A black flame icon in a red-bordered diamond, the GHS symbol for flammable hazard.
Also known as: Flammable pictogram, GHS02
One of nine official GHS pictograms, warning that a substance or mixture is flammable — including flammable gases, liquids, solids, aerosols, or substances that emit flammable gas on contact with water.
Warns that a substance or mixture is flammable (gases, aerosols, liquids or solids), self-heating, pyrophoric, or emits flammable gas on contact with water.
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 flammable gases, aerosols, liquids and solids, and also self-reactive substances, pyrophoric liquids and solids, self-heating mixtures, substances that emit flammable gas on contact with water, and organic peroxides. 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.
Contexts: Packaging
The European scheme it replaced used an orange square with a black symbol and a letter code. Orange-square labelling stopped being lawful for the supply of mixtures in the European Union on 1 June 2015, so a container still showing one is either old stock or outside the scheme. For flammability the predecessor was the orange square flame, coded F for highly flammable and F+ for extremely flammable.

Orange square flammable symbol (pre-2015 European supply label)
The predecessor mark under the European dangerous-substances directives: the same black flame, set on an orange-yellow square rather than a red-bordered white diamond, and accompanied by the letter code F or F+. Withdrawn for supply labelling on 1 June 2015.
A black silhouette of a flame, inside a diamond outlined in red.
A flame alone means the substance burns; a flame over a circle means it makes other things burn.
