Gas leaks are extremely serious and require urgent action to protect yourself and your family members.
If you smell a natural gas odor, hear the hissing sound of gas escaping or see other signs of a leak: IMMEDIATELY EVACUATE the area, and from a safe location either call 911 or SoCalGas at 1-800-427-2200.
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.
A gas leak is when natural gas leaks from a pipeline and then into an area where it shouldn't be. Leaks are considered very dangerous since they can build into an explosive concentration. They can kill vegetation and trees, cause explosions and fires, and might release greenhouse gases into the atmosphere.
Everyone in the home should leave the building immediately and regroup at a pre-chosen safe place. This limits your exposure to the gas and puts distance between you and the home in case the gas leak ignites. Leave the doors and windows open.
After the leak has been repaired, you can open the windows to let your home air out. This can take up to several hours. Don't stay indoors until you are certain that the gas is gone.
The acceptable leak rate does vary depending on whether the source is domestic or commercial, but a leak rate of 0.000 5 m3/h per m3 of space is generally acceptable in well ventilated areas.
Natural gas leaks are particularly likely to cause smells in small, enclosed areas where gas can build up. If the leak is outside, the smell may seem to come and go as the breeze blows it away. The other big sign to look out for is a strange noise.
Natural gas explosions are not only devastating but often deadly. A small leak, if exposed to a spark or flame, can trigger an explosion powerful enough to cause huge fires and significant loss of life. The energy blast of the explosion can damage or even destroy houses and buildings.
If there is a gas smell but no leaks, it could be the lingering propane odor due to poor ventilation or it coming from your neighbor. The dirty sewage system, contaminated well, or rotten garbage (like veggies, dead animals, residual foods, etc.) might also be the source of the smell.
DO NOT smoke, or make a spark or flame. DO NOT turn on any electrical switches, appliances or lights as an electrical charge could create a spark. DO NOT raise or lower the windows or use any phone inside your home. DO NOT open your garage door.
Gas leaks can be extremely dangerous. A fire, explosion, property damage or serious bodily injury could occur when natural gas leaks from an appliance, damaged pipeline or gas meter. Be alert to and check for any of the following signs if you suspect a gas leak.
After your gas leak is fixed, your house might still have a strong gas smell. Now you can open your windows and doors to let your home air out. You want to air out your house for anywhere between 15 minutes and a few hours. Do not assume that all the gas has dissipated once the smell disappears.
Alert area occupants and have them evacuate the area. Call 911. Turn off ignition sources. If possible, ventilate the affected area (only if it can be done safely and only if the leak is vented to the outside) prior to leaving the area.
They can even go on for months undetected. But if there's a significant amount of gas escaping from your system, it can cause a spike in your gas bill.
Cost to Repair a Gas Leak
cost $120 to $250, though you should plan for financial surprises. For example, if drywall is covering up a leaky gas pipe, you will have to hire a drywall contractor to replace the areas knocked out by the plumber. This will set you back $270 to $760.
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.
Inhalation: A natural gas leak in an outdoor environment is usually not concentrated enough to cause symptoms. A leak into a small-enclosed space can result in a lack of oxygen in the air and symptoms of hypoxia. These include headache, decreased vision, fatigue, shortness of breath and loss of consciousness.
A natural gas leak affects your oxygen intake, causing you to feel unwell and putting your life at risk. Common short-term symptoms of exposure to natural gas include: Headaches.
The odor makes natural gas easy to detect and can alert the public of a natural gas leak and help avoid a potentially dangerous situation. “Training your nose to identify the rotten eggs odor of mercaptan is the best way to detect a natural gas leak,” said Amy Spiller, president, Duke Energy Ohio and Kentucky.
Exposure to a slow gas leak in your house or apartment may cause deadly symptoms including sickness, weakness, nausea, suffocation, and headaches. If you feel sick or abnormal, immediately call an ambulance to confirm if you have been exposed to gas poisoning.
It's normal for a faint odor to remain after lighting a stove or if the pilot light in a hot water heater, gas fireplace or other appliance goes out. Nonetheless, any possible leak must be taken seriously, especially if the odor is strong, persistent, or accompanied by a hissing sound.
If you smell gas, call the National Gas Emergency Service immediately on 0800 111 999 or via textphone (minicom) on 0800 371 787.
