Flame pictogram (GHS02)
The flame pictogram (GHS02) is assigned to twelve hazard classes in UN GHS Rev.11: flammable gases; aerosols; chemicals under pressure; flammable liquids; flammable solids; self-reactive substances and mixtures; pyrophoric liquids; pyrophoric solids; self-heating substances and mixtures; substances and mixtures which, in contact with water, emit flammable gases; organic peroxides; and desensitized explosives. Of the 24 class and category rows below, 15 take Danger and nine take Warning. They call for 24 hazard statements (H206, H207, H208 and others). OSHA's Figure C.1 lists it for flammables, self-reactives, pyrophorics and more, and EU CLP Annex V gives it eleven entries. Under EU CLP it becomes optional when the exploding bomb applies, unless more than one of those pictograms is compulsory, and when it applies the gas cylinder becomes optional (Article 26(1)(a) and (e)).

- Organic peroxides
- Desensitized explosives
EU CLP
- Flammable gases, categories 1A, 1B (2.2)
- Aerosols, categories 1, 2 (2.3)
- Flammable liquids, categories 1, 2, 3 (2.6)
- Flammable solids, categories 1, 2 (2.7)
- Self-reactive substances and mixtures, Types B to F (2.8)
- Pyrophoric liquids, category 1 (2.9)
- Pyrophoric solids, category 1 (2.10)
- Self-heating substances and mixtures, categories 1, 2 (2.11)
- Substances and mixtures which in contact with water emit flammable gases, categories 1, 2, 3 (2.12)

- Desensitised explosives, categories 1 to 4 (2.17)
Under Article 26(1)(e), if GHS02 applies, GHS04 is optional.
Canada WHMIS (HPR)
Schedule 3, item 1: Flame. Used for each HPR category (Parts 7 and 8) that GHS Rev.7 Annex 3, section 3 assigns this symbol to (s. 3(1)(c)), with the Schedule 3 pictogram in place of the symbol (s. 3(3)). Schedule 5 covers only the HPR-specific classes (s. 3(1)(d)). For chemicals under pressure the HPR uses GHS Rev.8 instead (s. 3(1)(c.1), (c.2)).
Mexico NOM-018-STPS-2015
Spanish name in NOM-018 Appendix B: “Llama”. Table B.3 lists the categories that take it.
Precedence rules that involve GHS02
UN GHS Rev.11, 1.4.10.5.3.1
- For substances and mixtures covered by the UN Model Regulations, precedence of symbols for physical hazards follows the Model Regulations. In workplace settings the competent authority may require all physical hazard symbols.
EU CLP, Article 26(1)
- (a) If GHS01 applies, GHS02 and GHS03 are optional, except where more than one of them is compulsory.
- (e) If GHS02 or GHS06 applies, GHS04 is optional.
