H302 — Harmful if swallowed
The GHS hazard statement for acute toxicity, oral, category 4. Here is what it means, the label elements that travel with it, and the substances that carry it.
What it means
Serious harm — up to and including death — from swallowing a single dose or several doses within 24 hours. Categories 1 (most severe) onward are set from acute toxicity estimates (ATE) per GHS Chapter 3.1.
Precautionary statements paired with H302
When the engine writes SDS Section 2 for a product carrying H302, these are the precautionary statements it assigns, with combined statements written as one line:
Reference information, not legal or professional advice. Statement texts and allocations follow 29 CFR 1910.1200 Appendix C (the GHS as adopted by OSHA HazCom 2024) 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, it assigns the hazard statements, signal word, pictograms, and precautionary statements from these same tables — automatically, with the calculation shown.
