What agency is responsible for enforcing safety work rules in the United States?

The Occupational Safety and Health Administration (OSHA) is the agency specifically responsible for enforcing safety work rules in the United States. OSHA was established to ensure safe and healthy working conditions for workers by setting and enforcing standards, providing training, outreach, education, and compliance assistance. This mission directly focuses on workplace safety and health regulations, making OSHA the primary entity in enforcing laws related to occupational safety.

While other agencies such as the Environmental Protection Agency (EPA), National Labor Relations Board (NLRB), and the Department of Labor (DOL) have significant roles in their respective areas—like environmental protection, labor relations, and broader labor policies—they do not primarily focus on the enforcement of workplace safety rules. Therefore, OSHA stands out as the dedicated authority for maintaining safety standards in workplaces across the nation.
