Final answer:
Hazardous waste in the workplace must be identified by workplace labels to ensure proper handling and safety.
Step-by-step explanation:
If an employer produces, stores, handles, or disposes of hazardous waste at a workplace, the waste must be identified by workplace labels. This ensures that all individuals in the workplace are aware of the materials they are dealing with, helping to prevent accidents and ensure proper handling. Under the Resource Conservation and Recovery Act (RCRA), generators of hazardous waste are responsible for determining whether their waste is hazardous and making sure that it is properly managed throughout its entire lifecycle. According to the Occupational Safety and Health Administration (OSHA), employers must inform workers about chemical hazards through training, labels, alarms, color-coded systems, chemical information sheets, and more, emphasizing the significance of proper labeling.
