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 “Toxique par ingestion ou par contact cutané” and Mexico’s Spanish text is “Tóxico en caso de ingestión o en contacto con la piel”.
