How to Recognise a Dangerous Gas Leak

Because a natural gas leak in your home can be detrimental to your family’s health, and extremely dangerous in certain situations, it’s important to be aware of the first signs that gas is present. These can be difficult to spot if you don’t know what you’re looking for, but once you notice them, you should seek emergency assistance immediately.


A very distinct odour. People usually compare the smell of a gas leak to rotten eggs or sulphur. It’s a strong smell that’s very noticeable and often, cannot be attributed to anything else in the house.


Unusual noises. Squealing or hissing sounds might not be present with a gas leak, but if you do notice them, they could help you determine where a gas leak is located.


Dead or discoloured vegetation. If the plants around your pipeline have been killed or look like they’re dying, it could be because they’re experiencing the negative effects of a nearby gas leak.


Strange frozen ground. When the ground near the pipeline has unexplained ice or frost around it, you should assume that there may be a gas leak and seek professional help quickly.


Bubbling standing water. As strange as this sounds, this could be a sign of a nearby leak, especially if the bubbles are continuously present without any other kind of explanation.

If you spot any of these signs in your home, you should avoid turning on any electric appliances, and attempt to shut off the main gas supply valve if you can. Then, gather everyone in the house and evacuate as quickly as possible. You may need to do this on foot in order to avoid turning on cars and other electronic or gas-fuelled items.
