Section 6: Flammable Liquids

Storage Containers

Flammable and combustible liquids should be stored in only certain types of approved containers. Containers used by the manufacturers of flammable and combustible liquids generally meet these specifications.

Safety Can

The type of container needed depends on the quantity and class of flammable or combustible liquid. A safety can is an approved container of not more than 5 gallons capacity that has a spring closing lid and spout cover. Safety cans are designed to safely relieve internal pressure when exposed to fire conditions.

A flammable liquid storage cabinet is an approved cabinet that has been designed and constructed to protect the contents from external fires.

Storage Considerations

  • Quantities should be limited to the amount necessary for the work in progress
  • No more than 10 gallons of flammable and combustible liquids, combined, may be stored outside of a flammable storage cabinet unless safety cans are used.
  • Storage of flammable liquids must not obstruct any exit.
  • Flammable liquids should be stored separately from strong oxidizers, shielded from direct sunlight, and away from heat sources.
  • Containers must be sealed when not in use.

Handling Precautions

Control all ignition sources in areas where flammable liquids are used. Smoking, open flames and spark producing equipment should not be used.

Flammable Aerosols

Flammable aerosols are in pressurized containers that may rupture when exposed to fire. As with flammable liquids, these should be stored in a flammable storage cabinet.
