Small Gas Cylinder Leaks

Bar and Cellar Safety

A small gas leak may occur if, for example, a nut is not tightened or a gas seal is faulty.

If you suspect a small gas leak has occurred, take the following steps:

First:

  • ventilate the cellar by opening all doors and cellar flaps (ensure there are barriers around the open flaps)

  • prevent anyone from entering the cellar

Then enter the cellar:

  • tell someone that you are about to go into the cellar, why, and how long you think you will be there

  • turn and close off the carbon dioxide or mixed gas cylinder valve

  • if possible, isolate the problem by switching off the individual secondary regulator valve, or checking connections if the leak is upstream of the secondary valves

  • spray the cellar floor with water (carbon dioxide is very soluble in water)

  • when you return from the cellar, tell the person you informed earlier

  • let someone know whether it is now safe to enter

  • If at any time you feel the effects of increased carbon dioxide concentration (feeling short of breath, breathing faster), leave the cellar immediately and call for assistance.

  • Bar and Cellar Safety - Dispense Gas Cylinder Test Date Rings [pdf / 63KB] By law, all dispense gas cylinders have to be regularly inspected and tested to ensure they continue to be totally safe for the high pressures contained inside them. Every cylinder should have a coloured ring attached to the valve indicating when it is due for removal and testing by the gas provider. This is routinely changed every 10 years. The table in this document indicates when the cylinder should be tested by law.
