H226 — Flammable liquid and vapor
The GHS hazard statement for flammable liquids, category 3. Here is what it means, the label elements that travel with it, and the substances that carry it.
What it means
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:
Reference information, not legal or professional advice. Statement texts and allocations follow GHS Rev 9 / 29 CFR 1910.1200 Appendix C as implemented by our classification engine; the regulatory text and agency practice control. Claims last reviewed July 23, 2026.
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.
