A new standard governing the colour-coding of transportable gas cylinders is coming into force across Europe. As a result, many UK gas cylinders will receive a fresh coat of paint.

The aim of the new standard (EN 1089-3), which has replaced the old cylinder colour scheme (BS 349), is being introduced to help improve safety standards within the gases industry.

What is happening

• The cylinder shoulder (curved part of the cylinder) will be painted with a specific colour in line with the new standard
• All UK gas companies will adopt the standard colour scheme for the shoulder colour of gas cylinders
• It is important to note that the cylinder body can be any colour and will be different for each gas company

Why is it happening

• The change in colour is to improve safety and ensure consistency within the gases industry
• By using a colour standard, the contents of the cylinder will be more easily identified when the label is not clearly visible in emergency situations

When will this be happening

• BOC has already painted argon, Argoshield, nitrogen and oxygen, with a progressive roll-out for the remainder of the cylinders
• Carbon dioxide is planned to be repainted in summer 2006

What does this mean to me

• As the cylinders are repainted, both old and new cylinder colours will be in circulation
• You must always read the label. It is the primary method of identifying the cylinder contents
• The cylinder shoulder colour should be the secondary means of identifying its contents
