Which hazards call for P103

None of the hazard statements in our catalog calls for P103; it appears on labels where suppliers or other GHS classes require it.

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.
