penggolongan sampah
1. Hazardous chemical waste is categorized into the following hazard classes:
3. Dry material (paper, rag, towels, gloves, Kim-Wipes, etc.) That is contaminated with flammable or extremely toxic chemicals must be treated as hazardous chemical waste.
4. Sharps (needles, razor blades, etc.) must be encapsulated (Place the sharps in a "puncture resistant" container or a plastic/metal container, and then fill it with paraffin or plaster of Paris.). Discard the containers of encapsulated sharps as non-hazardous trash.(http://www.chem.tamu.edu/safety/hazardous_waste.html#Classification)
