Which organization is responsible for setting and enforcing workplace safety standards?

The Occupational Safety and Health Administration (OSHA) is responsible for setting and enforcing workplace safety standards. 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 establishing guidelines that employers must follow. This includes creating regulations, conducting inspections, and providing training and outreach to help employers and workers understand their rights and responsibilities regarding workplace safety.

The other organizations mentioned have different areas of focus; for instance, the Environmental Protection Agency (EPA) is primarily concerned with protecting human health and the environment. The Department of Labor oversees various aspects of employment law and workforce issues but does not specifically govern workplace safety standards in the same capacity as OSHA. The Federal Bureau of Investigation (FBI) deals with federal criminal investigations and security matters, which are unrelated to workplace safety standards. Therefore, OSHA is the designated authority for this specific aspect of workplace regulations.
