seal between face-piece and the face
model number of respirator chosen
AHERA regulations cover:
1
projects in public buildings
all projects
glove bag projects
projects in school buildings
Surfactants are added to water which is used to spray asbestos so that the:
1
water is absorbed easier
material breaks up better
material is easier to remove
work area is cooler
The _____ offers the MOST protection.
1
powered air purifying respirator
SCBA
half-facepiece air purifying respirator with cartridges
disposable respirator
Eating, drinking, smoking, chewing (gum or tobacco) or applying cosmetics is only permitted:
1
in the shower
outside of the work area
in the work area
in the equipment room
Your employer gives you a half-face respirator. OSHA says you may require your employer to give you a better respirator. What respirator can you ask for?
1
Disposable dust mask
SCBA (Air Tank)
Full face negative pressure
Powered air purifying respirator (PAPR)
After putting on a respirator and BEFORE entering the work area, a worker should:
1
replace the filters
inspect the respirator
do positive and negative pressure fit tests
clean the respirator
When inspecting a half-facepiece negative pressure air-purifying respirator, you do NOT need to check for defects in the:
1
straps and buckles
inhalation valve
face-piece
hoses
Asbestos-related diseases usually occur:
1
a few years after exposure
several months after exposure

1
reduces the amount of airborne asbestos
makes the material easier to remove
helps keep the worker cooler
makes the asbestos less toxic
Air sampling is conducted to
1
determine asbestos fiber level in the air
tell if ACM is present
remove some of the asbestos fibers out of the air
prevent heat exposure

taking salt tablets
If fiber levels on an asbestos job are greater than 1.0 f/cc, which CANNOT be worn?
1
Half-face air purifying
Type C supplied-air
Powered air purifying
Full-face air purifying
Smoking:
1
decreases the risk of asbestos related disease
has no effect on asbestos -related diseases
prevents asbestos related disease
increases the risk of asbestos related disease
According to OSHA, negative air pressure is required:
1
never
only when fiber levels exceed 0.1 f/cc
constantly during an asbestos project
only when workers are present
