6. Empty Chemical Containers
- Ensure the item held in the container is NOT on the EPA P-List
- If the material that was once in the container is on the P-List, the container itself is a hazardous waste and must be treated as such
- If the container held a liquid, ensure the inside of the container is dry
- If the container held a solid, make sure almost all of the material has been removed
- EPA requires less than 3% by weight or 1 inch of residue (whichever is less) for any contained chemical, we want to be well under that limit
- DOT requires that the container does not pose a hazard
- ALL markings that denote what the container once held must be defaced (DOT regulations use the terms: removed, obliterated, or securely covered)
- Label the container as “EMPTY”
- Dispose of the container uncapped
- Do NOT dispose of any container in such a way that it could possibly expose other individuals or the environment to whatever was in the container
- Plastic, metal and fiberboard containers only can be placed in trash cans.
- Empty glass containers must be placed in a rigid box that is marked as "broken glass“. These boxes may be placed with (not in) the regular trash for collection by custodial staff. Be sure to tape the box securely shut.
- For aerosol cans, the container must be completely empty and at atmospheric pressure (easily crushable by hand)
- If disposing of 5 gallon solvent containers, they must be disposed of in a DUMPSTER, not the BSB trash compactor
