4. The _____ offers the MOST protection.
1
half-facepiece air purifying respirator with cartridges
SCBA
powered air purifying respirator
disposable respirator
5. Eating, drinking, smoking, chewing (gum or tobacco) or applying cosmetics is only permitted:

SCBA (Air Tank)
Disposable dust mask
Powered air purifying respirator (PAPR)
7. After putting on a respirator and BEFORE entering the work area, a worker should:
1
clean the respirator
replace the filters
do positive and negative pressure fit tests
inspect the respirator
8. When inspecting a half-facepiece negative pressure air-purifying respirator, you do NOT need to check for defects in the:

makes the asbestos less toxic
helps keep the worker cooler
