HAZARDOUS MATERIALS INVENTORY
UNIVERSITY OF CALIFORNIA
AGRICULTURE AND NATURAL RESOURCES
INJURY AND ILLNESS PREVENTION PROGRAM
Each University of California Research and Extension Center (REC) that stores chemicals for
use in general operations and research or education projects must maintain an accurate, up-todate inventory of chemicals in the work place. This is to comply with federal and state
regulations that require submission of an annual inventory of hazardous chemicals under
Community Right-to-Know and emergency response Business Plan laws. It is also part of an
employee Hazard Communication program.
Section 25501.1 of the California Health and Safety Code requires businesses to provide
information on all hazardous substances listed by the U.S. Environmental Protection Agency at
Title 49, Parts 172 and 173 of the Code of Federal Regulations. This chemical roster essentially
duplicates the class of materials for which a Material Safety Data Sheet (MSDS) must be
produced. Thus, any chemical for which an MSDS has been produced may be reportable.
RECs may have varying definitions of minimum quantities that must be reported, but in general,
materials must be reported if quantities equal to or greater than 55 gallons, 500 pounds, or 200
cubic feet of hazardous materials are handled, used or stored. Any quantity of acutely
hazardous materials must be reported. For your information, a list of acutely hazardous
materials is posted on the UC Davis Environmental Health and Safety (EH&S) website at
http://www-ehs.ucdavis.edu/cis/cinvahm.cfm. Additionally, state law requires that businesses
list materials classified as hazardous wastes on the annual inventory.
Failure to maintain and submit an updated inventory could expose RECs to regulatory
citations.
If the REC does not have a specific form, or if the REC does not have quantities that require a
report, the attached inventory form should be completed and maintained for each REC.
The chemical inventory along with appropriate MSDS must be kept in a readily available area
for employee review and must be maintained in an organized manner. Employee training
should be documented and placed in the Injury Illness Prevention Plan (IIPP) binder. Each
container of a hazardous substance must be labeled. Labels must identify the hazardous
chemical present, appropriate hazard warnings and the name and address of the manufacturer,
importer or other responsible party. If chemicals are used infrequently, it may be helpful to
record the date of usage on the label. If a chemical is transferred into another container, the
container must be labeled with the name of the chemical and an appropriate hazard warning.
Containers should be properly sealed. If a container has a leak, a hazardous waste condition
exists. Contact ANR EH&S (530-752-6024) to arrange for disposal of the waste. For additional
information about proper management of hazardous waste, consult the ANR EH&S Policy and
Procedures for Storage and Removal of Regulated Waste:

If a pesticide is removed from registered list by regulatory action, it should be disposed of
immediately. Similarly, any residual amounts of experimental pesticides should be disposed
promptly when the experiment is completed. First, you should contact the manufacturer to see if
they will accept it back. If you are unsuccessful in contacting the manufacturer and arranging
for the company to accept the returned chemical, work with ANR EH&S to arrange for proper
disposal.
The Hazard Communication Program is a part of the REC’s IIPP.
