Can materials be stored on top of flammable storage cabinets?

OSHA expects that all flammable liquids as defined in 1910.106(a)(19) be kept in a flammable storage cabinet, inside storage room, or flammable storage warehouse per 1910.106(d).

However, there is an exemption under 1910.106(e)(2)(i) for incidental storage which allows employers to store up to 25 gallons of Category 1 and 120 gallons of Categories 2, 3, and 4 in containers in any one “fire area” of the facility outside a flammable storage cabinet or storage room. However, it is always a best practice to do so.

Also, local or state fire code may dictate storage requirements; therefore, contact local fire authorities as they generally know what OSHA requires as well as local and state fire code and will be the best source of information regarding storage.

Also, an employer’s liability insurance carrier may require or restrict the storage of flammable materials, which may affect insurance rates.

Other types of materials stored around and/or on top of the cabinets must adhere to general housekeeping requirements under 1910.22(a), and 1910.106(e)(9) which will tend to control leakage and prevent the accidental escape of flammable liquids. All spills must be cleaned up promptly.
