Gas can be explosive, so safety is paramount when dealing with a leak. While a gas leak doesn’t cause an immediate threat, there is a strong risk of a fire or explosion if left unattended, so every homeowner must know what to do in the event of a leak. 

When it comes to gas, early detection is the key to reducing the risk of an explosion, so we have put together this guide to help you detect a gas leak quickly. If you suspect gas is leaking, we’ll show you what to do and who to call to get it sorted quickly. 

How to detect a gas leak

Natural gas is completely odourless, but mercaptan is added to the gas during production to give it a pungent smell. In most cases, the smell will be the first thing you notice when a leak occurs, but you may also hear a hissing sound from the pipes.

If the leak occurs inside the property, you may also experience the following symptoms: lightheadedness, dizziness, difficulty breathing, headache, eye/throat irritation and nausea. Anyone suffering from asthma may experience these symptoms first. 

What does gas smell like?

The mercaptan added to the gas has a very distinctive sulfur-like smell. Some people say it smells like rotten eggs. This smell is designed to be repugnant so that you notice it immediately. The smell will be noticeable if only small amounts of gas are released, giving you plenty of time to call a plumber before the fumes reach dangerous levels.

What to do if you smell gas

If you smell gas inside the home, there are some precautions you can take to reduce the danger. 

Things to do

• Extinguish any open flames

• Open all doors and windows 

• Leave the property as soon as possible

• Call our emergency helpline on 0419 998 068 

Things NOT to do

• Do not use a fan to assist with ventilation

• Do not plug or unplug any electrical appliances

• Do not switch on any lights, including flashlights, or use a telephone

• Do not light any matches or cigarette lighters

• Do not re-enter the home until it has been inspected by a licensed gas fitter

Who to call for a gas emergency

Gas leaks fall into two categories, those which occur inside and outside the home. The process for dealing with each scenario is different, so let’s take a look at them individually. 

Outdoors

If you smell gas outside, this is likely to be caused by a leaking gas main. You should report this immediately by calling the emergency gas helpline on 1800 GAS LEAK (1800 427532). 

Indoors

If you smell gas inside your home, this is likely caused by a faulty appliance. In this case, you should turn the gas off at the meter. If the smell stops, you should call our emergency plumber helpline on 0419 998 068 and we’ll send an engineer out to investigate. 

If the smell doesn't stop, this indicates a problem with the gas main and you should call the emergency gas helpline on 1800 GAS LEAK (1800 427532).
