A black exclamation mark in a red-bordered diamond, the GHS symbol for lower-level health/physical hazards or irritation.
Also known as: Irritant pictogram, GHS07
One of nine official GHS pictograms, warning of comparatively less severe hazards — skin/eye irritation, skin sensitisation, acute toxicity at a lower severity band, narcotic effects, or ozone-layer harm.
Warns of lower-severity hazards, including skin or eye irritation, skin sensitisation, acute toxicity (lower severity category), narcotic effects, respiratory irritation, or harm to the ozone layer.
This pictogram covers several distinct, lower-severity hazard classes under one shared symbol — the specific hazard is stated separately on a label's hazard statement, not by the pictogram alone.
Appears on the outer packaging of a supplied chemical and again in section 2 of its safety data sheet, so a reader who has the sheet can check the label against it. On a product sold in the European Union or Great Britain it is not decoration: the supplier is required to show the pictogram the classification calls for.

Covers acute toxicity category 4, skin and eye irritation, skin sensitisation, specific target organ toxicity from a single exposure category 3, and — in the European Union — hazard to the ozone layer. One pictogram can stand for several distinct hazard classes, which is why the pictogram alone never tells you the whole story — the hazard statements printed beside it do.

Is a *supply* label. A drum or tank in transit carries a differently shaped and coloured label for the same hazard under the transport rules, and the two schemes coexist — a package can lawfully carry both at once.

Replaced two European marks at once rather than one, and looks like neither of them. The orange-square scheme used a black St Andrew's cross for both harmful (Xn) and irritant (Xi), and that image has no successor: a reader holding an old bottle marked with a cross and a new one marked with an exclamation mark is looking at the same class of hazard drawn in an entirely different way.

A black exclamation mark, inside a diamond outlined in red.
Both enclose an exclamation mark in a bordered shape. This is a red-bordered diamond on chemical packaging with a defined set of hazard classes; the general warning sign is a yellow triangle on signage meaning unspecified caution.
