P307 — IF exposed:

A response statement from GHS Annex 3 — the precautionary half of the label language on SDSs and containers.

Response (P3xx)
ANNEX 3 ROLE
First aid, fire, spills — when it happens anyway
ASSIGNED BY THE ENGINE
Not automatically — appears where suppliers or other GHS classes require it

The trailing colon is not a typo: P307 is a condition stem. On sheets and labels it prints combined with the response steps that follow it — for example "P303+P361+P353" reads as one instruction.

Withdrawn in later GHS revisions. OSHA HazCom 2024 uses P308 ("If exposed or concerned:") for target organ toxicity; older sheets still carry P307.

Which hazards call for P307

None of the hazard statements in our catalog calls for P307; it appears on labels where suppliers or other GHS classes require it.

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.
