  1. A demolition supervisor is overseeing the removal of floor tiles installed in 1975. Under what regulatory framework must the supervisor assess and manage these tiles?

    Answer: OSHA 1926.1101, as they are assumed to contain asbestos (PACM)

    Floor tiles installed before 1981 are presumed asbestos-containing material (PACM) under OSHA 1926.1101 until tested and confirmed otherwise.

  2. What is the correct term for the zone immediately surrounding a hazmat incident during demolition, where only trained responders in full protective equipment are allowed?

    Answer: Hot zone

    The hot zone (exclusion zone) is the area of highest contamination where only trained responders with full PPE are permitted.

  3. Which confined space classification applies to a basement demolition area with a single ladder entry point and potential for toxic gas accumulation from disturbed materials?

    Answer: Permit-required confined space

    A space with restricted entry and a recognized serious safety or health hazard, such as toxic gas accumulation, qualifies as a permit-required confined space under OSHA 1910.146.

  4. What is the primary purpose of wetting down debris during building demolition?

    Answer: To suppress dust and reduce airborne particulate hazards

    Wetting debris is a primary engineering control for dust suppression, reducing airborne silica, asbestos fibers, and other particulates.

  5. Under SARA Title III (EPCRA), which report must a demolition site submit if they discover and release a listed extremely hazardous substance above the reportable quantity?

    Answer: Emergency release notification to the LEPC and SERC

    EPCRA Section 304 requires immediate emergency release notification to the Local Emergency Planning Committee (LEPC) and State Emergency Response Commission (SERC).

  6. Which type of fall protection system is generally preferred over personal fall arrest systems in demolition work when feasible?

    Answer: Guardrail systems

    Guardrail systems are a passive fall protection method preferred over personal fall arrest systems because they protect all workers without requiring individual action.

  7. What action must be taken if a demolition worker is found to have a blood lead level (BLL) at or above 60 μg/dL?

    Answer: Immediately remove the worker from lead exposure until BLL drops below 40 μg/dL

    OSHA 1926.62 requires medical removal of any worker with a BLL at or above 60 μg/dL, with return permitted only when BLL drops below 40 μg/dL.
