Early cylinders were coloured as their maker saw fit, usually black, perhaps with a white top for oxygen. The Americans first achieved standardisation, but other countries do not follow American Standards. Australia follows the colour-scheme of the British Oxygen Corporation. The body is coloured individually for each gas, viz: compressed air, grey; carbon dioxide, brown; oxygen, black; nitrous oxygen, blue’ cyclopropane, primrose-yellow’ ethylene, mauve. Panels of other colours may appear on the body, but indicate technical points of cylinder-design and do not concern the anaesthetist.
