Flammable Liquid (Class 3) Storage

Flammable liquids (DOT Class 3 / GHS flammable-liquid categories) are the largest storage group in this database. Category numbers describe relative flash-point severity.

Class, Division, and GHS meaning

Class 3 is flammable liquids under DOT. “Division 3” on a multi-hazard label usually points back to that Class 3 flammable-liquid risk. GHS Categories 1–4 refine flash point / boiling point banding used for container sizes, cabinet ratings, and building selection.

Storage implications for rental buildings

Match flash point and volume to fire-rated storage, grounding/bonding practices, and segregation from oxidizers. US Hazmat Rentals flammable-storage buildings are commonly specified for Category 1–3 inventories and mixed drum/tote workflows.
