TSCA and governs asbestos management in K–12 schools.
2. What is the permissible exposure limit (PEL) for asbestos according to
Cal/OSHA?
A. 0.2 f/cc over 30 minutes
B. 0.1 f/cc as an 8-hour TWA
C. 1.0 f/cc as a ceiling limit
D. 0.01 f/cc as a short-term limit
Rationale: The Cal/OSHA PEL for asbestos is 0.1 fibers per cubic centimeter
(f/cc) over an 8-hour time-weighted average.
,3. The AHERA requirement for re-inspection of asbestos-containing
materials (ACMs) in schools is every:
A. 2 years
B. 3 years
C. 5 years
D. 6 months
Rationale: AHERA requires re-inspection of known or assumed ACMs in
schools every 3 years.

A. A solid ACM in good condition
B. An ACM that can be crumbled or reduced to powder by hand pressure
C. A wet ACM
D. Any asbestos product used in cement
