Flame (GHS02)
The GHS pictogram for flammable hazards: flammable gases, aerosols, liquids and solids, and substances that ignite on their own, heat themselves or give off flammable gas in contact with water.
Easily confused with
- Flame over circle (GHS03)The GHS pictogram for oxidizers: oxidizing gases, liquids and solids.
- NFPA 704 fire diamondThe NFPA 704 hazard diamond: a sign on buildings, doors and tanks that tells firefighters and other emergency responders how severe a stored material's health, fire and instability hazards are, each rated 0 to 4, with any special hazard in the white section at the bottom.
- No open flame sign (P003)A red ring and diagonal bar across a lit match means open flames are forbidden where the sign is posted, and smoking with them. It is sign P003 in ISO 7010.
How to read it
It is GHS02. Canada’s WHMIS lists it for flammable gases, flammable aerosols, flammable liquids (categories 1 to 3), flammable solids, pyrophoric liquids and solids, self-heating substances and substances that emit flammable gases in contact with water. OSHA’s standard assigns it to flammable gases and flammable liquids, among others. In Great Britain it is called Flammable.
Also searched as: fire symbol, flammable symbol, GHS02.
These identify the hazard class a pictogram represents. For handling, storage and first aid, refer to the product's label and safety data sheet.
What it does not cover
Not every flammable product carries the flame. In Canada, flammable liquids in category 4, flammable gases in category 2 and aerosols in category 3 need no pictogram at all.
Look-alikes
The Flame over circle (GHS03) marks oxidizers instead. Britain’s Health and Safety Executive names the two pictograms Flammable and Oxidising.
