When you're looking for gas leak signs in your home, keep in mind that it might not have physical signs or smells. You can find a damaged gas pipe, dead houseplants, and if a smell is present, it'll be rotten eggs and sulfur. Near the gas line, you might see a white or dust cloud, and a whistling or hissing sound.
No, carbon monoxide (CO) alarms cannot detect natural gas leaks. They are designed to detect the presence of carbon monoxide, a poisonous gas formed during incomplete combustion of fuels like oil, gas, propane, and wood.
Severe leaks can cause this problem in just five minutes. The EPA states that exposure to concentrations of nine ppm or more for eight hours is enough to produce harmful health effects for at-risk individuals. Exit the property and call 911 if you suspect your home has a gas leak.
Homes with natural gas have a main shut-off valve typically called the “street-side valve.” It is located just before the gas meter and looks like a rectangular nub. For single-family houses, the gas meter is typically located outside of the house on the side or in the back.
Do not open windows and doors if you smell gas outside your home. Natural gas is lighter than air, so opening windows and doors will diffuse the gas to outside of your home. DO NOT use any open flame nor touch any switches, including exhaust fan, kitchen fan, and light switches.
A good way to check whether you have a gas leak is to perform the 'bubbles test' with soapy water. Simply mix some dish soap with water, and spray or put the solution in the area you think is leaking. If you start to see bubbles showing up, then it's an indication that you might have a gas leak.
Gas leaks are subtle in smell but very obvious in bills. They can even go on for months undetected.
Gas leaks can often be detected by smell thanks to the addition of mercaptan. Gas is a naturally odourless substance, but the completely harmless artificial smell is added to make it more detectable.

We locate gas leaks by inducing helium into the gas lines and using a sensitive helium “sniffer” to identify where walls may need to be opened if the leak is not found at any exposed section of pipe. Sometimes we can get hits via gaps in the walls around outlets and switches or coming up through the floor upstairs.
In addition to having a distinct smell, natural gas leaks are often visual, causing bubbling water, blowing dirt or dead vegetation. You may also see sinkholes or exposed pipe. It's also possible to hear a hissing sound near a natural gas line or meter.
On a residential property, the gas meter will be likely located on an exterior side of the house. If you suspect a gas leak, head straight to the gas meter to shut off the gas to your entire home until the specific location of the leak can be pinpointed.
Heating a house is typically what uses the most gas in residences, followed by water heating, cooking and drying clothes. In fact, some 60% of residences in the U.S. use natural gas for these types of appliances and tasks.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
Here's what you should DO if you smell gas: DO leave the home, building, or area of the suspected leak. Get to a safe area as quickly as possible. After leaving your home, DO call the 24-hour emergency number for Peoples at 1-800-400-4271, or call your local emergency response number.
Detector Options
Some manufacturers of carbon monoxide detectors offer combination or 3-in-1 detectors to alert when carbon monoxide or an explosive gas such as natural gas or propane is detected.
