Prevention · precautionary statement
P212 — Avoid heating under confinement or reduction of the desensitising agent.
Prevention statements describe how to keep the harm from happening at all. No substance with a harmonised EU classification carries this code.

What P212 says
Avoid heating under confinement or reduction of the desensitising agent.
Prevention · GHS revision 9
Does your label need P212? That depends on the hazard classes of your product, on whether it goes to the public or to professionals, and on what else is already on the label — Annex IV column 5 lets one statement remove another. Work it out from a classification →

P212 in the 24 official EU languages
A label put on the market in an EU country must carry the wording of that country's own language version of CLP — not a translation of the English one. These 24 lines are quoted from the consolidated regulation, Annex IV, and are the text to print.

Source: CELEX:02008R1272-20260501, Annex IV. © European Union, https://eur-lex.europa.eu — only the electronic Official Journal of the European Union is authentic. Irish is one of the 24 official languages and its H and P texts are printed inside the multilingual Annex tables, but no consolidated CLP has ever been published in Irish — which is why an Irish-primary label cannot be built here.
03 · Legal status
Where P212 is current
GHS is a United Nations model text, revised every two years, and each jurisdiction adopts a revision on its own timetable. A code can be legally current in one system and deleted in another — that is normal, not an error.
| Jurisdiction | Basis | Status of P212 |
|---|---|---|
| EU CLP | Regulation (EC) 1272/2008 CLP Annex IV, Part 2 (consolidated) | Current |
| US OSHA HazCom | 29 CFR 1910.1200 Appendix C UN GHS Rev.7 (final rule of 20 May 2024) | Current |
| US HazCom 2012 | legacy · GHS Rev.3 UN GHS Rev.3, Annex 3 | not in this system |
| UN GHS | Rev.11 (2025) UN GHS Rev.11, Annex 3 | Current |

Substances carrying P212
No substance with a harmonised classification in CLP Annex VI carries this code. That does not mean it is unused — suppliers apply it to their own mixtures.
