1. What is the physical composition of minerals classified as asbestos?
Asbestos is a collective term for a variety of naturally occurring silicate minerals
that share a distinct structural characteristic. ✔✔ Answer: They form long, thin,
and durable fibers.
2. What components typically comprise a standard protective clothing
ensemble for hazardous material remediation? Proper Personal Protective
Equipment (PPE) is essential to prevent "take-home" contamination and skin
contact with hazardous dust. ✔✔ Answer: A specialized hood, booties, and
disposable coveralls.
3. Which of the following tasks is categorized as an OSHA Class II asbestos
operation? OSHA classifies asbestos work based on the type of material and the
likelihood of fiber release during the activity. ✔✔ Answer: The removal of 5 feet
of pipe insulation specifically to facilitate a mechanical repair, such as fixing a
leak.
4. How is "make-up air" typically introduced into a negative pressure
enclosure? To maintain a safe environment, air must flow from clean areas into
the contaminated work zone through controlled openings. ✔✔ Answer: Through
holes strategically cut in the polyethylene sheeting adjacent to the air filtration
machines.
, 5. What are the mandatory requirements for disposing of asbestos-containing
waste? Because asbestos fibers are hazardous when airborne, disposal must follow
strict containment protocols to prevent accidental release. ✔✔ Answer: All waste
must be placed in sealed, leak-tight, and properly labeled containers or
specialized wraps.
6. What is the primary pathway for asbestos to enter the human body? While
ingestion is possible, the most significant health risks are associated with
microscopic particles being drawn into the respiratory system. ✔✔ Answer:
Inhalation.
7. What safety features are mandatory for a free-standing mobile scaffold that
is 16 feet high? In addition to having lockable wheels, a minimum width of 4 feet,
and regular inspection by a competent person, specific fall protection is required.
✔✔ Answer: A complete system of guard rails.
The removal of all specified asbestos-containing materials -ANSWER ✔✔A final
visual inspection is used to determine which one of the final steps of an abatement
project?
50-90 times -ANSWER ✔✔How much greater is the incidence of lung cancer in
asbestos workers who smoke than in non-asbestos workers who do not smoke?
Personal air monitoring -ANSWER ✔✔Which of the following records must be
kept for a minimum of 30 years?
Any job where the amount of friable ACM being removed is less than 260 linear
feet or 160 square feet -ANSWER ✔✔AHERA regulations allow PCM to be used
as a method of analysis for:
