What is the federal agency in charge of workplace safety called?

The federal agency responsible for workplace safety is known as OSHA, which stands for the Occupational Safety and Health Administration. OSHA was established to ensure safe and healthy working conditions for employees across various industries. It sets and enforces standards, provides training and education, and offers compliance assistance to help employers create safer workplaces.

NIOSH, while related to workplace safety, primarily focuses on research and recommendations rather than enforcement. The EPA, or Environmental Protection Agency, is concerned with environmental protection, while the FDA, or Food and Drug Administration, oversees the safety of food and pharmaceutical products. Thus, OSHA is the specific agency dedicated to the enforcement and promotion of workplace safety standards, making it the correct answer.
