About ISO Safety Symbols
ISO Safety Symbols is the look of a registered-symbol sheet: white plate, coloured geometric field, solid black pictogram. Shape carries the message before colour does — circle with a diagonal bar forbids, triangle warns, filled circle commands, square reassures.
Five safety colours are fixed to published RAL references and never drift. Figures are constructed on the ISO 3864-3 grid, not drawn. Words live on a supplementary panel beneath the sign, never inside it.
