Which item is used to classify waste streams in hazardous drug management?

• A. SOP
• B. SDS
• C. U-list
• D. RCRA

Answer: (C)

Classification of hazardous waste streams in hazardous drug management relies on regulatory lists that identify what wastes are considered hazardous. In U.S. practice, wastes are categorized under F-, K-, P-, and U-lists as part of the RCRA framework. The U-list specifies discarded commercial chemical products that become hazardous waste when they are discarded, so it is the list used to identify and classify waste streams that originate from such chemicals, guiding proper disposal. Safety Data Sheets describe hazards of a chemical but do not by themselves classify waste streams, and standard operating procedures cover handling steps rather than waste classification. The regulatory framework sets the rules, but the actual waste-stream classification relevant to many pharmaceutical wastes is done using the U-list.
