Leaving the gas stove on with a flame will release carbon monoxide into your home which can be hazardous to your health. While leaving the gas stove on without a flame can fill your home with natural gas which is extremely flammable and may pose the risk of a catastrophic explosion.

It’s important to know how to distinguish between these two scenarios and what steps to take in each. In this article, we give you advice and steps to follow if you have left your gas stove on, with or without the flame.

What to Do If You Leave the Gas Stove On With Flame

Is it okay for your gas stove to be left on for 1 hour? The answer is always no, no, no!

You should ideally never step away from your gas cooking while cooking. Always make sure to turn off the gas stove when you have finished. Leaving your gas stove on can be very dangerous for your health and can even cause explosions. These effects can happen quickly and no matter how much time it has been, it is still not safe.

If the cooker is lit – and it’s left on for an extended period of time – it will produce “carbon monoxide” as the gasses the burnt methane turns into include carbon monoxide – which is fine if vented, but if in an enclosed space, this will remove oxygen from the air and can be dangerous to your health.

Carbon monoxide when inhaled in large amounts can cause carbon monoxide poisoning. You can be breathing in excess amounts of carbon monoxide and be unaware you’re doing so as carbon monoxide doesn’t necessarily smell.

If you have kept the stove on but there is no particular strong gas scent, don’t be fooled! Even if your gas stove is left on without a flame for 2 hours or your gas stove was left on low for 3 hours, this is still very dangerous to your health.

Here are some steps to follow on what to do if you have left your gas stove on with the flame:

  • Immediately turn off the stove or burner to prevent the problem from continuing.
  • Turn on the cooker’s fan to the highest setting possible to help air the room.
  • Make sure to evacuate everyone in the property including pets.
  • Open all windows and doors to air the property. Make sure to take breathers in the fresh air so you do not inhale too much carbon monoxide.
  • At no point should you light anything inside the property if you think a lot of carbon monoxide is present as this can cause a fire.
  • Do not turn on any appliances or activate anything electrical.

What to Do If You Leave the Gas Stove On Without Flame

This is the real danger. If you leave your gas stove on without the flame, then the stove is slowly releasing methane into your home which can result in a catastrophic event!!

If you detect gas, which has a rotten egg-like smell, you might be in trouble. Gas companies add an odorant that smells like rotten eggs to natural gas and propane since they are odorless as a safety precaution. It’s obvious that gas is escaping into the air if you notice that aroma. The stove should be turned off, and you, your family, and any pets should leave right away.

Call 911 immediately. If your stove has electrical or sparks ignition because many ranges can spark when the knob is turned to the “OFF” position, which might result in an explosion. If the meter is outside the house, shut off the gas supply to the house at the meter. The local fire brigade is skilled at locating and isolating gas meters.

Regardless of whether your gas stove uses natural gas (composed of 70-90% methane) or propane gas (liquefied petroleum gas LPG), you need to be extremely careful as both are very flammable. They are equally explosive mixtures with air at room temperature in enclosed spaces.

It’s important to understand these two different varieties of stove gas dissipate differently:

  • Propane gas dissipates in about 2 hours
  • Natural gas dissipates in about 1 hour

The safety advice is to never turn on any electric devices or start a flame (e.g., light a candle or cigarette) if you are in a home where there may be a gas leak because it takes an hour or two for the gas to dissipate. An electric spark occurs during switching electrical appliances, and this can ignite the explosive gas present in the air. As long as first responders have not cleared the house, you should leave.

Although you might think you should open the windows to air out your house, resist the urge to do so. Keep the windows closed! Natural gas can ignite once it accounts for between 5 and 15% of the air in a space. Opening a window can actually increase the danger in your kitchen, which already exists due to the gas there.

Although this is very unlikely, as gas autoignition requires temperatures of around 450 to 500 degrees to occur, which will start a spontaneous fire, it is important to be aware of this. Leave it to the experts!

A gas leak in a closed space means that all of your furniture will presently be relocated to all corners of the neighborhood should you even turn on a light switch. Not only that but opening windows would delay your exit and cause toxic fumes to spread beyond your home.

Here are some steps to follow on what to do if you have left your gas stove on without the flame:

  • You should immediately gather your family and any pets and leave the house, then call 911.
  • Call 911 once you are in a secure location (a neighbor’s house or at the very least on the other side of the street). When emergency personnel comes, they will inspect your gas line and your residence.
  • Do not turn on or off any type of electric device (i.e. lights, ), or gas items (i.e fireplace).
  • Do not open or close the windows.
  • You shouldn’t even start the automobile in your driveway or garage.
