Painting a contaminated surface Class I work includes activities involving the removal of TSI and surfacing ACM.
- When must negative pressure enclosures be used? A. In small-scale projects only B. When asbestos levels are below the PEL C. During large-scale removal of friable ACM D. Only during final clearance
A. Begin removal immediately B. Notify neighbors C. Notify EPA/state agency and post warnings D. Apply disinfectant Notification of authorities and warning signs must be posted before starting asbestos work.
- What is the primary health hazard associated with asbestos exposure? A. Asthma B. Mesothelioma C. Skin cancer D. Liver failure Asbestos exposure is strongly linked to mesothelioma, a fatal lung-related cancer.
- Which personal protective equipment (PPE) is required for workers during asbestos abatement? A. Leather gloves B. Dust masks C. Full-face respirator and disposable suits D. Safety goggles only
A full-face respirator with HEPA filters and disposable suits are required to protect against asbestos exposure.
- What type of filter is used in respirators for asbestos? A. P B. N C. HEPA D. Charcoal HEPA (High-Efficiency Particulate Air) filters are required for asbestos due to their ability to capture fine fibers.
- Who is responsible for ensuring proper supervision and compliance at a job site? A. The building owner B. The project designer C. The licensed supervisor D. The waste transporter The licensed asbestos supervisor is responsible for site compliance and safety.
C. Increasing ventilation D. Burning the material Wet methods reduce airborne fiber release during asbestos removal.
- How often must air monitoring be done during a large asbestos project? A. Weekly B. At the end of the job C. Daily or as required by regulation D. Monthly Air monitoring ensures the environment remains safe during abatement, especially on a daily basis.
- What is glove bag technique used for? A. Large-scale ACM removal B. Small pipe insulation removal C. Spray applications D. Floor tile removal Glove bags are used for small-scale removal, especially pipe insulation.
- Decontamination units must include:
A. Drinking water station B. Equipment room, shower, and clean room C. Storage for tools D. Telephone booth A decon unit must have an equipment room, a shower, and a clean room to avoid contamination.
- What is a clearance air test? A. A check on HVAC efficiency B. A test to verify safe fiber levels post-abatement C. A random EPA audit D. A respiratory fit test Clearance air testing confirms fiber levels are below acceptable limits after work is completed.
- How should asbestos debris be disposed of? A. In plastic bags in regular trash B. Flushed down a drain C. In sealed, labeled containers at approved landfills D. Burned on-site
A. 8-hour awareness B. 40-hour EPA-approved supervisor course C. Online orientation D. First aid training only Supervisors must complete a 40-hour accredited asbestos contractor/supervisor course.

- Who conducts final visual inspection after abatement? A. The building owner B. The contractor C. The project monitor or competent person D. Waste transporter The project monitor performs visual inspection before clearance testing.
- A HEPA vacuum should be used to: A. Blow away fibers B. Remove fine asbestos dust safely C. Clean carpets D. Scrub floors Only HEPA vacuums can safely remove asbestos particles without dispersing them.
- What is the required number of air changes per hour (ACH) for negative pressure enclosures? A. 2 B. 8 C. 4 D. 10 Negative pressure enclosures must maintain at least 4 air changes per hour to control fiber levels.
- The function of the manometer during abatement is to: A. Record temperature B. Test humidity

C. TSCA
D. DOT CFR 49
OSHA 29 CFR 1926.1101 governs asbestos safety in construction work, including exposure limits.
- Before using a respirator, a worker must: A. Sign a waiver B. Undergo medical evaluation C. Fill out a logbook D. Submit their resume Medical evaluations are required to ensure workers are physically fit to wear respirators.
- Asbestos waste containers must be: A. Cardboard only B. Leak-tight and labeled C. Ventilated D. Reusable
Containers must be leak-tight and clearly labeled as containing asbestos waste.
- The purpose of the final visual inspection is to: A. Save on testing costs B. Ensure no visible debris remains before air testing C. Replace air monitoring D. Evaluate noise levels The final visual ensures the work area is visibly clean before clearance testing.
- A competent person is required to: A. Inspect only once B. Be on-call during work C. Be present and conduct frequent inspections D. Only review reports A competent person must oversee and regularly inspect asbestos abatement operations.
- Which of the following must be posted at the worksite?
OSHA enforces worker safety standards including those for asbestos.
- Asbestos fibers are most dangerous when: A. Sealed B. Encapsulated C. Airborne D. Painted Airborne asbestos fibers pose the greatest risk as they can be inhaled and lodged in lung tissue.
- When should glove bags be discarded? A. When filled with water B. After 24 hours C. Immediately after single use D. After final clearance Glove bags are designed for single use and should be discarded after removal.
