Why respiratory protection is necessary
Air contaminants/hazardous atmospheres come from a variety of sources•Dusts•Aerosol mists•Metal fumes

Cleaning, maintenance, and storage
Respirators must be cleaned to remove contaminants/prevent irritation
Shared respirators must be cleaned before each use
(School administrators and/or managers assign individual-use respirators to employees who are authorized for respirator use)
![Page 19: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134.](https://reader036.fdocuments.in/reader036/viewer/2022081504/56649ea95503460f94bad5d5/html5/thumbnails/19.jpg)

Responding to Emergencies
If the respirator malfunctions, immediately leave the work area
Activate auxiliary self-contained air supply (ESD 101 School Program does not use auxiliary air
supply since no self-contained respirators are utilized in the program)
![Page 22: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134.](https://reader036.fdocuments.in/reader036/viewer/2022081504/56649ea95503460f94bad5d5/html5/thumbnails/22.jpg)
