Proper handling and storing of flammable liquids is important to worker health and safety. The typical workplace stores flammable liquids in two ways:

• Reserve storage in drums.
• Operational storage in small quantities for use at work stations.

For safe storage, drums should have emergency venting devices installed in the top to prevent any internal pressure build-up if the drum is exposed to heat. Proper vents also incorporate emergency relief devices, which blow out under extreme pressure.

Drums should be connected to a grounding system; this eliminates static electrical build-up when dispensing from the drum. If your plant does not have a drum storage room, drums should be stored in a safety cabinet; they are available in sizes to hold drums vertically or horizontally.

Transfer of liquids relies on dispensing methods. This can be done in one of two ways:

• Gravity flow for horizontally stored drums.
• Pump method for vertically stored drums.

OSHA has developed very detailed regulations covering the storage of flammable and combustible liquids. Storage categories include:

• Containers and portable tank storage §1910.106(d).
• Storage cabinets §1910.106(d)(3).
• Inside storage rooms §1910.106(d)(4).
• Storage inside buildings §1910.106(d)(5).
