Are used laboratory glassware that contacted BDW considered BDW?

• A. Yes, if contaminated with infectious material.
• B. No; never BDW.
• C. Always BDW regardless of contamination.
• D. Only if the glassware is damaged.

Answer: (A)

The main idea is that the category of Biomedical Waste includes waste that has been contaminated with infectious materials. For used laboratory glassware, the key factor is whether it has actually become contaminated with infectious material. If it has, then it qualifies as BDW and should be managed accordingly (e.g., placed in BDW containers or decontaminated before disposal). If the glassware did not become contaminated with infectious material, it is not BDW. Damaged glassware or mere contact without contamination does not automatically make it BDW. In short, contamination with infectious material is the deciding factor.
