Q1/ 40
A safety manager walks a 4-story commercial building under construction. On the third floor, workers are setting curtain wall panels 15 inches from the floor edge. The floor is 32 feet above grade. What fall protection is required?
✅ Correct Answer: C
29 CFR 1926.501(b)(1): any unprotected side or edge 6 feet or more above a lower level requires conventional fall protection (guardrail, safety net, or PFAS). There is no 'distance from edge' exemption — proximity to the hazard, not distance from it, triggers the requirement. 15 inches from a 32-foot fall is an imminent danger without protection.
Q2/ 40
A framing crew is sheathing a roof with a 6:12 pitch (26.5°) on a single-family home. The eave height is 22 feet. The foreman wants to use a safety monitoring system alone. Is this compliant?
✅ Correct Answer: C
1926.501(b)(10) allows a warning line + safety monitor combination ONLY for low-slope roofs (≤4:12 pitch). A 6:12 pitch is a steep roof under 1926.501(b)(11), requiring guardrails, safety nets, or PFAS. OSHA rescinded the residential construction exemption in 2011 — there is no residential exception for fall protection.
Q3/ 40
A concrete formwork crew is stripping forms on the edge of an elevated deck. The workers are using a job-built guardrail. The top rail is a single 2×4 at 38 inches above the deck. Is this compliant?
✅ Correct Answer: B
1926.502(b)(1): top rail height must be 42 inches ±3 inches (range: 39-45 inches). 38 inches is below the minimum. Additionally, 1926.502(b)(3) requires the top rail to withstand 200 lbs of force applied within 2 inches of the top edge. A single horizontal 2×4 may not meet this strength requirement depending on post spacing.
Q4/ 40
During steel erection, a connector is working at a column 55 feet above grade. The column has no floor or decking nearby — just the steel frame. The worker is using a personal fall arrest system. What is the maximum allowable free fall distance?
✅ Correct Answer: B
1926.502(d)(16)(iii): personal fall arrest systems must be rigged so an employee cannot free fall more than 6 feet (1.8 m) nor contact any lower level. The deceleration distance (typically 3.5 feet) plus harness stretch must be accounted for in total clearance calculations. At 55 feet, the anchorage point height must ensure total fall distance stays within these limits.
Q5/ 40
A construction crew installs a safety net system 25 feet below a steel erection work area. The net extends 8 feet horizontally beyond the work area on all sides. Is this installation compliant with 29 CFR 1926.502(c)?
✅ Correct Answer: C
1926.502(c)(1): safety nets must be installed as close as practicable under the walking/working surface, but never more than 30 feet below. 25 feet is within this limit. However, 1926.502(c)(2) requires nets to extend outward a minimum distance based on fall distance — for 25 feet vertical, the required horizontal distance is greater than 8 feet. Additionally, 1926.502(c)(2) specifies net mesh size must not exceed 6 inches × 6 inches.

Q6/ 40
A foreman discovers three employees working on a flat commercial roof (2:12 pitch) at 28 feet. The roof perimeter has no guardrail. The foreman sets up a warning line 6 feet from the edge and designates a safety monitor. No other fall protection is provided. Is this compliant?
✅ Correct Answer: B
1926.501(b)(10) permits a warning line system in combination with a safety monitor for low-slope roofing work (≤4:12 pitch). BUT 1926.502(f)(1)(ii) requires the warning line be erected not less than 6 feet from the roof edge for roofing work — wait, the standard actually says 6 feet. However, 1926.502(f)(1) says warning lines for roofing must be at least 6 feet from the edge. So actually A is correct IF the 6-foot distance is met AND a safety monitor is present AND the roof pitch is ≤4:12. But wait — the standard also says the warning line must be flagged every 6 feet. Let me re-read: 1926.502(f)(1)(i): 'The warning line shall be erected not less than 6 feet (1.8 m) from the roof edge.' So the minimum is 6 feet, meaning both A and B could be correct depending on interpretation. Option A is actually the correct answer — the 15-foot rule is for mechanical equipment, not general roofing.
Q7/ 40
A project superintendent orders a fall protection anchor to be installed on a concrete column using an expansion bolt rated at 4,500 lbs. The anchor will serve one worker's PFAS. Is this anchor compliant with OSHA requirements?
✅ Correct Answer: B
1926.502(d)(15): anchorages for personal fall arrest equipment must be independent of any anchorage used to support or suspend platforms AND must support at least 5,000 lbs (22.2 kN) 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. 4,500 lbs does not meet the 5,000 lb default requirement.
Q8/ 40
During an OSHA inspection, a compliance officer observes a hole cover on a concrete floor labeled 'HOLE — DO NOT REMOVE'. The cover is a piece of 1/2-inch plywood placed over a 2-foot × 2-foot floor opening, not secured. Workers walk past it regularly. What violation exists?
✅ Correct Answer: B
1926.502(i)(1): hole covers must be capable of supporting at least twice the weight of employees, equipment, and materials that may be imposed on them. 1926.502(i)(3): covers must be secured when installed to prevent accidental displacement by wind, equipment, or employees. Additionally, 1926.501(b)(4)(i) requires every employee on walking/working surfaces be protected from falling through holes more than 6 feet above lower levels. An unsecured 1/2-inch plywood cover over a 2-foot opening fails both the securing and strength requirements.
Q9/ 40
A bridge construction crew is working on a pier cap 80 feet above water. Two workers are using 6-foot lanyards with deceleration devices, anchored at foot level on the formwork. The calculated total fall distance including deceleration and harness stretch is 18.5 feet. There is a lower crossbeam 16 feet below the work surface. Is this PFAS configuration acceptable?
✅ Correct Answer: B
1926.502(d)(16)(iii): PFAS must be rigged to prevent the employee from free falling more than 6 feet nor contacting any lower level. The total fall clearance calculation = free fall distance + deceleration distance + harness stretch + safety factor. With foot-level anchorage, the free fall can be up to 12 feet (worker height above anchor), plus 3.5 feet deceleration, plus 1 foot stretch = 16.5+ feet. At 18.5 feet calculated, and only 16 feet clearance, the worker would strike the crossbeam — a potentially fatal impact. The anchorage must be raised or a shorter lanyard used.
Q10/ 40
At a multi-employer worksite, a masonry subcontractor removes a section of perimeter guardrail to land pallets of brick on the 5th floor. The general contractor's superintendent sees this but takes no action. An OSHA inspector arrives. Who is citable?
✅ Correct Answer: C
Under OSHA's Multi-Employer Citation Policy (CPL 02-00-124), the exposing employer (masonry sub — whose employees are exposed) AND the controlling employer (general contractor — who has authority to correct hazards) can both be cited. 1926.501(b)(1) requires fall protection at 6+ feet. The GC superintendent's failure to act despite knowledge of the violation constitutes a failure of the controlling employer's duty. This is one of the most common citations in construction — the GC is almost always responsible for site-wide hazards they could reasonably detect and correct.
