Precautionary · PreventionPhysical

P211 is the GHS precautionary statement “Do not spray on an open flame or other ignition source”. UN GHS Annex 3 assigns it to Aerosols (chapter 2.3), Category 1, 2 and Chemicals under pressure (chapter 2.3), Category 1, 2. The English wording is the same as UN GHS Rev.11 in US OSHA, EU CLP and Canada. Canada’s official French text is “Ne pas vaporiser sur une flamme nue ou sur toute autre source d'ignition” and Mexico’s Spanish text is “No vaporizar sobre una llama al descubierto o cualquier otra fuente de ignición”. In the UN GHS Rev.11 label matrix it is used with 5 hazard statements (UN only).
