P210 is the GHS precautionary statement “Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking”. UN GHS Annex 3 assigns it to 13 hazard classes. The English wording is the same as UN GHS Rev.11 in US OSHA, EU CLP and Canada. Mexico’s Spanish text is “Mantener alejado del calor, chispas, llamas al descubierto, superficies calientes y otras fuentes de ignición. No fumar”. In the UN GHS Rev.11 label matrix it is used with 29 hazard statements (UN only).
