Colour Coding
Different countries have different gas colour codes but attempts are being made to standardise the colours of cylinder shoulders:
- Colours of cylinders for Medical gases are covered by an International Organization for Standardization (ISO) standard, ISO 32; but not all countries use this standard.
- Within Europe gas cylinders colours are being standardised according to EN 1089-3, the standard colours applying to the cylinder shoulder only; i.e., the top of the cylinder close to the pillar valve.
- In the United States, colour coding is not regulated by law.
The user should not rely on the colour of a cylinder to indicate what it contains. The label or decal should always be checked for product identification.

Famous quotes containing the word colour:
“Iconic clothing has been secularized.... A guardsman in a dress uniform is ostensibly an icon of aggression; his coat is red as the blood he hopes to shed. Seen on a coat-hanger, with no man inside it, the uniform loses all its blustering significance and, to the innocent eye seduced by decorative colour and tactile braid, it is as abstract in symbolic information as a parasol to an Eskimo. It becomes simply magnificent.”
—Angela Carter (1940–1992)
