Gas leaks in the home can be dangerous and potentially life-threatening. It is important to be able to detect gas leaks and know what steps to take if one is detected. Signs of a gas leak include a strong odor, hissing sounds near gas appliances, and dead plants or vegetation near gas lines. If you suspect a gas leak, evacuate the premises immediately and call the gas company or emergency services. Avoid using any electrical devices or open flames, as these can ignite the gas. Regularly inspect and maintain gas appliances and install a carbon monoxide detector for added safety.
A gas leak in your home is a serious matter due to the highly flammable nature of gas, which can lead to explosions and fires. It is important to swiftly locate and address any gas leaks.
Although some gas leaks may be obvious, others can be more subtle. It is just as vital to address small leaks as it is to address large ones, but it may be more challenging to locate the source of the leak when it is small. If you suspect a gas leak but are not certain of its location, do not waste time trying to find it. Instead, exit the building immediately and leave the door open. Once outside, contact the gas company to report the potential issue. Gas leaks are potentially hazardous, and it is best to leave the finding and fixing of the problem to the experts.
Understanding Your Gas System
It is critical to evacuate quickly if you suspect a gas leak instead of trying to locate it or turning off the gas. However, it is a good idea to have a basic understanding of your gas system, allowing you to shut it off if necessary or identify when something seems wrong.
The gas meter, where gas enters your home, is located outside the building. The gas pipe that brings gas from the gas company into your home is on one side of the meter, called the street side, and has a shut-off valve requiring a wrench to close. As a general rule, gas companies prefer that you avoid touching this valve. Closing this valve stops gas from entering your home.
The other side of the meter, known as the house side, has another pipe that carries gas from the meter to the interior of your home. There is also a shutoff valve on this pipe, which you should use whenever possible. This valve is typically a small lever that is open when parallel to the pipe. To close it, turn it 90 degrees so that it is perpendicular to the pipe.
Inside your home, metal piping carries gas through crawl spaces or along the basement ceiling, traveling horizontally until it reaches a gas appliance. A vertical tube called a drop line extends down from the horizontal pipe to the appliance if the appliance is below the main gas line. If the appliance is above the main gas line, the drop lines extend upwards instead and are known as risers.
Flexible metal supply tubes connect your gas appliances to the gas branch piping. These flexible tubes carry gas from the rigid pipes in your home to the appliance, allowing for some flexibility. Flexible connectors are not permitted to pass through walls, floors, or ceilings and are always visible behind your appliances. They are typically between 3 and 6 feet long.
The appliance’s gas intake becomes more accessible and provides some space to move the appliance away from the wall for maintenance due to the flexibility of this pipe. Often, there is another shutoff lever or valve just before this flexible pipe, allowing you to turn off the gas at the appliance.

Indicators of a Gas Leak at Home
Gas has a distinct and pungent sulfur smell (similar to rotten eggs) that is deliberately added to it. Since natural gas is invisible and odorless, gas companies add this smell to make it easy to detect a leak. In most significant gas leaks, the smell is intense and difficult to miss.
Unfortunately, minor gas leaks can produce a weak smell that is hard to notice. It is also possible to get used to the odor after prolonged exposure. For example, a slow leak may produce only a mild smell that you become accustomed to over time.
If you miss the smell, there are other signs to look for. One is the browning and dying of plants. Whether they are near your meter outside or indoor houseplants, vegetation will wither and die when exposed to a natural gas leak. You may also detect a hissing or whining sound or see a small white dust cloud near the leak area.
Your gas stove can also alert you to a problem in your home. The flames of your stove burners should be blue. If they are yellow or orange, there is an issue. Visibly cracked or broken gas lines, as well as an unexplained increase in your gas bill, also indicate an evident problem.
Outside, strange bubbles in a creek or nearby stream can indicate a gas leak. A spray of dirt rising into the air can also signify a leak. Although you cannot see the gas itself, the force of the leak is strong enough to disturb loose dirt, making it visible.
Gas Leaks and Their Effects on Health
Besides causing problems around the house, a gas leak can also affect your health. Physical symptoms such as dizziness, nausea, shortness of breath, and fatigue may occur when you are exposed to natural gas. Frequent headaches, nosebleeds, and a sore throat may also be observed. Some people may experience ringing in their ears, a reduced appetite, and chest pain.
Of course, all of these symptoms may indicate other health problems unrelated to gas. To identify gas as the cause, pay attention to when you get sick. If it happens frequently when you return home from being elsewhere or when you enter a specific room, a gas leak may be to blame. Keep an eye on your pets as well. They may experience many of the same symptoms.
What Not to Do in the Event of a Gas Leak
If you suspect a gas leak, do not hesitate. Trust your instincts and evacuate your family and pets from the house. Do not attempt to turn off the gas or fix a leak yourself. This is a task that should always be left to the professionals, regardless of how skilled you are at DIY.
When leaving a home during a gas leak, it’s important to avoid using any appliances or light switches as they can cause a spark and ignite the gas. If you have a minor issue, you can open your windows to air out the house, but if the gas odor is strong, do not open them as the friction could create a spark. It’s crucial to never light a cigarette, candle, or match and to never use a phone inside the home. Instead, walk to a safe place and call the gas company to report the leak.
Once the gas leak is reported, the gas company will send someone to inspect and fix the problem. However, it’s important to verify that the personnel are legitimate gas company employees and not imposters trying to gain access to homes. You can ask for identification and call the gas company to verify their presence. Gas leak detectors are also a smart addition to a home, as they will sound an alarm if a gas leak is detected. Carbon monoxide detectors, on the other hand, will not detect a gas leak as carbon monoxide is released only when gas burns.
Ways to Avoid Gas Leaks and Troubles
Gas leaks are inevitable but there are measures that can be taken to minimize the risks. The most effective way is to have experts inspect your gas lines and appliances annually. These inspections help identify potential issues and fix them before they escalate. During the inspection, request to have chimneys, flues or vents checked as well.
It’s also crucial to provide adequate ventilation space around gas appliances to prevent gas from accumulating around them. Always keep flammable chemicals away from gas lines and appliances.
Be prepared for emergencies by having a fire extinguisher readily available and an emergency plan in place. Ensure that every member of your household knows how to recognize the signs of a gas leak and what to do in case of detection. Evacuate immediately and call for assistance.
