Regulatory Requirements

WAC 296-62-070 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

Page 5: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

5

Types of Face Pieces

Mouthpiece Single use/disposable Quartermask Half mask Full face Helmet

Page 6: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

6

Effective Use of Respirators

During installation of engineering controls During maintenance operations During process turnarounds For non-routine tasks For emergency response At hazardous waste site operations When other controls are inadequate When other controls are not feasible

Page 7: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

7

Employee Effectiveness

The use of respiratory protection limits the effectiveness of the employee by 33.33 percent.

Page 8: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

8

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

Page 12: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

12

Respiratory Program (cont.)

Inspection and evaluation to determine effectiveness

Medical examinations Approved respirators

Page 13: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

13

Written Program Requirements

Must be site-specific Must have a program administrator Must be developed when respirator

use is required

Page 14: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

14

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 non-required users

Page 15: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

15

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

Page 16: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

16

General Requirements

Use of NIOSH-approved respirators only Evaluation of hazards Availability of multiple respirator types

Page 17: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

17

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

Page 18: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

18

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

Page 19: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

19

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

Page 20: 1/05 School Safety Training Respiratory Protection WAC 296-841 / 296-842

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
