Which law outlines the Army's responsibilities under OSHA as a federal agency?

The correct answer is found in the first choice, as it refers to the specific regulation that outlines the Army's responsibilities under the Occupational Safety and Health Administration (OSHA) guidelines as a federal agency. The code 29 CFR 1960.8 provides a framework for federal agencies, including the Army, on how to comply with occupational safety and health standards established by OSHA. This regulation delineates the responsibilities of federal departments to create and maintain safe working environments for their employees.

Understanding this regulation is crucial for comprehending how the Army and other federal entities must implement safety and health standards to protect their personnel. The formulation of the regulation ensures that the Army's actions align with federal safety mandates, which are critical for workplace safety and adherence to legal requirements.
