What to do if you Suspect a Gas Leak

Gregor's Plumbing & Gas Sunshine Coast

Gas leaks can be dangerous. If you smell gas you need to act quickly.

A gas smell may mean you are running low on gas. Check your cylinders and see if this is the case. If you have plenty of gas then you need to call in your plumber.

Turn Off the Gas

Turn off the gas supply at the cylinder before you call the plumber.

Turn off all appliances in your home including electrical appliances and light switches.  Switch off the power at the mains. Do not use your telephone as this could create a spark. Go outside and use your mobile phone to get help.

If you can you should turn the gas off at the meter. The meter will usually be located at the front or at the side of the house. It is a good idea to find out the location of the meter as a precautionary measure. The valve that isolates your gas supply can be found on the inlet of the gas meter and is a quarter valve turn. Turn the valve to the off position by rotating the handle 90 degrees from the vertical on position to the horizontal off position.  Next time your plumber is visiting ask him to show you how to do this in case of such an emergency.

Ventilate the House

The next thing you should do is create as much ventilation as possible. Open all doors and windows to let the fresh air in and the gas out. Gas is poisonous so act quickly. If the gas smell is overpowering you should vacate the premises. Do not use electrical fans to help ventilate the area.

No Flames

This seems like an obvious point but it is worth reiterating. You should light any naked flames at all including cigarettes. Gas fumes spread and any flames should be extinguished immediately. Never use a flame to try and find a gas leak.

If it’s Outside

If the gas smell is outside not inside you should immediately call an emergency line and give them an accurate description of your location. Don’t hesitate to do this. Some people think they may be making a fuss but in the case of leaking gas it is imperative that urgent action is taken to prevent possible disaster.


There are simple things you can do to minimise the chance of experiencing a gas leak. Make sure all gas appliances are installed by a suitably qualified professional. Always make sure you store flammable supplies well away from any gas appliances. This will help to prevent disaster in the case of a leak. Turn off all gas appliances before you go to sleep and before you leave your home. Don’t use outdoor gas appliances inside. Make sure gas cylinders are serviced at least every ten years.
