  1. Which of the following is NOT a required component of a personal fall arrest system (PFAS)?

    Answer: Safety net as backup

    A PFAS consists of an anchorage, body harness, and connecting means; a safety net is a separate fall protection system, not a required component of a PFAS.

  2. After a personal fall arrest system has arrested a fall, what must happen before it is returned to service?

    Answer: Remove it from service and have it inspected by the manufacturer or a qualified person

    Any PFAS that has arrested a fall must be removed from service immediately and inspected by the manufacturer or a qualified person before it can be reused.

  3. When must an employer conduct a hazard assessment for walking-working surfaces under 29 CFR 1910.22?

    Answer: Regularly and as needed when conditions change

    OSHA 1910.22(d) requires employers to regularly and as needed inspect walking-working surfaces for hazardous conditions and correct or guard against any hazards found.

  4. A worker on a fixed ladder equipped with a personal fall arrest system experiences a free-fall. What is the maximum permissible free-fall distance allowed by OSHA?

    Answer: 6 feet

    OSHA 1910.140(c)(2) limits the free-fall distance in a PFAS to 6 feet, and the total fall distance including deceleration must not allow the worker to contact a lower level.

  5. Which of the following surfaces would be considered a 'walking-working surface' under the OSHA definition?

    Answer: Any horizontal or vertical surface on or through which an employee walks, works, or gains access

    OSHA 1910.21 broadly defines a walking-working surface as any horizontal or vertical surface on or through which an employee walks, works, or gains access, including floors, roofs, ramps, bridges, and similar surfaces.

  6. An outdoor loading dock surface becomes slippery due to ice. What is the employer's PRIMARY obligation under OSHA's walking-working surfaces standard?

    Answer: Ensure the surface is maintained in dry or slip-resistant condition or provide slip-resistant footwear

    OSHA 1910.22(a)(2) requires employers to keep walking-working surfaces free of ice, snow, and other slip hazards, or otherwise provide equivalent protection such as slip-resistant surfaces or footwear.

  7. What is the minimum toe-board height required by OSHA on elevated platforms where a falling-object hazard exists?

    Answer: 4 inches

    OSHA 1910.29(h)(1) requires toe boards to be a minimum of 3.5 inches tall; however, OSHA's general industry standard specifies at least 3.5 inches with 4 inches being the common accepted standard.
