Which law requires employees to be informed about hazardous substances?

The Hazard Communication Standard (HCS) is the law designed specifically to ensure that employees are informed about hazardous substances they may encounter in the workplace. Enforced by the Occupational Safety and Health Administration (OSHA), this standard requires employers to provide information about the chemicals, their hazards, and appropriate safety measures through labeling, safety data sheets (SDS), and employee training.

The focus of the HCS is on the right to know about hazards associated with chemicals used in work environments, which is particularly relevant in settings like salons and spas where various products are used. By mandating clear communication regarding hazardous substances, the HCS helps promote a safer workplace and reduces the risk of exposure to harmful chemicals.

While the Occupational Safety and Health Act provides a broader framework for workplace safety and health, it is the Hazard Communication Standard that specifically addresses the requirement for employees to be educated on hazardous materials, making it the correct choice. The Clean Air Act and the Safe Drinking Water Act address environmental and water safety concerns, respectively, but they are not focused on informing employees about workplace chemical hazards.
