Which agency is responsible for enforcing commercial workplace safety and environmental health regulations?

The Occupational Safety and Health Administration (OSHA) is the agency responsible for enforcing workplace safety regulations in commercial environments. OSHA's primary function is to ensure safe and healthful working conditions by setting and enforcing standards, as well as providing training, outreach, education, and assistance to employers and employees. This includes regulations aimed at reducing workplace hazards, preventing work-related injuries, illnesses, and fatalities.

In contrast, the Environmental Protection Agency (EPA) focuses more on protecting human health and the environment by overseeing regulations related to air and water quality, hazardous waste, and other environmental issues. The National Institute for Occupational Safety and Health (NIOSH) conducts research and provides recommendations to OSHA but does not enforce regulations directly. The term Safety and Health Administration (SHA) may refer to state-level agencies that vary in function but are not the primary federal authority like OSHA, which has comprehensive regulatory power in workplace safety at the national level.
