Trace Waste includes which of the following items?

• A. Full chemical waste
• B. Hazardous wastes
• C. Nonhazardous waste
• D. Empty containers, needles, syringes, gowns, pads, empty IV sets

Answer: (D)

Trace waste covers disposable items that may still have tiny amounts of hazardous drug residues after handling. These items are not truly empty in a contamination sense, so they aren’t trash as regular nonhazardous waste. The items listed—empty containers, needles, syringes, gowns, pads, and empty IV sets—are classic examples because they can carry trace amounts of hazardous drugs even after use. Proper disposal as trace/regulated waste helps protect staff and the environment from exposure.

Full chemical waste and nonhazardous waste aren’t appropriate labels here: full chemical waste implies bulk chemical products, and nonhazardous waste would be regular trash without any contamination. Simply labeling something as hazardous waste is too broad and misses the nuance that the waste is only contaminated at trace levels.
