Which federal agency is responsible for setting and enforcing standards for workplace safety in the U.S.?

The Occupational Safety and Health Administration (OSHA) is the federal agency tasked with setting and enforcing standards for workplace safety in the United States. Established under the Occupational Safety and Health Act of 1970, OSHA's primary role is to ensure safe and healthful working conditions by creating and enforcing regulations that employers must follow to protect their employees from potential hazards.

OSHA develops occupational safety standards that address a wide range of workplace issues, including exposure to toxic chemicals, fall protection, and the use of personal protective equipment. The agency conducts inspections and can enforce compliance through penalties or citations when workplace safety standards are not met. This fostering of safe work environments helps reduce the risk of work-related injuries and illnesses, making it a crucial entity in the realm of workplace safety.

In contrast, other agencies like the CDC (Centers for Disease Control and Prevention) focus on public health and disease control; the FDA (Food and Drug Administration) oversees food and drug safety; and the HRSA (Health Resources and Services Administration) is focused on improving access to healthcare for underserved populations. While all these organizations play vital roles in public health and welfare, OSHA is specifically designed to enforce workplace safety regulations, making it the correct answer in this context.
