Q21/ 40
A precast concrete erection crew is installing tilt-up wall panels weighing 10,000 lbs each. The panels are 24 feet tall. Workers must climb onto the panel to release the rigging hook at the top after placement. The panel is temporarily braced. What fall protection is required for the workers releasing the rigging?
✅ Correct Answer: B
1926.501(b)(1) requires fall protection at 6+ feet for all construction work. There is no blanket exemption for precast concrete erection. 1926.501(b)(2)(i) allows a controlled access zone for leading edge work, but climbing a panel to release rigging is not leading edge work — it is direct exposure to a 24-foot fall. 1926.501(b)(12) specifically addresses precast concrete erection, requiring fall protection. Many tilt-up fatalities occur during panel release operations.
Q22/ 40
During inspection of a PFAS, a competent person finds that a 6-foot shock-absorbing lanyard has been subjected to a fall. The indicator stitching on the shock pack is fully deployed (torn open). The lanyard otherwise looks intact. What must be done?
✅ Correct Answer: B
1926.502(d)(19): personal fall arrest systems and components subjected to impact loading shall be immediately removed from service and shall not be used again for employee protection until inspected and determined by a competent person to be undamaged and suitable for reuse. However, for shock-absorbing lanyards with deployed tear-away indicators, manufacturers universally require immediate removal from service with no recertification option — the energy-absorbing element is sacrificial and cannot be reloaded. The lanyard must be destroyed or tagged out permanently.
Q23/ 40
A crew is doing overhand bricklaying from a supported scaffold. The scaffold platform height varies from 6 to 12 feet above grade. At the 12-foot section, workers are laying the top course of a wall. What height triggers additional fall protection requirements for overhand bricklaying?
✅ Correct Answer: B
1926.501(b)(9) provides a limited exception: employees engaged in overhand bricklaying and related work who are on a supported scaffold do not require guardrails or PFAS until the working surface reaches 10 feet or more. This is one of the few areas where OSHA allows a higher trigger height. However, at 10 feet and above, the employer must provide fall protection. Note that many state-plan states and collective bargaining agreements require fall protection at 6 feet regardless of this federal exception.
Q24/ 40
A worker is using a body belt (not a full-body harness) as part of a fall restraint system while working on a water tank roof at 25 feet. The belt prevents the worker from reaching the edge. An OSHA inspector sees this. What is the likely outcome?
✅ Correct Answer: A
1926.502(d)(17) prohibits the use of body belts as part of a personal fall ARREST system (effective January 1, 1998). However, body belts may still be used for fall RESTRAINT systems (preventing the worker from reaching a fall hazard) and work positioning systems. The distinction is critical: a fall arrest system catches a falling worker, while a fall restraint system prevents access to the hazard. The inspector would verify the system actually restrains the worker from reaching the edge before making a determination.
Q25/ 40
At a highway bridge project, workers are on a deck 50 feet above a river. The project requires fall protection. The general contractor installs a perimeter cable guardrail system with 1/2-inch steel cables: top cable at 42 inches, intermediate cable at 21 inches, posts at 8 feet. All cables are tensioned. Is this system compliant?
✅ Correct Answer: B
1926.502(b)(1) sets top rail height at 42 inches ±3 inches. 1926.502(b)(3) requires the top rail to withstand 200 lbs of force applied within 2 inches of the top edge in any outward or downward direction. Tensioned wire rope/cable guardrails are permitted, but they must meet the same deflection requirements. Under load, a tensioned cable can deflect significantly, potentially dropping below the 39-inch minimum. 1926.502(b)(9) specifically allows wire rope guardrails using correct gauge and with turnbuckle tensioning, but the 200-lb test still applies — the cable must not deflect below 39 inches under load.

Q26/ 40
Workers are on a commercial building roof removing old HVAC units. The roof edge is 38 feet above grade. A warning line is set 15 feet from all edges. Workers are not tied off. Is this compliant?
✅ Correct Answer: B
1926.501(b)(10) permits warning line systems specifically for roofing work on low-slope roofs (≤4:12 pitch). HVAC equipment removal is NOT roofing work — it falls under 1926.501(b)(1): general fall protection at 6+ feet. The 15-foot warning line distance rule under 1926.502(f)(1)(i) applies to mechanical equipment operations, but this does not exempt workers from fall protection when they are within 15 feet of the edge performing non-roofing tasks. Workers removing HVAC equipment near a 38-foot edge must use guardrails, safety nets, or PFAS.
Q27/ 40
A competent person is inspecting safety nets before installation. The nets were used on a previous project and stored in a dry warehouse. What is the minimum drop-test or certification requirement for reused safety nets?
✅ Correct Answer: A
1926.502(c)(4)(i): safety nets shall be drop-tested at the jobsite after installation and before being used, whenever relocated, after major repair, and at 6-month intervals if left in place. The drop test uses a 400-lb (180 kg) bag of sand 28-32 inches in diameter dropped from the highest walking/working surface. Alternatively, 1926.502(c)(4)(ii) allows certification by a qualified person in lieu of drop-testing, with the certification record maintained at the jobsite. Nets stored properly may degrade from UV exposure if previously used outdoors — storage conditions alone don't guarantee net integrity.
Q28/ 40
A worker on a communication tower at 180 feet is using a PFAS with a vertical lifeline. The rope grab (fall arrester) is installed upside down — the arrow points down instead of up. The foreman says 'it'll still catch.' What actually happens if the worker falls with an upside-down rope grab?
✅ Correct Answer: B
1926.502(d)(1) requires the employer to follow manufacturer instructions. Rope grabs are directional devices designed to lock when weight is applied in one direction only. The arrow indicates the 'up' or loading direction. Installed upside-down, the internal camming mechanism will not engage the lifeline under load — the device relies on the cam rotating against the rope in a specific orientation. The worker would experience a completely uncontrolled fall. This is a well-documented cause of fatalities in tower work.
Q29/ 40
A project has a written fall protection plan (FPP) that states conventional fall protection is infeasible for certain roof work and establishes a CAZ. The FPP was written by the on-site foreman who has 15 years experience but no engineering degree. Is the FPP valid?
✅ Correct Answer: B
1926.502(k)(1): the fall protection plan shall be prepared by a qualified person and developed specifically for the site where the work is being performed. A 'qualified person' under 1926.32(m) is defined as one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems related to the subject matter. While 15 years of experience could potentially qualify someone, the FPP must also be site-specific (1926.502(k)(1)) and must document the reasons why conventional fall protection is infeasible (1926.502(k)(2)).
Q30/ 40
Three workers are on a 24-foot high roof installing insulation. They are using PFAS with 6-foot lanyards anchored to a horizontal lifeline system. If all three workers fall simultaneously, what structural requirement applies to the horizontal lifeline?
✅ Correct Answer: B
1926.502(d)(15): anchorages used for attachment of PFAS shall support at least 5,000 lbs per employee attached, OR be designed, installed, and used as part of a complete PFAS which maintains a safety factor of at least two under the supervision of a qualified person. For a horizontal lifeline with three workers, the default requirement is 5,000 lbs × 3 = 15,000 lbs. However, if a qualified person (engineer) designs the system, the anchorage loads are calculated based on the number of workers, line tension, sag, and maximum arrest force, with a safety factor of 2 applied to the calculated loads.
