Final answer:
When classifying a HAZMAT with multiple hazard classes, it is important to consider listed hazardous wastes, characteristic hazardous wastes, and mixed wastes that contain radioactive material. The EPA regulates mixed wastes under the RCRA and Atomic Energy Act to ensure proper handling and management.
Step-by-step explanation:
When classifying a HAZMAT with more than one hazard class based on shipping names and radioactive material types, it is important to consider the different types of hazardous wastes. Listed hazardous wastes are materials specifically listed as hazardous wastes and can come from non-specific sources, specific sources, or discarded chemical products. Characteristic hazardous wastes exhibit properties such as ignitability, corrosivity, reactivity, or toxicity. Mixed wastes are hazardous wastes that also contain radioactive material and are regulated under the Resource Conservation and Recovery Act (RCRA) and Atomic Energy Act. The Environmental Protection Agency (EPA) has developed a hazardous waste management program to ensure proper handling of these wastes.
