Q31/ 40
A crane is hoisting workers in a suspended personnel platform to access a bridge inspection point 120 feet above water. The platform is suspended from the crane's load line. In addition to the platform guardrails, what personal fall protection must each worker in the platform use?
✅ Correct Answer: B
1926.1431(k): each employee on a personnel platform being hoisted by a crane must be protected by a PFAS, and the fall arrest system must be anchored to a designated point on the platform or a point above the platform — NOT to the crane's load line or hook. 1926.502(d)(15) requires the anchorage to support 5,000 lbs per attached employee. The platform's guardrail system provides secondary protection but the PFAS is the primary fall protection for suspended personnel platform operations.
Q32/ 40
A foreman on a residential construction project (single-family home, 22-foot eave height) decides that conventional fall protection (guardrails, safety nets, PFAS) is infeasible because the crew needs to move quickly across the roof. The foreman writes a fall protection plan designating a safety monitoring system and warning lines. Is this legally acceptable?
✅ Correct Answer: B
1926.502(k)(2) requires the FPP to document the reasons why the use of conventional fall protection is infeasible. 'Infeasible' means it is functionally impossible to use conventional fall protection OR its use would create a greater hazard. Productivity concerns, cost, speed, and convenience do not constitute infeasibility under OSHA interpretation. OSHA compliance directives consistently reject these arguments. The FPP exception is narrow and must demonstrate that the specific structural conditions make conventional protection impossible to use, not merely inconvenient.
Q33/ 40
A crew is working on a 10:12 pitch roof (steep roof) at 20 feet. The foreman installs roof brackets with 2×10 planks as a working platform. The planks are not secured to the brackets. Workers are walking and kneeling on the planks. In addition to PFAS, what is wrong with this setup?
✅ Correct Answer: B
1926.501(b)(11) requires conventional fall protection on steep roofs. Roof bracket scaffolds are regulated under 1926.452(j): brackets must fit the roof angle and be securely fastened. The planks forming the platform must comply with 1926.451(a): scaffold planking must be secured against displacement. Unsecured planks on brackets can kick out or slide, causing the worker to lose footing on a steep roof. Additionally, 1926.451(a)(1) requires each platform to be fully planked and decked.
Q34/ 40
A construction safety manager discovers that the project's only rescue plan for suspended workers is 'call 911.' The project involves bridge work where workers are suspended 150 feet above a river. Response time for the local fire department's technical rescue team is estimated at 45 minutes. Is this rescue plan compliant?
✅ Correct Answer: B
1926.502(d)(20): the employer shall provide for prompt rescue of employees in the event of a fall or shall assure that employees are able to rescue themselves. 'Prompt' is generally interpreted as 6 minutes or less due to suspension trauma risk. Suspension trauma (orthostatic intolerance) can onset within minutes when a person hangs motionless in a harness — blood pools in the legs, causing unconsciousness and potentially death. OSHA Technical Manual Section V, Chapter 4 details suspension trauma risks. A 45-minute 911 response is insufficient. The employer must have a self-rescue capability (e.g., descent devices) or on-site rescue capability.
Q35/ 40
On a 20-story building construction project, a debris net is installed at the 4th floor level (approximately 48 feet above grade) to catch falling tools and materials. The net extends 12 feet outward from the building face. Is this debris net also acceptable as a personnel safety net?
✅ Correct Answer: B
1926.502(c)(2): safety nets for personnel must have mesh openings not exceeding 6 inches × 6 inches (36 sq in). Debris nets typically have much larger mesh. The key difference is STRENGTH. 1926.502(c)(4) requires a 400-lb drop test for personnel nets. 1926.502(c)(8) specifies that defective nets must be removed from service. The two net types serve different purposes and are not interchangeable — debris nets are for falling OBJECT protection (1926.451(h)(4)(iv)), while personnel safety nets are for falling PERSON protection under 1926.502(c).

Q36/ 40
A painter is using a boatswain's chair (suspended seat) to access the exterior of a 5-story building. The chair is suspended by a single rope with a descent control device. What personal fall protection is required in addition to the chair's suspension system?
✅ Correct Answer: B
1926.451(g)(1)(ii): employees on a boatswain's chair must be protected by a personal fall arrest system. 1926.502(d)(15) requires the PFAS anchorage to be independent of the work platform support — meaning a separate lifeline from the suspension rope. If the suspension rope fails, the PFAS catches the worker. This is analogous to suspended scaffold requirements under 1926.451(g)(1)(vii). Many boatswain's chair fatalities involve reliance on a single rope as both work support and fall protection.
Q37/ 40
During a structural steel erection project, a connector is working on beams at 35 feet. Under 29 CFR 1926.760 (Subpart R — Steel Erection), at what height must the connector use fall protection?
✅ Correct Answer: B
1926.760(b)(1): connectors must be provided with fall protection at heights over 15 feet (or over 30 feet for connectors working on a controlled decking zone under 1926.760(c)). This is a Subpart R-specific higher threshold compared to the 6-foot general trigger under Subpart M. However, 1926.760(a)(1) requires fall protection at 15 feet for all other steel erection activities (deckers, bolters, welders). Steel erection has its own fall protection standard (Subpart R) that takes precedence over Subpart M.
Q38/ 40
A worker is issued a full-body harness for use on a 3-month bridge painting project. The harness is worn daily, exposed to paint overspray, UV radiation, and sweat. The manufacturer's instructions say 'inspect before each use' but give no specific inspection criteria. What is the minimum acceptable inspection protocol?
✅ Correct Answer: B
1926.502(d)(21): personal fall arrest systems shall be inspected prior to each use for wear, damage, and other deterioration, and defective components shall be removed from service. ANSI Z359.2 provides detailed inspection criteria including checking webbing for cuts (more than 1/8 inch requires removal), chemical damage (stiff or softened areas), UV degradation (faded or brittle webbing), stitching (pulled or cut threads), and hardware (cracks, corrosion, deformation). For projects involving paint overspray, harnesses should be cleaned according to manufacturer instructions — chemicals in paint can degrade nylon/polyester webbing.
Q39/ 40
A guardrail system is being built around a floor opening that measures 3 feet × 3 feet. The opening will be used as a material hoisting shaft for 2 weeks before being filled. Two sides of the opening are adjacent to walls. What guardrail configuration is required?
✅ Correct Answer: A
1926.501(b)(4)(i): each employee on a walking/working surface shall be protected from falling through holes more than 6 feet above lower levels. 1926.502(b)(11): guardrail systems around holes shall be erected on all unprotected sides or edges. While walls adjacent to 2 sides might provide some protection, OSHA interprets 'unprotected' broadly — material hoisting means active work around the hole, and a worker could fall from the sides adjacent to walls. Additionally, 1926.501(b)(4)(ii) requires protection from tripping or stepping into holes — a guardrail on all open sides plus the wall-adjacent sides is the safest practice.
Q40/ 40
A commercial roofing crew of 8 workers is on a 2:12 pitch roof, 30 feet eave height, doing a full tear-off and replacement. The foreman uses a warning line at 6 feet and designates ONE safety monitor for all 8 workers spread across 3,000 sq ft of roof. The monitor stands at one corner of the roof. Is this adequate?
✅ Correct Answer: B
1926.502(h)(1)(iv): the safety monitor must be positioned to be within visual sighting distance of the employees being monitored. 1926.502(h)(1)(iii): the safety monitor must be able to identify fall hazards and warn employees. With 8 workers across 3,000 sq ft and one monitor at a corner, workers on the far side of the roof are out of visual range. The monitor must also be on the same walking/working surface (1926.502(h)(1)(i)). Multiple monitors or smaller work zones would be required for adequate coverage.
