I must be getting old! Can someone please remind me which gas (or mixture?) is contained in a pale pink cylinder?

It could be a number of things - it might be a welding mixture, or not. It might be a food grade inert gas, or not.

The colour coding is complex, with some having different colour stripes and shoulder colours.

Since there has historically been no universal colour system, and the 'popular' colour codes are currently in the process of changing, the advice is always to read the label.

Never rely on the colour code.

Paul,

Yesterday I received notification from Air Products about the new standard for colour coding of gas cylinders along with an identification chart.

The chart can be downloaded from www.airproducts.co.uk, click on the cylinder colour coding banner.

Regards

David

Thank you both

I continued searching after posting my query and eventually found the answer. The application was welding and the mixture was a shielding gas. I, too, have discovered the new colour scheme.

Hi,

I know you have found your answer (from your last post), but thought I would just add that the info I got from our gas suppliers, quotes that there is a new standard (EN 1089-3) which replaces the old BS349 standard for colour identification of gas bottles.

It should also be noted that the leaflet I got also says (as previously mentioned in this thread), 'colour codes are a guide only. Labels or collors should be used as the primary means of identification'.

Regards,

Liam Nolan
