Gas Leak Warning Signs
Gas Leak Warning Signs Every Homeowner Should Know
Gas leaks are rare, but they're one of the most serious safety hazards a homeowner can face. Knowing the warning signs could save your life. Here's what every Blue Mountains and Western Sydney homeowner should know.
The Smell of Rotten Eggs or Sulphur
Natural gas is naturally odourless. Gas companies add a chemical called mercaptan, which produces a distinctive rotten egg or sulphur smell, specifically so leaks can be detected by smell. If you notice this smell inside your home — particularly near gas appliances, the meter, or in enclosed spaces — take it seriously. Even a faint smell warrants investigation.
A Hissing or Blowing Sound Near Gas Lines
A hissing, whistling, or blowing sound near a gas appliance, meter, or gas line can indicate gas escaping from a pressurised pipe. This is a serious sign and should be treated as an emergency. Don't attempt to locate the source yourself — leave the building and call a licensed gas fitter immediately.
Dead or Dying Vegetation in a Dry Patch
An unexpected dead patch of grass or garden in an otherwise healthy lawn can indicate an underground gas leak. Gas displaces oxygen in the soil, killing plant roots. If you notice an unexplained dead area above where you know gas pipes run, call your gas supplier or a licensed gas fitter to investigate.
Bubbling in Wet or Flooded Areas
After heavy rain, if you notice bubbling in puddles or waterlogged areas of your garden near gas lines, this can indicate a gas leak. Gas escaping through water-saturated soil creates visible bubbling at the surface. Don't attempt to investigate — call for help.
Physical Symptoms: Headaches, Dizziness, Nausea
Carbon monoxide — produced by incomplete combustion from faulty gas appliances — is odourless and colourless, and far more dangerous than a gas leak. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, confusion, and fatigue that improve when you leave the building. If multiple household members are experiencing these symptoms, evacuate immediately and call emergency services. Install a carbon monoxide detector — they're inexpensive and could save your life.
What to Do If You Suspect a Gas Leak
Do not turn any electrical switches on or off. Do not use your phone inside the building. Do not light any flames. Leave the building immediately, leaving doors open as you go. Once outside, call your gas supplier's emergency line or a licensed gas fitter. Do not re-enter until the property has been inspected and cleared by a professional.
