Which organization is responsible for dictating requirements concerning work-related safety?

The Occupational Safety and Health Administration (OSHA) is the organization responsible for promoting and ensuring workplace safety and health. Established under the Occupational Safety and Health Act of 1970, OSHA sets and enforces standards aimed at preventing workplace injuries, illnesses, and fatalities. It provides guidelines and regulations that employers must follow to ensure the safety and health of their employees in various industries, including construction, manufacturing, and more.

In context, the other organizations listed have distinct areas of focus. The Centers for Disease Control and Prevention (CDC) primarily deals with public health issues and disease prevention rather than workplace safety protocols. The Federal Aviation Administration (FAA) is involved with aviation safety and regulations related to air travel and aircraft operations. The Environmental Protection Agency (EPA) is tasked with protecting the environment and public health in relation to environmental policies, rather than directly addressing workplace safety.

Thus, OSHA's specific mandate to regulate and enforce safety standards within workplaces clearly identifies it as the correct choice in this context.
