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.
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.
