Gas Purging FAQ

Gas purging is the introduction of an inert (non-combustible) gas into a closed system to prevent the chance of an explosion from air and an combustible gas mixing. Purging into service is conducted to push out any oxygen remaining in a system and replace it with an inert gas so when a combustible gas enters the system it doesn’t mix with the oxygen and form an explosive concoction. Purging out of service is the opposite, an inert gas is put into the system to push out combustible gas to prevent it mixing with oxygen when the system is shut down.le Description
Gas purging occurs for a variety of reasons, mainly to remove combustible gas or oxygen from the system to prevent an explosive reaction. It is also done to remove any impurities which may damage the system or affect its function, especially when a sensitive gas mixture is needed for operation.ordion Sample Description
Gas should be purged once a system has been installed but before the combustible gas is introduced to the system. It should also be purged if any work is being done on the systems gas pipes e.g. cutting into a pipe, removing a pipe or disengaging the system once use has ceased.
How long a gas purge takes depends on the size of the system, the larger the system the longer it will take. To find out about a specific system contact an engineer who should come to service the property and advise on an appropriate time span for the purge.
Purging is normally for commercial properties only unless the domestic property is especially large. To purge up to 1 cubic metre of gas you need a TPCP1a qualification and to purge over 1 cubic metre you need a TPCP1 qualification.


A gas tightness test is a annual legal requirement for commercial boilers to ensure that your gas installation is safe. It is generally carried out during your annual gas safety certification, but can also be undertaken if you believe you may have a gas leak somewhere in the system.

The Gas Safety (Installation and Use) Regulations 1998 make it clear that business owners are responsible for ensuring that any gas installation located on their premises is safe to use. Call us today on 0207 9989 005.
