AS 4484-2004 – Gas Cylinders for Industrial, scientific, medical and refrigerant use – Labelling and colour coding

Australian Standard (AS 4484-2004) defines the labelling and colour coding for gas cylinders.  ANZIGA members undertook a coordinated program to convert all medical gas cylinders to the required white body colour. The cylinders were also marked twice on the shoulder of the cylinder with a 'N' to indicate that the colour coding was new as required by the Australian Standard.

The new colour scheme is completed for all medical oxygen cylinders in Australia and New Zealand is now completed.

Standards Australia, who is responsible for the Australian Standard, has recently published a 'ruling' on the use of the 'N' on medical gas cylinders.  This ruling can be found on their website and in the revised standard.

The ruling allows the 'N' to now be removed as the colour conversion is now complete.

ANZIGA members will be progressively removing this marking.
