Explanation: OSHA, part of the U.S. Department of Labor, sets and enforces the construction safety standards found in 29 CFR 1926. NIOSH conducts research and makes recommendations but does not enforce standards, and the EPA and MSHA regulate different areas.

Explanation: The General Duty Clause requires each employer to furnish a place of employment free from recognized hazards that are causing or likely to cause death or serious physical harm. It is used when no specific standard applies. The other options are not requirements of this clause.

Explanation: The hierarchy of controls ranks elimination as the most effective method because it removes the hazard entirely. Substitution, engineering controls, administrative controls, and PPE follow in decreasing order of effectiveness, with PPE considered the last line of defense.

Explanation: Under OSHA's multi-employer citation policy, the creating employer is the one that caused a hazardous condition and can be cited even if only another contractor's workers are exposed. Controlling, exposing, and correcting employers each have separate, defined responsibilities.
