Cylinder shoulder – European standard colour coding

The colour applied to the shoulder, or curved part at the top of the cylinder, signifies the European standard colour coding.

The aim of the new standard (EN 1089-3), which has replaced the old cylinder colour scheme (BS349), is to help improve safety standards within the gases industry.

A number of gases have been assigned a specific colour and some of these are shown below:
