H302+H312+H332 is the GHS hazard statement “Harmful if swallowed, in contact with skin or if inhaled”. It is used for Acute toxicity, oral (chapter 3.1), acute toxicity, dermal (chapter 3.1) and acute toxicity, inhalation (chapter 3.1), Category 4. The English wording is the same as UN GHS Rev.11 in EU CLP and Canada. OSHA does not list the combined wording but allows combining hazard statements. Canada’s official French text is “Nocif en cas d’ingestion, de contact cutané ou d’inhalation” and Mexico’s Spanish text is “Nocivo en caso de ingestión, en contacto con la piel o si se inhala”.
