model number of respirator chosen
AHERA regulations cover:
1
all projects
projects in public buildings
projects in school buildings
glove bag projects
Surfactants are added to water which is used to spray asbestos so that the:
1
material is easier to remove
work area is cooler
material breaks up better
water is absorbed easier
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:
1

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

inhalation valve
face-piece
straps and buckles
hoses
Asbestos-related diseases usually occur:
1
upon immediate exposure
a few years after exposure

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

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