GHS hazard and precautionary statement lookup

A hazard statement describes the nature of a hazard, and where relevant its degree, for a given hazard class and category. Each one has a code such as H315. Under the GHS the code is for reference only. It is not part of the statement text and should not replace it on a label.

A precautionary statement describes measures to reduce or prevent harm from exposure to a hazardous chemical or from improper storage or handling. Codes are grouped by type: P1xx general, P2xx prevention, P3xx response, P4xx storage and P5xx disposal. Combined statements such as P305+P351+P338 join several statements into one.

EUH statements are EU-specific phrases in Annex III of the CLP Regulation. They cover supplemental hazard information, supplemental label elements for certain mixtures, and the hazard classes the EU added in 2023, such as endocrine disruption and PBT/vPvB. They are not part of the UN GHS.

Each regulation adopts GHS revisions on its own timetable and can adjust wording. UN GHS Rev.11 is the latest edition. OSHA's 2024 update is based primarily on Rev.7 with some Rev.8 elements, Canada's Hazardous Products Regulations on Rev.7 (Rev.8 for chemicals under pressure) and Mexico's NOM-018-STPS-2015 on the 5th revised edition. For example, UN GHS Rev.8 deleted P310 to P315 and added P316 to P319, but EU CLP still lists P310 to P315. OSHA's Appendix C does not use codes at all. The text that applies to your label or SDS is the text in the regulation for the market you sell into.

The links come from the UN GHS Rev.11 Annex 3, section 3 label matrix only. A P statement is linked when the matrix lists it for at least one category that uses the H statement, so check the category and the conditions for use. EU CLP, US OSHA, Canada (GHS Rev.7) and Mexico assign their own P statements, so the links are shown only in the All and UN views. Check the regulation for your market.

Canada's Hazardous Products Regulations use the GHS statements but do not require the codes on labels, and labels and SDSs must be in English and French. Canada also has its own classes with no GHS code, such as combustible dusts and simple asphyxiants; OSHA has the same combustible dust and simple asphyxiant statements (29 CFR 1910.1200 App. C, C.4.31). Mexico's NOM-018-STPS-2015 lists H and P codes with official Spanish text, based on the GHS 5th revised edition. It does not include environmental hazard statements.
