A Home Owner's Guide to Gas Leaks

Natural gas heats your home and powers your appliances efficiently. However, gas can pose a health and safety risk if leaked into your home or exposed to heat or flame.

To protect your home and family, you must know how to act should a gas leak occur. In this blog, we discuss the signs of a gas leak, how you should respond when you suspect a leak and how you can prevent future leaks.


Common Signs of a Gas Leak


While gas leaks can be dangerous, they also come with a distinct set of warning signs that can help homeowners identify the issue quickly. Common signs of a gas leak include the following.


Changes in Breathing


Large gas leaks can dramatically change the amount of oxygen in your home. When this alteration happens, you may notice heavy or irregular breathing. This symptom appears first in pets, children and the elderly.


Dizziness or Nausea


Exposure to gas can cause headaches, dizziness and nausea. If your symptoms immediately improve when you get some air, consider the possibility of a gas leak.


Foul Odour


Suppliers treat natural gas to give it a distinct sulphuric smell. If you notice the smell of rotten eggs, especially around a gas appliance, assume you have a gas leak.


Landscaping Changes


If the leak becomes large enough or develops in a supply pipe outside your home, you may notice changes to your outdoor landscaping. These changes include dead vegetation in a localised area, loose debris blowing through the air in a small area and bubbles in puddles.


Unusual Noise


If you have a gas leak, you may hear a whistling or humming noise.

As you use your gas appliances, pay attention to each machine's normal behaviour. If you notice a change in pilot light colour or a pilot light that doesn't stay lit, this sign may indicate the presence of an early leak.


How to React to a Gas Leak


If you suspect that you have a gas leak, take action immediately by isolating the gas supply or gas maters. The safest course of action will depend on how large of a leak you have. Follow these guidelines.


Large Leak


If you experience sudden medical symptoms, loud whistling or a dramatic change in smell, assume you have a large leak. Do not attempt to address this issue yourself. Shut down the gas supply at your gas meter.

Instead, leave the premises and call a gas fitter or your utility company from a safe place.


Small Leak


If you notice changes to a pilot light or the faint smell of sulphur, take the following steps. First, open the doors and windows in your home for ventilation.

Then, check that all burners and gas appliances are off. If you can do so easily and confidently, turn off your gas supply.

Finally, contact a gas fitter who can determine the leak's location.

If you cannot gauge the size of the leak, proceed as if you have a large leak.

How to Prevent Gas Leak Formation


The best way to minimise the risk associated with gas leaks is to take precautions against them. Use the following strategies to reduce the risk of gas leaks.


Schedule Routine Maintenance


Your gas system needs upkeep just like your plumbing and HVAC systems. Schedule an annual inspection and handle any necessary repairs right away.


Trust a Certified Gas Fitter


When you have gas fitting done, whether it's a repair or a new installation, always choose a certified technician.

Follow these guidelines to ensure that your gas system powers your home without posing any danger to the people and belongings you love.
