Waste should be separated by hazard class and clearly labeled to ensure safe handling and proper disposal. Different streams—chemical, biological, sharps, and others—need their own containers with contents and hazard information displayed, so the waste can be treated correctly and workers remain protected. Color coding alone isn’t enough, since the same color can hide different hazards and different hazards can use the same color; volume or random sorting don’t address the safety risks involved. Proper labeling typically includes what the waste is, any hazards, and the date or source, guiding safe transport and disposal steps.
