1. Which federal regulation primarily governs asbestos abatement
activities in the workplace?
A. OSHA Bloodborne Pathogens Standard
B. OSHA Asbestos Standard (29 CFR 1926.1101)
C. EPA Clean Water Act
D. HUD Lead Rule
The OSHA Asbestos Standard establishes requirements for exposure
limits, work practices, respiratory protection, and training in
asbestos-related construction activities.
2. The current OSHA permissible exposure limit (PEL) for asbestos is:
A. 0.1 fibers/cc
B. 0.5 fibers/cc
C. 0.1 fibers per cubic centimeter as an 8-hour TWA
D. Zero tolerance
The OSHA PEL limits occupational asbestos exposure to 0.1 fibers per
cubic centimeter averaged over an 8-hour work shift.
3. Before starting an asbestos abatement project, the supervisor must
ensure:
A. Workers sign payroll forms
B. A written site-specific compliance plan is in place
C. The building is demolished
D. Only gloves are provided
, A written compliance plan ensures proper controls, procedures, and
safety measures are established before work begins.
4. Which respiratory protection is typically required for Class I asbestos
work?
A. Surgical mask
B. Half-mask without cartridges
C. Appropriate NIOSH-approved respirator
D. Dust mask
NIOSH-approved respirators are required because asbestos fibers are
hazardous and require certified respiratory protection.
5. A negative pressure enclosure is designed to:
A. Increase airflow into the work area
B. Prevent asbestos fibers from escaping the containment area
C. Dry materials quickly
D. Remove debris automatically
Negative pressure systems prevent contaminated air from leaving
the containment area.
6. The purpose of HEPA filtration is to remove:
A. Odors
B. Moisture
C. Very small airborne particles including asbestos fibers
D. Carbon monoxide
HEPA filters are capable of capturing at least 99.97% of particles 0.3
microns in size.
7. Which agency enforces asbestos regulations in Nevada workplaces?
A. CDC
B. FEMA
C. OSHA
D. DOT
OSHA enforces occupational asbestos standards in construction and
general industry settings.
8. A supervisor must ensure workers receive training:
A. Once every 10 years
B. Only if requested
C. Before engaging in asbestos work and annually thereafter
, D. After project completion
Initial and annual asbestos training ensures workers understand
hazards and safe work practices.
9. Which material is most likely to contain friable asbestos?
A. Vinyl floor tile
B. Roofing shingles
C. Sprayed-on insulation
D. Cement board
Sprayed-on insulation is easily crumbled and releases fibers into the
air.
10. Decontamination units must include:
A. Break room access
B. Storage closet
C. Clean room, shower, and dirty room
D. Office space
Proper decontamination units prevent contamination from spreading
outside the work area.
11. Air monitoring during abatement is conducted to:
A. Track worker attendance
B. Measure airborne fiber concentrations
C. Reduce humidity
D. Replace respirators
Air monitoring verifies compliance with exposure limits and work
controls.
12. Waste asbestos materials must be disposed of in:
A. Regular trash bins
B. Recycling centers
C. Approved asbestos waste disposal facilities
D. Open fields
Asbestos waste must be handled and disposed of according to
regulatory requirements.
13. The supervisor’s role includes:
A. Performing only clerical tasks
B. Ensuring compliance with safety regulations
C. Ignoring air monitoring results
