A certified safety official observes workers on a scaffold without guardrails at 12 feet above the ground. Which OSHA standard applies and what is the minimum guardrail height required?
Answer: 1926.451 — 42 inches
OSHA 1926.451 governs scaffold safety and requires toprails at least 38 inches high, but the standard specifies 42 inches as the requirement under 1926.451(g)(4)(ii).
Under OSHA's confined space standard for construction (29 CFR 1926 Subpart AA), what must a permit-required confined space entry program include?
Answer: Hazard identification, testing, entry permits, rescue procedures, and attendant duties
A permit-required confined space program must address hazard identification, atmospheric testing, written entry permits, rescue provisions, and attendant and entrant duties.
Which tool is used on construction sites to ensure workers are protected from being struck by vehicles operating in the same area?
Answer: Exclusion zones with physical barricades and spotters
Struck-by vehicle hazards are controlled through a combination of exclusion zones, physical barriers, spotters, and high-visibility PPE to separate workers from moving equipment.
What is the OSHA-required minimum illumination level (in foot-candles) for construction areas where general construction work is performed?
Answer: 5 foot-candles
OSHA 1926.56 requires a minimum of 5 foot-candles of illumination for general construction areas, corridors, hallways, and exitways.
When conducting a contractor safety audit on a construction site, which metric best indicates leading (proactive) safety performance?
Answer: Number of near-miss reports submitted
Near-miss reporting is a leading indicator because it reflects proactive hazard identification before injuries occur, unlike lagging indicators such as TRIR or DART.
Under OSHA's construction standards, which of the following is NOT a required component of a fall protection plan when conventional fall protection is infeasible?
Answer: Signatures from all workers covered by the plan
OSHA does not require individual worker signatures on a fall protection plan; the plan must identify operations, designate a safety monitor, and document why conventional protection is infeasible.
