Which federal agency is responsible for administering OSHA regulations?

The United States Department of Labor is the federal agency responsible for administering OSHA regulations. This department oversees the implementation of the Occupational Safety and Health Administration, which is charged with ensuring safe and healthy working conditions for workers by setting and enforcing standards as well as providing training, outreach, education, and assistance. The Department of Labor plays a crucial role in formulating policies related to labor standards and workplace safety, making it the primary authority concerning OSHA regulations.

Other agencies mentioned in the choices, such as the Environmental Protection Agency, focus on environmental protection and regulation rather than workplace safety. Similarly, the United States Army Corps of Engineers deals primarily with engineering projects and public works, not labor regulations. The Occupational Safety and Health Review Commission does play a role in adjudicating disputes regarding OSHA citations, but it does not administer regulations; rather, it serves as a judicial body in the context of OSHA's enforcement efforts.
