Which regulation ensures employees know about hazardous waste risks?

The regulation that ensures employees are informed about hazardous waste risks is primarily tied to the Occupational Safety and Health Administration (OSHA), which has set forth guidelines under the Hazard Communication Standard (HCS). This standard mandates that employers communicate information about hazardous chemicals to their employees through labels, safety data sheets (SDS), and training programs.

While the other options, such as the EPA, play a crucial role in the regulation and management of hazardous waste and environmental protection, they primarily focus on the broader spectrum of waste disposal regulations and environmental safety rather than directly addressing employee training and communication about those hazards. The FDA is concerned with food and drug safety regulations, and CHCS does not pertain to the communication of hazardous waste risks specifically.

Understanding the context of these regulations highlights that OSHA's role is crucial in ensuring workplace safety and health by directly addressing hazards employees may encounter, including those related to hazardous waste.
