Which OSHA regulation governs safety practices during steel erection on construction sites?

• A. 29 CFR 1926 Subpart S (Steel Erection)
• B. 29 CFR 1910 Subpart R (Construction Safety)
• C. 29 CFR 1926 Subpart R (Steel Erection)
• D. 29 CFR 1926 Subpart M (Materials Handling)

Answer: (C)

The main concept tested is identifying the OSHA regulation that specifically governs steel erection activities on construction sites. The safety practices for erecting steel are addressed in the Construction standards, under a dedicated subpart that focuses on the hazards and required controls for steel erection—this is 29 CFR 1926 Subpart R. It covers what employers and workers must do to safely hoist, rig, bolt, and assemble steel structures, including fall protection, crane and rigging operations, and related site controls tailored to steel erection work.

Why this is the best answer: Subpart R within 1926 is designed specifically for steel erection, so it provides the targeted safety rules that apply to the unique risks of constructing steel frames on site. The other options either belong to different contexts (for example, general electrical safety on construction sites or materials handling under other subparts) or belong to general industry standards that don’t address the on-site steel erection practices in construction.
