  1. A construction crew is working on a bridge over a river. Which fall protection system is most appropriate when workers must move frequently along the structure?

    Answer: Self-retracting lifeline on a horizontal lifeline

    A self-retracting lifeline on a horizontal lifeline allows freedom of movement along the structure while maintaining continuous fall protection.

  2. Under OSHA 1926.502, what is the minimum distance a warning line must be set back from an unprotected edge on a low-slope roof?

    Answer: 6 feet

    Warning lines must be erected at least 6 feet from the roof edge under OSHA 1926.502(f)(2)(i) when used with other protective measures.

  3. What is the maximum allowable total fall distance (including deceleration distance and harness stretch) for a worker using a PFAS?

    Answer: 12 feet

    OSHA requires that a PFAS arrest a fall within 3.5 feet of deceleration distance, and total fall distance (free fall + deceleration + harness elongation) must not allow contact with a lower level — typically totaling no more than about 18.5 feet maximum.

  4. A covered floor opening is discovered on a job site without a hole cover. What immediate action should a supervisor take?

    Answer: Guard the opening immediately and install a proper cover or barricade

    OSHA 1926.502(i) requires floor holes to be guarded by a railing and cover immediately — the supervisor must act at once to prevent falls.

  5. Which type of anchorage point is the MINIMUM acceptable for attaching a personal fall arrest system under OSHA?

    Answer: A certified anchorage with 5,000-pound capacity per attached worker

    OSHA 1926.502(d)(15) requires PFAS anchors to support at least 5,000 pounds per worker attached, or be designed by a qualified person with a 2:1 safety factor.

  6. When inspecting a body harness before use, a worker finds a frayed strap on the dorsal D-ring connection. What should the worker do?

    Answer: Tag the harness out of service and notify the supervisor

    Any defective or damaged PFAS component must be immediately removed from service and tagged, as it cannot be trusted to arrest a fall safely.

  7. What is the OSHA requirement for the top rail height of a guardrail system on a construction site?

    Answer: 42 inches, plus or minus 3 inches

    OSHA 1926.502(b)(1) requires guardrail top rails to be 42 inches (±3 inches) above the walking or working surface.
