What is flammable material storage?

Flammable material storage is chemical / hazmat storage for substances that ignite easily. It is related to — but not identical with — DOT Class 3 flammable liquids or Class 2.1 flammable gases: a toxic Class 6.1 chemical can still require flammable storage when fire risk is present.

Why this flag matters for buildings

The flammable storage flag answers a building question: do you need a fire-rated enclosure and flammable-liquid/gas controls? Use it with the chemical storage guide and the hazard class & division index.
