Hazardous Materials

One of the most important safety devices in a laboratory is a properly functioning fume hood. The fume hood protects users by containing and exhausting airborne hazards; it does this by constantly pulling room air into the hood and exhausting it from the roof. Fume hood sashes also provide shielding in the event of an explosion or fire inside the hood.

EH&S sends hazardous chemical waste generated by the campus to several facilities that treat or dispose of chemicals. EH&S derives the recharge rates for hazardous chemical waste from the rates charged by the waste disposal/treatment facilities plus the costs for transportation, contractor labor, packaging materials, and other supplies. In addition, a nominal per-item charge is included in the recharge rate to encourage consolidation of compatible wastes.

If you have any questions about recharge rates, please contact the Recharge Administrator at...

California Fire Code (CFC) regulations limit the quantity of flammable and combustible liquids that can be stored in research and teaching laboratories. This fact sheet provides a simplification of the complicated CFC regulations, and establishes standard practice at University of California, Berkeley (UC Berkeley). For questions not covered in this fact sheet, or for assistance with more complicated issues, please contact the Office of Environment, Health & Safety (EH&S) for situation-specific guidance.
