1. The primary purpose of an asbestos building inspection is to:
A. Determine building age
B. Identify and assess asbestos-containing materials
C. Measure indoor air quality
D. Approve demolition permits
Answer: B
Rationale: The main objective of an asbestos inspection is to locate,
identify, and evaluate the condition of asbestos-containing materials
(ACMs) to manage exposure risk.
, 2. Asbestos-containing material (ACM) is defined as any material
containing asbestos in excess of:
A. 0.1%
B. 0.5%
C. 1.0%
D. 5.0%
Answer: C
Rationale: Regulations define ACM as material containing more than 1%
asbestos by weight.
3. Which type of asbestos was most commonly used in building
materials?
A. Crocidolite
B. Amosite
C. Tremolite
D. Chrysotile
Answer: D
Rationale: Chrysotile (white asbestos) accounts for the majority of

A. Hard hat only
B. Safety goggles only
C. Respirator and protective clothing
D. Hearing protection
Answer: C
Rationale: Sampling can disturb ACM, requiring respiratory and dermal
