Q11/ 40
A window installer on a 40-story high-rise is working from a suspended scaffold when the primary support rope begins to fray. The installer is wearing a full-body harness with a 6-foot lanyard. Where must the lanyard be anchored?
✅ Correct Answer: B
1926.502(d)(15) requires PFAS anchorages to be independent of any anchorage used to support or suspend platforms. Attaching to the scaffold itself means if the suspension fails, the worker falls with the scaffold. An independent vertical lifeline (separate from the scaffold's support lines) is the only compliant option. 1926.451(g)(1)(vii) specifically requires personal fall arrest systems used on suspended scaffolds to be attached to a vertical lifeline or to a structural member capable of supporting 5,000 lbs.
Q12/ 40
A construction site has a large skylight opening (4 ft × 8 ft) on a flat roof 25 feet above grade. Workers regularly walk past it during HVAC maintenance. The foreman places orange warning cones around it. Is this compliant?
✅ Correct Answer: B
1926.501(b)(4)(i) treats skylights as holes — employees must be protected from falling through them by covers, guardrails, or PFAS. 1926.502(i)(1) requires covers to support at least twice the maximum intended load. Warning cones do not physically prevent a fall — a worker backing up or distracted could easily step into the skylight. Skylight falls account for a significant percentage of roofing fatalities annually.
Q13/ 40
An ironworker is connecting steel beams on a bridge project. The worker is using a 6-foot shock-absorbing lanyard attached to a horizontal lifeline at shoulder height. If the worker falls, what is the approximate free fall distance before the deceleration device begins to engage?
✅ Correct Answer: C
When anchored at shoulder height, a 6-foot lanyard attached to the back D-ring will allow the worker to fall approximately the full length of the lanyard before the deceleration device engages, plus the distance from the D-ring to the anchor. The free fall is roughly 6 feet because the anchor is at the same height as the D-ring and the lanyard must straighten out. 1926.502(d)(16)(iii) limits maximum free fall to 6 feet. Anchoring overhead (above the D-ring) reduces free fall distance significantly and should always be preferred.
Q14/ 40
A roofing crew is working on a 3:12 pitch metal roof at 20 feet. The foreman installs a warning line system at 6 feet from the edge and assigns a safety monitor who is also responsible for passing materials to the crew. Is this compliant?
✅ Correct Answer: B
1926.502(h)(1)(v): the safety monitor must have no other duties that take attention away from the monitoring function. Passing materials is a competing duty that would distract the monitor from watching the crew. Additionally, 1926.502(h)(1)(i) requires the safety monitor to be on the same walking/working surface as the crew and within visual sighting distance. The 3:12 pitch (≤4:12) makes the warning line + monitor system an allowable method under 1926.501(b)(10), but only if all 1926.502(h) requirements are met.
Q15/ 40
During demolition of a 6-story building, a controlled access zone (CAZ) is established for the leading edge on the 4th floor. The CAZ is marked by a control line at 6 feet from the edge. A new worker enters the CAZ without fall protection. Who is permitted inside the CAZ without a PFAS?
✅ Correct Answer: B
1926.502(k)(5): only employees engaged in leading edge work under 1926.501(b)(2)(i) are permitted inside the controlled access zone. The CAZ designation does not eliminate fall hazards — it restricts access to trained, designated workers. 1926.502(k)(7) states that access to the CAZ is limited to those employees covered by the fall protection plan. The control line must be flagged at 6-foot intervals, and 1926.502(k)(4) requires the CAZ to be clearly marked.

Q16/ 40
A cell tower technician is climbing a 300-foot monopole using a positioning system (work positioning belt with pole strap). At 150 feet, the technician must transition to a different climbing path. During the transition, the worker disconnects one connector. What fall protection method is required during the transition?
✅ Correct Answer: B
1926.502(d)(16)(iii) requires PFAS to limit free fall to 6 feet. During climbing transitions on communication towers, OSHA expects 100% tie-off — meaning the climber must always have at least one connection point engaged. Double lanyards (twin-leg lanyards or Y-lanyards) allow the climber to attach the second lanyard before disconnecting the first. OSHA has issued specific guidance for communication tower work emphasizing 100% fall protection at all times.
Q17/ 40
A construction crew is pouring concrete for the 10th floor deck of a high-rise. Workers must access the perimeter formwork. The general contractor installs a guardrail system with steel posts at 8-foot intervals, a 2×4 top rail at 42 inches, and no midrail. A worker stumbles and nearly falls between the top rail and the deck. What is missing?
✅ Correct Answer: B
1926.502(b)(2): guardrail systems must have a midrail, screen, mesh, intermediate vertical members, or equivalent structural members installed between the top rail and the walking/working surface when there is no wall or parapet wall at least 21 inches high. The midrail must be installed approximately halfway between the top rail and the walking surface. A worker can easily fall through the gap between a 42-inch top rail and the deck without intermediate protection.
Q18/ 40
A residential roofing crew of 4 workers is installing shingles on a 8:12 pitch roof at 18 feet eave height. The foreman provides each worker with a PFAS but only one worker uses it — the other three refuse, saying it slows them down. OSHA inspects. The employer has a written fall protection plan but it was written 3 years ago for a different project. What is the employer's liability?
✅ Correct Answer: B
1926.501(b)(11) requires fall protection on steep roofs. 1926.503(a)(1) requires the employer to provide a training program for each employee who might be exposed to fall hazards. The employer's duty goes beyond providing equipment — 1926.21(b)(2) requires the employer to instruct each employee in the recognition and avoidance of hazards. OSHA consistently cites employers who fail to enforce fall protection use, even when equipment is available. An outdated fall protection plan not specific to the current project also fails to meet 1926.502(k)(1) requirements.
Q19/ 40
On a wind turbine construction site, a crew is working inside the nacelle 280 feet above ground. The only access is an internal ladder with a cable fall arrest system. A new worker weighs 310 lbs including tools. What is required before the worker can use the ladder fall arrest system?
✅ Correct Answer: B
1926.502(d)(16)(ii) requires the PFAS to limit maximum arresting force to 1,800 lbs (8 kN) for a body harness. However, the equipment must be rated for the user's actual weight. ANSI Z359.6 requires that fall protection equipment be selected considering the total weight of the user including tools and clothing. If the system was designed for a 310-lb maximum capacity, it must be verified. Standard equipment typically has a capacity range of 130-310 lbs. Additionally, 1926.502(d)(15) requires anchorages to support 5,000 lbs.
Q20/ 40
A worker on a 10-story building under construction is using a retractable lifeline (SRL) anchored at foot level on a concrete column. The manufacturer's instructions specify the SRL must be anchored at or above the D-ring level. The foreman says 'an anchor is an anchor.' What is the actual concern?
✅ Correct Answer: B
1926.502(d)(16)(iii) requires the system to prevent contact with lower levels. Foot-level anchorage of an SRL dramatically increases free fall distance because the cable must pay out before the inertial locking mechanism engages. A Class A SRL locks within 24 inches; Class B within 54 inches. Plus, the sag angle creates a swing fall hazard if the worker falls sideways. Following manufacturer instructions is required under 1926.502(d)(2): 'The employer shall provide for the proper use, inspection, maintenance, and storage of personal fall arrest systems in accordance with the manufacturer's instructions.'
