1. In Maryland asbestos supervisor responsibilities, which primary duty is
required when overseeing Class I asbestos work in a regulated facility?
A. Conducting only final clearance air sampling without daily oversight
B. Ensuring compliance with federal OSHA and state-approved
asbestos control procedures during abatement activities
C. Delegating all containment inspection duties to unlicensed laborers
D. Allowing unrestricted dry removal when fibers are visibly dampened
B. Ensuring compliance with federal OSHA and state-approved
asbestos control procedures during abatement activities
A supervisor is legally responsible for ensuring that asbestos
abatement work follows OSHA standards and Maryland regulations,
including proper containment, worker protection, and procedural
compliance throughout the job.
,2. Which material is most commonly associated with friable asbestos in
older building insulation systems?
A. Fiberglass batts installed after 2005
B. Cement board used in modern construction
C. Spray-applied fireproofing and thermal insulation materials
D. Polyurethane foam sealants used in HVAC systems
C. Spray-applied fireproofing and thermal insulation materials
Spray-applied fireproofing and insulation materials are often friable
and can easily release airborne asbestos fibers when disturbed.
3. What is the most important initial step before disturbing suspect
asbestos-containing material (ACM)?
A. Wetting the material without inspection
B. Conducting a certified asbestos inspection and material assessment
C. Removing material immediately to reduce exposure time
D. Ventilating the area to disperse fibers
B. Conducting a certified asbestos inspection and material
assessment
Proper identification of ACM through certified inspection is required
before any disturbance to ensure safe and legal handling procedures.
4. Which respiratory protection is typically required for Class I asbestos
work?
A. Simple dust mask
B. Surgical mask
C. Half-face air-purifying respirator without HEPA filters
D. Full-face respirator with HEPA filtration or supplied-air system
depending on exposure level
D. Full-face respirator with HEPA filtration or supplied-air system
depending on exposure level
OSHA requires appropriate respirators with HEPA filtration or
, supplied-air systems based on exposure risk to prevent inhalation of
asbestos fibers.
5. What is the purpose of a negative air pressure system in asbestos
containment areas?
A. To increase airflow into the work zone
B. To prevent water accumulation in containment
C. To ensure air flows into the containment, preventing fiber escape
D. To dry asbestos materials quickly
C. To ensure air flows into the containment, preventing fiber escape
Negative air pressure systems maintain inward airflow to prevent
asbestos fibers from escaping into surrounding environments.
6. Which agency sets federal standards for asbestos exposure in the
workplace?
A. EPA only
B. OSHA
C. FEMA
D. CDC exclusively
B. OSHA
The Occupational Safety and Health Administration establishes
permissible exposure limits and safety requirements for asbestos in
workplaces.
7. Which type of asbestos material is considered the most hazardous due
to its friability?
A. Non-friable vinyl floor tile
B. Cement pipe
C. Spray-applied insulation
D. Asbestos-containing asphalt roofing
C. Spray-applied insulation
, Spray-applied asbestos materials are highly friable and easily release
airborne fibers when disturbed.
8. What is the function of a HEPA filter in asbestos abatement
equipment?
A. To increase airflow efficiency only
B. To trap at least 99.97% of airborne particles including asbestos
fibers
C. To humidify the air inside containment
D. To neutralize asbestos chemically
B. To trap at least 99.97% of airborne particles including asbestos
fibers
HEPA filters are designed to capture extremely small particles,
including hazardous asbestos fibers, from the air.
9. Which practice is strictly prohibited during asbestos removal?
A. Wet methods for fiber control
B. Use of HEPA vacuums
C. Dry sweeping or dry removal of friable ACM
D. Proper containment setup
C. Dry sweeping or dry removal of friable ACM
Dry methods disturb asbestos fibers and significantly increase
airborne contamination risk.
10. What is the purpose of personal air monitoring in asbestos
abatement work?
A. To measure noise levels in containment
B. To determine asbestos fiber concentration in a worker’s breathing
zone
C. To monitor humidity levels in work areas
D. To track equipment efficiency only
B. To determine asbestos fiber concentration in a worker’s breathing
