How to spot a gas leak
You should check your dispensing systems every day for faults by checking that all nuts and seals are tight and listening for hissing sounds. If you suspect that a leak has occurred, you must put into operation emergency gas procedures immediately.
You can check whether gas cylinder or gas equipment is leaking by applying a weak ammonia free soap solution. Any frothing or bubbling indicates that gas is leaking. Frost or condensation on a cylinder, or where the ‘O’ ring on a cylinder connecting hose is missing or damaged, can also indicate a leak, as can loss of pressure on the regulator gauge when the gas is turned off. If you suspect a minor leak has occurred, report this to a manager immediately and ventilate the cellar, making sure that someone knows that you’re going into the cellar and how long you are likely to take.
