1. Hazardous Materials Identification
Q: Hazardous materials include all of the following EXCEPT: A) Asbestos B)
Brake Cleaner C) Engine Oil D) Water
Correct Answer: D
Explanation: Water is chemically inert and non-hazardous. Asbestos, brake
cleaner, and engine oil all contain chemical compounds that are regulated
because they pose significant health or environmental risks.
Q: To determine if a product or substance being used is hazardous, consult:
A) SAE standards B) Dictionary C) EPA guidelines D) An MSDS (or SDS)
Correct Answer: C * Note: While an MSDS/SDS is the document you use
on the job to check specific handling procedures, the EPA (Environmental
Protection Agency) is the authoritative body that defines and classifies
substances as "hazardous."
2. Asbestos Safety
Q: Exposure to asbestos dust can cause what condition? A) Lung cancer B)
Asbestosis C) Mesothelioma D) All of the above
Correct Answer: D
Explanation: Asbestos fibers are microscopic and needle-like. Once
inhaled, they cause permanent damage to lung tissue, leading to chronic
scarring (asbestosis), tumors (mesothelioma), and cell mutation (lung
cancer).
Q: Wetted asbestos is considered to be: A) Hazardous waste B) Solid waste C)
Toxic D) Poisonous
Correct Answer: B
, Explanation: This is a specific regulatory distinction. Asbestos is
"hazardous" when it is friable (able to be turned into airborne dust). By
wetting it, you prevent the fibers from becoming airborne, which reclassifies
the material as "solid waste" for the purpose of safe transport and disposal.
