease about one-third while using a respirator.
3. True. Employees who are required to wear respirators must be physically qualified to wear the devices.
4. The two types of fit-testing are qualitative and quantitative.
5. False. Respirators accepted by OSHA must be NIOSH approved.
Quiz Answers (cont.)
6. Types of respirator face pieces include mouthpiece, single-use disposable, quarter mask, half mask, full face, and helmet.
7. True. The protection factor of a half mask respirator is 10 x PEL.
8. Elements of a written respiratory protection program include written operating procedures, proper selection, training and fitting, cleaning and disinfecting, storage, inspection and maintenance, and work area surveillance.
9. False. Respirator fit-testing must be conducted annually.10. False. Only an air-supplying respirator will protect you from
chemical fumes.
