Environment, Health and Safety (EH&S) is in the process of tagging all chemicals in all buildings on campus in response to new chemical inventory requirements issued by the UC Office of the President (also see MAQ project page).
Town Halls: Introduction to chemical tagging
EH&S is hotsting virtual town halls throughout the...
Maximum Allowable Quantities are maximum limits of storage and use of hazardous chemicals as established by the California Fire Code to ensure fire and life safety of occupants and first responders. MAQs will depend on the quantities, types and physical state of hazardous materials. It will also depend on building characteristics.
In the coming years, the university will conduct an analysis of MAQ levels in all buildings across campus, which will depend on complete and accurate chemical inventories.
Before tagging begins, take an hour or two to sort through your chemicals and separate unwanted waste. Centralize waste in a secure location with secondary containment. Our hazardous waste team will pick up the waste separately either the day of tagging or up to 3 business days after.
EH&S has a standard process of conducting a walkthrough of spaces in the week(s) before tagging begins. More information will be provided during the walkthroughs and within the email correspondence to set up those meetings.
Tags will have difficulty adhering to containers with condensation. Dry the container before affixing the tag. If there are other factors preventing tag adhesion, reach out to EH&S at cheminv@@berkeley.edu for advice.
