Read the first 7 High-Risk Activities flashcards as text

  1. What is the primary hazard when using a cartridge-operated fixing tool?

    Answer: The fixing or cartridge acting as a projectile if misused

    Cartridge-operated tools drive fixings at high velocity; improper use can cause the fixing or cartridge to become a dangerous projectile.

  2. Which regulation governs work at height in the United States construction industry?

    Answer: OSHA 1926 Subpart M — Fall Protection

    OSHA 29 CFR 1926 Subpart M sets the fall protection requirements for construction work, including guardrails, safety nets, and personal fall arrest systems.

  3. What must be done with a personal fall arrest system after it has arrested a fall?

    Answer: Remove it from service and have it inspected by the manufacturer or competent person before reuse

    After arresting a fall, a PFAS must be removed from service immediately because the components may be structurally compromised even if no visible damage is apparent.

  4. Which hazard is specifically associated with working on or near asbestos-containing materials during renovation?

    Answer: Inhalation of airborne asbestos fibers causing lung disease

    Disturbing asbestos-containing materials releases microscopic fibers that, when inhaled, can cause mesothelioma, asbestosis, and lung cancer.

  5. A crane operator receives conflicting signals from two signalers during a lift. What should the operator do?

    Answer: Stop the lift immediately and clarify with a single designated signaler

    Only one designated signaler should direct a lift; conflicting signals require an immediate stop until communication is clarified.

  6. What is a toolbox talk (TBT) designed to achieve on a high-risk construction site?

    Answer: Brief workers on specific hazards and safe methods for upcoming tasks

    Toolbox talks are short, informal briefings held before a task to communicate specific hazards, controls, and safe work methods relevant to that day's activities.

  7. When using a chainsaw on a construction site, what is the greatest risk if the tip of the bar contacts an object?

    Answer: Kickback, where the saw is thrown back violently toward the operator

    Kickback occurs when the tip of the chainsaw bar contacts a surface, causing the bar to rotate violently upward and backward toward the operator.
