Which organization typically oversees the enforcement of workplace safety regulations?

The Occupational Safety and Health Administration (OSHA) is the primary agency responsible for overseeing and enforcing workplace safety regulations. Established under the Occupational Safety and Health Act of 1970, OSHA's mission is to ensure safe and healthful working conditions for employees by setting and enforcing standards and providing training, outreach, education, and assistance.

OSHA conducts inspections and investigations to ensure compliance with safety standards, as well as to address and rectify unsafe working conditions. This makes it specifically equipped to handle workplace safety issues, making it the correct answer to this question. Other organizations listed have different mandates; for instance, the Department of Labor encompasses a broader range of labor issues beyond just safety, while the Employee Rights Agency and the Federal Trade Commission focus on labor rights and trade issues, respectively.
