H336 — May cause drowsiness or dizziness
The GHS hazard statement for specific target organ toxicity, single exposure, category 3 (narcotic effects). Here is what it means, the label elements that travel with it, and the substances that carry it.
What it means
Effects on a specific organ or body system from a single exposure. Categories 1 and 2 cover significant organ damage (proven or presumed vs. suspected); Category 3 covers transient effects — airway irritation or drowsiness/dizziness — that pass after exposure ends.
Precautionary statements paired with H336
When the engine writes SDS Section 2 or a container label for a product carrying H336, 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.
