3. 3 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

4. 4 Types of Respiratory Protection  Atmosphere supplying Self-contained breathing apparatus (SCBA) Airline respirators  Air purifying Gas and vapor Particulate Combination

5. 5 Types of Face Pieces  Mouthpiece  Single use/disposable  Quartermask  Half mask  Full face  Helmet

6. 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

7. 7 Employee Effectiveness The use of respiratory protection limits the effectiveness of the employee by 33.33 percent.

8. 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.

9. 9 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?

10. 10 Types of Fit-testing  Qualitative Isoamyl acetate Irritant smoke  Quantitative DOP/corn oil Ambient atmosphere (portacount)

11. 11 Elements of a Respiratory Protection Program  Written operating procedures  Proper selection  Training and fitting  Cleaning and disinfecting  Storage  Inspection and maintenance  Work area surveillance

12. 12 Respiratory Program (cont.)  Inspection and evaluation to determine effectiveness  Medical examinations  Approved respirators

13. 13 Written Program Requirements  Must be site-specific  Must have a program administrator  Must be developed when respirator use is required

14. 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

15. 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

16. 16 General Requirements  Use of NIOSH-approved respirators only  Evaluation of hazards  Availability of multiple respirator types

17. 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

18. 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

19. 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

20. 20 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

21. 21 Quiz 1. The two categories of respiratory protection are ________________ and ___________________. 2. An employee’s effectiveness increases while using a respirator. True or False 3. Employees who are required to wear respirators must first be medically qualified. True or False 4. The two types of respirator fit-testing are ________________ and ___________________. 5. All respirators used for employee protection must be WISHA approved. True or False

22. 22 Quiz (cont.) 6. Types of respirator facepieces include _____________, ___________, and ____________. 7. The protection factor of a half mask air-purifying respirator is 10 x PEL. True or False 8. Elements of a written respiratory protection program include __________, ________, and ___________. 9. Respirator fit-testing must be conducted every three years. True or False 10. Any respirator you use will protect you against harmful chemical fumes. True or False

23. 23 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 WISHA must be NIOSH approved.

24. 24 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.
