Anything electric creates a spark that could ignite a high concentration of natural gas. Avoid turning on any switches, electronics, or gas appliances while you suspect a leak. Avoid using lighters or anything with an open flame. Don't search for a gas leak with a flashlight or any other light source.

Can I use a lighter to check for a gas leak?

Not everyone has at their disposal natural gas leak detectors, but most people with normal senses are capable of detecting a gas leak. First and foremost, if you suspect a gas leak is present, do not ignite a match, lighter, or any flame source. Resist from switching electrical switches, or turning lights on or off.

What happens if you light a lighter near a gas leak?

If this leak continues, its concentration may reach a point where a spark – such as that from a cigarette lighter, static electricity, or even the pilot light itself as it is re-lit – will cause a fire or even an explosion.

How strong is gas leak smell?

Natural gas has no smell, which means a small leak would be impossible to detect. A hissing sound is not always present either. That's why your utility company adds mercaptan, a harmless chemical, to the gas. Mercaptan smells like sulphur, or rotten eggs, to help you identify gas leaks.

Man searches for a gas leak with a lighter

What does gas leak smell like?

Natural gas and propane have a distinctive smell for a reason. For safety purposes, utility companies use an additive called mercaptan that gives the colorless and odorless gases a smell that is hard to miss. Most people describe this smell like something like rotten eggs, sewage, or sulfur.

How often do houses explode from gas leaks?

An estimated average of 4,200 home structure fires per year started with the ignition of natural gas. These fires caused an average of 40 deaths per year.

Will a lit cigarette ignite gasoline?

Remember the vapors, not the liquid, ignite. That means a lit cigarette doesn't have to be near the gasoline for it to catch fire. (Editor's note: Studies show lighted cigarettes don't ignite gasoline, because it's a smoldering ash.

Can a gas leak cause an explosion?

An explosion can occur when a gas pipe is leaking. In a confined space like a home or business, the gas will mix with the air, increasing the pressure of the space. When there is a spark or flame (even a static electricity spark might be enough) present, the gas will ignite, causing an explosion.

What should I do if I smell gas?

If you smell gas inside:

1. Keep everyone away from the area of the odor.
2. Don't smoke or strike any matches.
3. Don't light any candles.
4. Don't flip light switches on or off.
5. Don't use a telephone.
6. Don't use any electrical equipment or lights that might create a spark in the area of the odor.
7. Don't use the doorbell.

How long after a gas leak is it safe?

After you've had a leak, authorities typically recommend that you open up your doors and windows and let the home air out. Typically, you'll need to allow your home to air out for fifteen minutes to a few hours, but the exact timeframe depends on the severity of the leak and wind conditions in your area.

Is it normal to smell a little gas near stove?

Keep in mind that, if the smell is faint, this is not necessarily a cause for alarm — it's perfectly normal for a natural gas smell to linger if you're lighting your stove or when the pilot light for one of your appliances goes out.

How does a gas leak make you feel?

Sickness & Fatigue

Exposure to a 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.

How likely is a gas leak to explode?

A natural gas leak can create an explosion if there is an ignition source and the leak is severe enough. While this is fairly rare, gas leaks are incredibly dangerous and should be handled with urgency.

How common are house gas leaks?

Gas leaks are very common in our home. They can be very dangerous due to the increased chances of them causing a fire, explosion or even carbon monoxide poisoning. They can go unnoticed for a long period of time because some of them, such as carbon monoxide is colorless and also odorless.

Can dried gasoline catch fire?

Once the gasoline has dried up, it's been consumed, and assuming the area is well-ventilated, the risk of a vapor ignition is low. That doesn't mean that the risk of a fire is reduced to zero, though, because while dry gasoline isn't flammable, it can still burn.

Are gas fumes heavier or lighter than air?

Gasoline produces ignitable vapors that are 3 to 4 times heavier than air and can travel for great distances along the ground. Gas vapors tend to accumulate in low or enclosed spaces. These vapors can then be ignited by a nearby open flame, such as a pilot light of a water heater.

Can gas fumes ignite from a cigarette?

The consensus in the literature is that cigarettes make poor ignition sources for most ignitable liquids and gases, but that it is possible to ignite a limited set of ignitable liquids and gases with a cigarette.

Can a gas leak cause a house fire?

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.

Can you smell a gas leak?

Since natural gas doesn't actually smell like anything, a chemical called mercaptan is added to help you detect a leak. Mercaptan has a very distinct and unpleasant odor that many people compare to the smell of rotten eggs.

How can I prevent gas explosions in my house?

Install natural gas detectors both in your home and in the workplace. Install gas detectors anywhere gas could possibly accumulate, but also where people will be able to hear the alarm. Maintain and monitor gas detection equipment on a regular basis. Make sure the batteries are working.

Will carbon monoxide detector detect gas leak?

Ultimately, no, a carbon monoxide detector cannot detect a natural gas leak. Carbon monoxide (CO) is a toxic gas created when fuel is burned in the presence of low levels of oxygen. Carbon monoxide is very different from methane and cannot be detected with the same sensor.

Is it OK to breathe natural gas?

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.

Should I open windows if I smell gas?

DO NOT open your windows if you smell natural gas in your home! Natural gas is combustible only when it makes up 5-15% of the air in a given space. By opening a window, you might actually make the area more unsafe. DO NOT turn on/off any lights or appliances if you smell natural gas in your home or building.

What smells like gas but isn't gas?

Sulfur is often the cause of a gas smell in homes without gas leaks. It smells identical to the foul rotten odor of gas leaks, but it's not nearly as harmful in this case. Bacteria found in sewage systems or your kitchen sink release sulfur over time, causing the smell to permeate your home.
