Which department enforces OSHA standards across all states?

The Department of Labor is responsible for enforcing Occupational Safety and Health Administration (OSHA) standards across all states. OSHA was created under the Occupational Safety and Health Act of 1970, which is administered by the Department of Labor. This department oversees the implementation of health and safety regulations designed to protect workers in various industries, ensuring that employers comply with safety standards to reduce workplace hazards and prevent occupational injuries and illnesses.

The other departments mentioned do not have a primary role in enforcing workplace safety regulations. The Department of Energy focuses on policies related to energy production and regulation, the Department of the Interior manages natural resources and federal lands, and the Environmental Protection Agency primarily deals with environmental protection and regulations related to pollution control. Therefore, the Department of Labor is the correct entity for the enforcement of OSHA standards across the nation.
