What Not to Store in a Flammable Cabinet

One well established safety procedure is to store flammable materials in a proper flammable cabinet. Training sessions, Chemical Hygiene Plans, SOPs, etc. all cover the fact that flammables must be stored appropriately. But have you considered what should not be stored in a flammable cabinet?

Proper chemical segregation is a key laboratory safety element that significantly decreases the potential for incidents, accidents, and near misses. Acids and bases need to be stored in their own dedicated storage cabinets, separate from flammable storage. Oxidizers must be stored separately from flammables. And any potential source of ignition should never be stored inside a flammable storage cabinet. Potential ignition sources can include a various materials, and should be explored for your site specific inventory. No more than 60 gallons of Category 1, 2, or 3 flammable liquids, and no more than 120 gallons of Category 4 flammable liquids can be stored in an individual cabinet.

While developing procedures and training, remember to include what should not be stored in flammable cabinets as well as the proper storage of flammable materials.
