Respiratory Protection29 CFR 1910.134

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

Types of Face Pieces

Mouthpiece Single use/disposable Quartermask Half mask Full face Helmet

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

Revision to 1910.134

Effective date: April 8, 1998 Enforcement date: October 5, 1998

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
