Chemical waste is regulated by the Environmental Protection Agency (EPA) through the Resource Conservation and Recovery Act (RCRA). It cannot be disposed of in regular trash or in the sewer system. Most chemical wastes must be disposed of through the EHS Hazardous Waste Program. To have hazardous waste removed from your laboratory, do the following:
- Store chemical wastes in appropriate containers; plastic bottles are preferred over glass for storing hazardous waste when compatibility is not an issue. Segregate chemical waste by compatibility, and not alphabetically.
-
Chemical waste containers must be labeled with the following information:
- Full chemical name and quantity of the waste. For mixtures, each chemical must be listed. Abbreviations, acronyms and ditto marks ("") to replace words are not allowed, as this does not comply with The Hazard Communication Standard;
- Date of waste generation;
- Place of origin (department, room number);
- PI's name and telephone number;
- Bottle number assigned on corresponding waste sheet; and
- The tag or label must have the words: "Hazardous Waste."
