P103 · Precautionary statementRead carefully and follow all instructions.
P103 is the GHS precautionary statement “Read carefully and follow all instructions”. UN GHS Annex 3 lists it as a general precautionary statement, to be used as appropriate (Table A3.2.1). The English wording is the same as UN GHS Rev.11 in EU CLP and Canada. Not adopted in US OSHA. Canada’s official French text is “Lire attentivement et appliquer toutes les instructions” and Mexico’s Spanish text is “Leer la etiqueta antes del uso”.
