A Gas Line Leak Can Be Deadly

A gas line leak can be deadly! Call Alberta Indoor Comfort right away if you suspect a leak!
Every year people die due to gas leak related problems. Whether it's carbon monoxide poisoning or explosions, a gas leak is nothing to fool around with. If you suspect you have a gas leak in your home, it's essential that you diagnose the problem quickly and have it repaired for the safety of you and your family. Turn to the pros at Alberta Indoor Comfort (previously Sears) to request immediate service.
As mentioned, a gas leak isn't something to ignore. But how do you know you have a gas leak? Here are the telltale signs.
If you suspect that gas is leaking, it's imperative you call a professional gas line leak repair company for help before someone gets hurt.
There are a variety of dangers that coincide with a gas leak in the home, and none of them are to be taken lightly if you identify that you have a leak. The greatest threat is of a fire or explosion. Natural gas is highly combustible, and if the leak is large enough, simply turning on a light switch could be enough to ignite an explosion. The other danger of a gas leak is carbon monoxide poisoning. Inhaling small amounts of natural gas can cause nausea or headaches. As you inhale more and more gas, you get flu-like symptoms, dizziness, blurred vision, and fatigue. If you feel any of these symptoms, call emergency medical services right away and call a gas line leak detection company to pinpoint the leak and stop it.
Gas Leak Emergency Protocol
Do not delay. Do not investigate. Follow these steps in order.
Leave Immediately
Get everyone out of the building. Do not stop to gather belongings. Do not turn any lights, switches, or appliances on or off — a single spark is enough to ignite gas.
Call from Outside
Once you are a safe distance from the building, call ATCO Gas emergency line and AIC from outside. Do not re-enter for any reason until the all-clear is given by emergency services.
Stay Out Until Cleared
Gas emergency response requires professional equipment and certified assessment before anyone re-enters. Our gasfitters work with ATCO and emergency services to locate the source, isolate the leak, and make the space safe.
Ventilate Only If It Doesn't Delay You
If you can open a door or window on your way out without slowing down, it may help disperse the gas. Never stop to search for the leak, and never let this delay your exit — getting everyone outside safely comes first, every time.
Know the Signs — Even Without an Obvious Smell
Rotten-Egg Smell
Natural gas is odourless by nature. Mercaptan is added specifically to give gas its distinctive rotten egg smell — a deliberate safety feature. If you smell it, take it seriously every time.
Hissing Sounds
A hissing or whistling sound near a gas line, appliance, or meter may indicate gas escaping under pressure. This is an audible sign of a potentially serious leak.
Dead or Dying Vegetation
Underground gas leaks can kill or discolour vegetation in unusual patterns above the pipe. A sudden unexplained dead patch in your lawn near a gas line is a warning sign worth investigating.
Dust or Disturbance Near a Leak
A leak can sometimes stir up dust or visible disturbance in the soil or around a fitting. If you notice unexplained dust, bubbling, or disturbed ground near a gas line or meter, treat it as a possible warning sign and call us.
The Real Dangers of a Gas Leak
A gas line leak can be deadly. Every year, people are seriously hurt or killed by gas leak-related problems — whether from carbon monoxide poisoning or an explosion. If you suspect a gas leak in your home, diagnosing it quickly and having it repaired by a licensed professional is essential for your family's safety.
Fire & Explosion Risk
Natural gas is highly combustible. If a leak is large enough, something as small as flipping a light switch can generate the spark needed to ignite an explosion — which is exactly why we tell customers never to touch switches, appliances, or lighters on the way out.
Carbon Monoxide & Gas Poisoning
Inhaling small amounts of natural gas can cause nausea or headaches. As exposure builds, symptoms progress to flu-like feelings, dizziness, blurred vision, and fatigue. If you or anyone in the home feels these symptoms, call emergency medical services immediately and call our gasfitters to locate and stop the leak.
Take These Steps If You Suspect a Gas Line Leak
Knowing how dangerous a natural gas leak can be, follow these tips if you think you have a leak.
- If you smell gas, open your doors and windows to ventilate the house
A gas leak can sometimes be hard to detect if it happens outside the house. Watch out for plants or shrubbery that have changed color because that could be a sign of a gas leak. Whatever you do, don't try and fix the leak yourself. Get to safety and call a professional gas line leak repair company and let them handle it.

Gas Leak Questions
What should I do if I smell gas?
Leave immediately without switching anything on or off. Call from outside — dial ATCO's emergency line (1-800-511-3447) and AIC at (587) 792-1476. Do not re-enter the property until emergency services have cleared it. This is not optional — gas leaks can ignite from a single spark.
What causes gas leaks in Calgary homes?
Common causes include corroded or aging gas lines, loose or improperly sealed fittings at appliance connections, physical damage to underground service lines, and deteriorated flexible connectors on stoves, fireplaces, or furnaces. Post-renovation damage is also a risk when contractors don't identify and protect gas lines in walls or floors.
Can I detect a gas leak myself?
You can detect the smell of mercaptan (the additive used in natural gas) and listen for hissing sounds. What you cannot safely do is locate the precise leak point or verify that a repaired line is fully sealed — that requires certified equipment and a licensed gasfitter. Never use a lighter or flame to try to find a leak.
How is a gas leak found and fixed?
Our technicians use combustible gas detectors to identify the leak source — checking appliance connections, fittings, flex lines, and supply lines. Once found, the affected section is isolated and repaired or replaced. All repairs are pressure-tested before the gas supply is restored, and the completed work is documented for your records.
