A. OSHA 1910.1200
B. EPA 40 CFR Part 61, Subpart M
C. DOT 49 CFR Part 172
D. ANSI Z9.2
This regulation, known as the NESHAP standard, governs emission

demolition.
,2. What type of asbestos is most commonly found in buildings?
A. Crocidolite
B. Chrysotile
C. Amosite
D. Tremolite
Chrysotile (white asbestos) accounts for about 90–95% of asbestos used in
buildings due to its flexibility and heat resistance.
3. Which type of respirator is typically required for workers in Class I
asbestos work?
A. Dust mask
B. Half-face air-purifying respirator
C. Powered air-purifying respirator (PAPR)
D. Full-face negative pressure respirator
A full-face respirator provides eye and respiratory protection from
asbestos fibers and is a minimum requirement for Class I work.
4. How often must negative exposure assessments be conducted if
exposures remain consistent?
A. Initially and every 6 months
B. Once per year
C. Every time a job starts
D. Only if requested by OSHA
If the exposure conditions remain constant and below the PEL, assessments
should be conducted initially and then biannually.
,5. What is the permissible exposure limit (PEL) for asbestos as per OSHA?
A. 1.0 f/cc
B. 0.2 f/cc
C. 0.1 f/cc
D. 0.01 f/cc
OSHA's PEL for asbestos is 0.1 fiber per cubic centimeter of air, averaged
over an 8-hour work shift.
6. What is the required action level (AL) for asbestos?
A. 0.2 f/cc
B. 0.15 f/cc
C. 0.1 f/cc
D. 0.05 f/cc
The AL is the same as the PEL—0.1 f/cc—which triggers certain
requirements like air monitoring and medical surveillance.
7. What type of glove is recommended for asbestos abatement work?
A. Latex gloves

accordance with:
A. EPA Worker Protection Rule
B. EPA Model Accreditation Plan
C. NFPA 70E
D. DOT Hazmat
The Model Accreditation Plan requires specific training for supervisors,
including how to oversee asbestos abatement projects.
10. What is the purpose of a glovebag?
A. To store gloves
B. To decontaminate tools
C. To dispose of asbestos
D. To enclose small-scale asbestos removal
Glovebags are used for small-scale removal (like pipe insulation) to contain
fibers and prevent contamination.
11. What must be included in the project design for asbestos abatement?
A. Estimated project profit
