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

The Occupational Safety and Health Administration (OSHA) is the correct answer because it is the federal agency established under the Occupational Safety and Health Act of 1970, with the primary mission of ensuring safe and healthy working conditions for employees. OSHA sets and enforces standards for workplace health and safety, providing training, outreach, education, and assistance to help employers and employees understand and comply with these standards.

OSHA's authority allows it to conduct workplace inspections, investigate complaints, and enforce regulations that protect workers from hazards such as toxic substances, machinery risks, fall hazards, and other safety concerns. Through its efforts, OSHA plays a critical role in preventing workplace injuries and illnesses, making it the designated agency responsible for enforcing health and safety regulations in the workplace.
