Which of the following is NOT considered hazardous waste?

The answer is correct because non-cytostatic medicines are not classified as hazardous waste. Hazardous waste typically includes materials that can be harmful to human health or the environment, which includes infectious waste (materials that could potentially contain pathogens), radioactive waste (which comes from radioactive materials), and offensive waste (which may not pose an infection risk but is still deemed inappropriate to handle in regular waste streams). Non-cytostatic medicines, however, do not fall under these categories as they do not pose the same level of threat as those that are cytotoxic or involve pathogenic microbes or radiation. Understanding the classification of waste is crucial in dental practice to ensure safety and compliance with health regulations.
