Chemotherapy & Hazardous Drugs
Drugs are classified as hazardous if they may cause cancer, developmental or reproductive toxicity or harm to organs at low doses. They include drugs used for cancer chemotherapy (also called antineoplastics), antiviral drugs, hormones, some bioengineered drugs and other various drugs. To determine if a drug is classified as hazardous check the NIOSH List of Antineoplastic and Other Hazardous Drugs in Healthcare Settings (2014).
Safe Use and Handling
Follow safety precautions when working with hazardous drugs. These include use of exhausted enclosures, procedures to avoid personal exposure and contaminating surfaces, personal protective equipment (PPE) and training of personnel in hazard awareness and safe work practices.
Federal and state regulations and guidelines exist for the use, handling, storage, treatment and disposal of hazardous drugs in clinical and research settings. EH&S has developed guidance that includes procedures for safety, compliance and best practices. For research involving hazardous drugs at UW, follow these guidelines:
For veterinary clinical care, use the Veterinary Hazardous Drug Program Guide from Washington State Labor & Industries.
Waste: Trace vs Non-Trace
Manage chemotherapy (chemo) and hazardous drug waste separately from other waste streams such as biohazardous waste. Chemo/hazardous drug waste should not be autoclaved. Collect chemo/hazardous drug waste as either trace or non-trace waste as defined below.
"Trace" refers to empty containers or containers that have less than 3% of the original quantity of drug remaining, such as sharps, empty syringes and vials. An "empty" container is one in which all contents have been removed by normal means such as aspiration, pouring or flushing.
Non-Trace Waste and P-Listed Drugs
Non-trace chemo/hazardous drug waste refers to unused or expired drugs, containers with more than trace amounts of chemo/hazardous drug, contaminated PPE and contaminated items from preparation, use, and clean-up. Dispose of non-contaminated PPE and other items in the trash.
Environmental Protection Agency (EPA) P-listed drugs are acutely hazardous drugs regulated by federal law. Handle all P-listed drug waste (including empty containers and trace amounts) as non-trace chemo/hazardous drug waste. P-listed chemo/hazardous drugs include:
||Constituent of Concern
||Product Name Examples
||Warfarin and salts (>0.3%)
||Adrenaline, EpiPen, Eppy/N, Epifrin, Epinal, Anaphylaxis kit, Epinephrine, Racepinephrine, Racord, Primatene inhaler
||Nicotine and salts
||Nicotine patches, Habitrol, Nicoderm, Nicorette, Nicotrol, Tetrahydronicotyrine
