P334 — Immerse in cool water or wrap in wet bandages.
Response statements describe what to do once exposure, a spill or a fire has happened. No substance with a harmonised EU classification carries this code.
01 · Wording
What P334 says
Immerse in cool water [or wrap in wet bandages]. The wording is incomplete on purpose. The square brackets mark an alternative: immerse in water, or wrap in wet bandages.
Immerse in cool water or wrap in wet bandages. How it usually reads on a label. We show it separately rather than presenting a filled-in blank as the regulation's own text.

Reading the official wording. … is a blank the supplier fills in — not a truncated sentence.· [square brackets] mark a part printed only when it applies. · A slash offers a choice, as in POISON CENTER/doctor.
02 · Legal status
Where P334 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.

03 · On a label
P334 usually appears combined
CLP Annex IV defines combined statements as single label elements. P334 is a component of one of them — this is how you will actually see it printed.
| Code | Combined statement |
|---|---|
| P302+P334 | IF ON SKIN: immerse in cool water or wrap in wet bandages. CLP verbatim: IF ON SKIN: Immerse in cool water [or wrap in wet bandages]. |

Substances carrying P334
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.
