What is the correct disposal practice for chemotherapy waste?

• A. Place cytotoxic waste in regular trash after double-bagging.
• B. Rinse waste with water and pour down drain.
• C. Store waste in a sealed box indefinitely.
• D. Use approved cytotoxic waste containers; follow USP <800> hazardous waste handling; label and dispose per institutional policy and local regulations.

Answer: (D)

Safe disposal of chemotherapy waste requires proper containment and regulatory compliance to minimize exposure and environmental impact. The best practice is to use approved cytotoxic waste containers that are leak-proof, closable, and resistant to puncture, so any residual drug or contaminated material is securely contained. Label these containers clearly with cytotoxic hazard information and the date, and dispose of them according to institutional policy and local regulations, with the waste handled through the approved hazardous waste stream.

This approach aligns with USP <800> hazardous waste handling, which sets the standards for how cytotoxic waste should be managed, labeled, and transported within a facility and off-site for proper treatment. It also ensures staff safety by preventing exposure from spills or leaks and helps the environment by keeping hazardous residues out of regular trash and drains.

In contrast, disposing of cytotoxic waste in regular trash, rinsing materials and pouring the contents down a drain, or storing sealed waste indefinitely all fail to meet safety and regulatory requirements. They risk exposure to workers and the community and ignore the mandated pathways for hazardous waste management.
