H330 — Fatal if inhaled
The GHS hazard statement for acute toxicity, inhalation, categories 1 and 2. Here is what it means, the label elements that travel with it, and the substances that carry it.
What it means
Serious harm from breathing the substance — as gas, vapor, dust, or mist — over a single short exposure. Categories are set from acute toxicity estimates (ATE) per GHS Chapter 3.1.
Precautionary statements paired with H330
When the engine writes SDS Section 2 or a container label for a product carrying H330, 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.
