Proper storage prevents vapor buildup and limits fuel for potential fires. NFPA 30 Overview
| Class | Flash Point (FP) | Boiling Point (BP) | Example | |-------|----------------|-------------------|---------| | | <73°F (22.8°C) | <100°F (37.8°C) | Ethyl ether | | IB | <73°F | ≥100°F | Acetone, gasoline | | IC | 73–100°F | – | Turpentine | | II | 100–140°F | – | Diesel fuel (some grades) | | IIIA | 140–200°F | – | Home heating oil | | IIIB | ≥200°F | – | Cooking oils, lubricating oils | nfpa 30 ppt
The code's primary goal is to provide fundamental safeguards by managing how liquids are contained and identifying potential ignition sources. Modern editions have shifted terminology to focus on "ignitable liquids," though traditional "flammable" and "combustible" labels are still widely used based on flash points and boiling points.
