Read about UCSD's storage requirements for flammable and combustible liquids.
California fire codes strictly limit the total quantity of flammable and combustible liquids and container size that may be stored in a facility.
The hazard classification of a liquid determines the type and size of container it may be stored in. See Flammable and Combustible Liquids Overview to determine hazard class.
Chart 1 describes the maximum type and size of container you're allowed to store based on the liquid's hazard classification.
