AHERA regulations cover:
1
glove bag projects
all projects
projects in public buildings
projects in school buildings
Surfactants are added to water which is used to spray asbestos so that the:

work area is cooler
material is easier to remove
material breaks up better
The _____ offers the MOST protection.
1
disposable respirator
half-facepiece air purifying respirator with cartridges
SCBA
powered air purifying respirator
Eating, drinking, smoking, chewing (gum or tobacco) or applying cosmetics is only permitted:

replace the filters
do positive and negative pressure fit tests
When inspecting a half-facepiece negative pressure air-purifying respirator, you do NOT need to check for defects in the:
1

prevent heat exposure
tell if ACM is present

drinking plenty of water
If fiber levels on an asbestos job are greater than 1.0 f/cc, which CANNOT be worn?
1
Full-face air purifying
Type C supplied-air
Powered air purifying
Half-face air purifying
Smoking:
1
decreases the risk of asbestos related disease
has no effect on asbestos -related diseases
increases the risk of asbestos related disease
