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

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

1
tell if ACM is present
remove some of the asbestos fibers out of the air
prevent heat exposure
determine asbestos fiber level in the air

1
Type C supplied-air
Powered air purifying
Half-face air purifying
Full-face air purifying
Smoking:
1
has no effect on asbestos -related diseases
decreases the risk of asbestos related disease
increases the risk of asbestos related disease
prevents asbestos related disease
According to OSHA, negative air pressure is required:
