Which organization is responsible for regulating worker safety in the US?

The Occupational Safety and Health Administration (OSHA) is the federal agency responsible for regulating worker safety in the United States. Established under the Occupational Safety and Health Act of 1970, OSHA's primary mission is to ensure safe and healthy working conditions for employees by setting and enforcing standards, providing training, outreach, education, and assistance. The agency develops regulations that employers must follow to reduce workplace hazards, conduct inspections to enforce compliance, and provide resources to help organizations improve workplace safety protocols.

While other organizations listed may deal with aspects of labor and environmental safety, OSHA specifically focuses on the safety and health of workers. The National Institute of Standards and Technology, for example, primarily involves itself with standards and measurement, rather than directly addressing worker safety. The Environmental Protection Agency deals primarily with environmental protection rather than worker safety in the workplace. The Department of Labor oversees a broader range of issues, including labor standards and employment, but does not specifically regulate workplace safety, which is the exclusive responsibility of OSHA.
