Wooden Safety Flammable Storage Cabinets meet the OSHA, NFPA and UFC standards for construction with a self-closing door.
Metal flammable doors, while certainly able to protect against an open flame, can distort and change shape in a fire, eventually exhuming the internal contents and putting them at risk of making contact with fire. Wood, in contrast, must burn all the way through. With a heavy-duty plywood exterior, the amount of time it takes to burn through the exterior is equal to that of a metal flammable door.
What makes a wooden flammable cabinet the better choice, then? Wood is a thermal insulator, so any fire on the cabinet surface will have little to no effect on the contents inside. Conversely, metal is a conductor of heat and a combination of distortion and rising internal temperature puts the contents at risk.
