P250 is the GHS precautionary statement “Do not subject to grinding/shock/friction/…”. UN GHS Annex 3 assigns it to Explosives (chapter 2.1), Category 1, 2A, 2B, 2C. The English wording is the same as UN GHS Rev.11 in EU CLP and Canada. The wording differs in US OSHA. Canada’s official French text is “Éviter les abrasions/les chocs/les frottements/....” and Mexico’s Spanish text is “Evitar abrasiones / choques / fricciones /...”. In the UN GHS Rev.11 label matrix it is used with 4 hazard statements (UN only).
