Flammable liquids are classified by flashpoint (Class IA-IC below 100°F; Class II 100-140°F; Class III above 140°F). Requirements cover storage tank design and venting, inside storage room construction (2-hour fire resistance, explosion-proof electrical, self-closing doors, mechanical ventilation), bonding and grounding for dispensing, and quantity limits for unprotected storage.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
