Liquids whose vapor ignites readily. Categories run from 1 (most flammable) down to 4, set by flash point — the lowest temperature at which the liquid gives off ignitable vapor — together with initial boiling point.
Precautionary statements paired with H226
When the engine writes SDS Section 2 or a container label for a product carrying H226, these are the P-codes it assigns, in the official Annex 3 groups:
| Prevention | P210 | Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. |
| P233 | Keep container tightly closed. | |

Substances that carry H226
149 of the 4,225 substances in our database carry H226 when classified in pure form — recognizable examples:
- acetic acid — CAS 64-19-7

- styrene — CAS 100-42-5
- n-butyl acetate — CAS 123-86-4
The engine writes these for you.
When SDS HQ authors an SDS or a container label, it assigns the hazard statements, signal word, pictograms, and precautionary statements from these same tables — automatically, with the calculation shown.
