1. Which agency sets the federal standards for asbestos exposure in the
workplace?
A. FDA
B. OSHA
C. EPA
D. CDC
Rationale: OSHA sets federal occupational exposure limits and standards
for asbestos in the workplace.
2. What is the maximum allowable concentration of asbestos fibers in air
over an 8-hour time-weighted average (TWA)?
, A. 0.5 fibers/cm³
B. 1.0 fibers/cm³
C. 0.1 fibers/cm³
D. 5 fibers/cm³
Rationale: OSHA's permissible exposure limit (PEL) for asbestos is 0.1 fibers
per cubic centimeter (f/cc) as an 8-hour TWA.
3. Which type of asbestos is most commonly used in building materials?
A. Crocidolite
B. Chrysotile
C. Amosite
D. Tremolite
Rationale: Chrysotile, or white asbestos, is the most widely used type in

adequate protection against airborne asbestos fibers.
9. What is the first step before starting an asbestos abatement project?
A. Begin removal immediately
B. Conduct a thorough asbestos survey and risk assessment
C. Remove all furniture from the building
D. Install negative air machines
Rationale: An asbestos survey identifies all asbestos-containing materials
