Nfpa Code 30 Jun 2026

These are the most hazardous. Class I liquids have flash points below 100°F (37.8°C). They are subdivided further:

Over the last century, NFPA 30 has evolved from a simple list of "do's and don'ts" into a sophisticated engineering document. Today’s code incorporates complex physics regarding vapor pressure, flash points, and explosion venting, adapting to modern chemical inventories that were inconceivable in 1913.

NFPA 30 mandates rigorous standards for storage infrastructure to prevent catastrophic leaks or fires. Key requirements for aboveground storage tanks include:

Key cabinet requirements under NFPA 30:

If you are using a previous edition (e.g., 2018 or 2021), check with your local Authority Having Jurisdiction (AHJ) to see which edition they enforce.

Despite decades of publication, inspectors routinely find the same NFPA 30 violations:

This is a crucial section for facility managers and safety professionals. NFPA 30 is by itself, but it becomes mandatory when adopted by: nfpa code 30

NFPA 30 divides flammable and combustible liquids into five classes (I, II, IIIA, IIIB). Each class triggers specific storage and handling rules.

In the world of industrial safety, few regulations carry as much weight as . Officially titled the Flammable and Combustible Liquids Code , this document is the gold standard for the storage, handling, and use of dangerous liquids in the United States and beyond.

| Class | Flash Point | Boiling Point | Examples | |-------|-------------|---------------|-----------| | | Below 73°F (22.8°C) | Below 100°F (37.8°C) | Ethyl ether, acetaldehyde | | IB | Below 73°F (22.8°C) | At or above 100°F | Acetone, gasoline, ethanol | | IC | 73°F to 100°F (22.8–37.8°C) | Any | Turpentine, some paints | | II | 100°F to 140°F (37.8–60°C) | Any | Diesel fuel (some grades), kerosene | | IIIA | 140°F to 200°F (60–93°C) | Any | Fuel oil No. 2, some hydraulic fluids | | IIIB | At or above 200°F (93°C) | Any | Cooking oils, ethylene glycol |
