What are the Common Signs of a Gas Leak?
Natural gas is both colourless and odourless in its pure form, but gas distributors add a chemical (called mercaptan) to give it that strong, unmistakable rotten egg smell. While this odour is often the first clue, it’s not the only red flag when natural gas leaks happen.
Other signs to watch for include:
- Bubbles forming in puddles or damp areas above buried gas pipes
- Unexpectedly dry or dead grass and plants near gas lines
- Hissing or whistling sounds from gas appliances or pipe joints
- Pilot lights that flicker, won’t stay lit, or change colour from blue to yellow or orange
- A sudden spike in your gas bill
- Family members experiencing unexplained illness (see more on gas exposure symptoms below)
Whether your home uses natural gas or LPG, these symptoms can be easy to miss – especially things like bubbling water or dying plants.
That’s why regular gas appliance servicing is so important. With Metropolitan Heating and Cooling, you’ll receive expert maintenance and a Certificate of Compliance for peace of mind.
The Many Dangers of Gas Leaks
Gas leaks are more than just an inconvenience – they’re a serious safety hazard. Even a small leak can have major consequences if left unnoticed. The most obvious danger is the risk of fire or explosion. If gas builds up in an enclosed space and comes into contact with a spark or flame, it can ignite instantly.
But the dangers don’t stop there. Breathing in gas can lead to health problems, including dizziness, headaches, nausea and in extreme cases, unconsciousness or even death. Long-term exposure to gas leaks can be especially harmful to children, pets, and the elderly.
Carbon monoxide, often produced by faulty gas appliances, is another silent threat. It’s odourless and deadly, making it essential to stay on top of appliance maintenance and gas leak detection.
When it comes to your gas supply, it’s always better to be safe than sorry. If you suspect a leak, don’t hesitate – call the experts immediately.
