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 (or equivalent number where you are) 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.

Health Risks

Leaving a gas stove on, whether with or without a flame, can pose serious health risks. Knowledge of the potential dangers and taking immediate action can protect yourself and your loved ones.

Carbon Monoxide Poisoning

When you leave a gas stove on with a flame, it can lead to the production of carbon monoxide. This colorless, odorless gas is a silent killer, as it can quickly build up in enclosed spaces without being detected. Breathing in high levels of carbon monoxide can cause symptoms like:

  • Headaches
  • Dizziness
  • Nausea
  • Fatigue
  • Confusion
  • Chest pain
  • Shortness of breath

If left untreated, carbon monoxide poisoning can lead to loss of consciousness, brain damage, and even death. That’s why it’s essential to have working carbon monoxide detectors in your home and to evacuate immediately if you suspect a gas leak.

Natural Gas Exposure

On the other hand, leaving a gas stove on without a flame means that natural gas is slowly leaking into your home. While natural gas itself isn’t toxic, it can cause symptoms similar to carbon monoxide poisoning when inhaled in large amounts. These symptoms may include:

  • Headaches
  • Dizziness
  • Fatigue
  • Nausea
  • Irregular breathing

Prolonged exposure to natural gas can also lead to more severe health issues, such as memory problems, loss of concentration, and even suffocation in extreme cases.

Long-Term Health Effects

Even if you don’t experience immediate symptoms, long-term exposure to low levels of natural gas or carbon monoxide can take a toll on your health. Chronic exposure has been linked to an increased risk of:

  • Respiratory issues
  • Cardiovascular disease
  • Neurological problems
  • Developmental issues in children
  • Pregnancy complications

To minimize these risks, it’s crucial to have your gas appliances inspected and maintained regularly by a professional. This will help identify any potential leaks or malfunctions before they become a serious threat to your health.

Remember, if you ever suspect a gas leak or experience symptoms of gas exposure, don’t hesitate to evacuate your home and seek medical attention. Your safety and well-being should always be the top priority.

Responding to Gas Exposure

Here’s what you should do:

Seek Fresh Air Immediately

The first and most important step is to get to a location with fresh air as quickly as possible. If you’re indoors, go outside immediately. If you’re already outdoors, move to an area upwind from the gas source. Inhaling fresh air will help dilute the gas in your system and reduce the risk of further exposure.

Call for Emergency Medical Services

Once you’re in a safe location, call 911 or your local emergency medical services. Even if you feel fine, it’s essential to get checked out by a medical professional. Gas exposure can cause serious health issues that may not be immediately apparent, so it’s better to err on the side of caution.

When you call for help, provide as much information as possible, including:

  • The location of the gas exposure
  • The type of gas (if known)
  • The duration of exposure
  • Any symptoms you or others are experiencing

Administer First Aid

While waiting for medical help to arrive, there are some first aid measures you can take:

  • If someone is unconscious, check for breathing and pulse. If absent, begin CPR if you’re trained to do so.
  • If someone is having difficulty breathing, help them into a comfortable position and loosen any tight clothing.
  • If someone is experiencing nausea or vomiting, help them lie on their side to prevent choking.
  • Keep the affected person warm and calm until help arrives.

It’s important to note that administering first aid should never delay calling for emergency medical services.

Follow Up with Your Doctor

Even if you receive medical attention at the scene, it’s a good idea to follow up with your regular doctor. They can assess your overall health, monitor for any delayed symptoms, and provide guidance on any necessary follow-up care.

In the days following gas exposure, watch for symptoms such as:

  • Headaches
  • Dizziness
  • Nausea
  • Fatigue
  • Shortness of breath
  • Chest pain

If you experience any of these symptoms, seek medical attention promptly.

  • Clean the top of the stove after each use once the burners have cooled (small food particles can catch on fire).
  • At least once a week, wash the grates and each burner cap of your gas stove by immersing them in warm, soapy water. Clear out any debris from the burner’s openings using a toothpick.
  • NEVER put water on a fire in a gas stove. Put a lid on the pot and turn off the burner if there is only a small fire in the pot. If the fire is larger, you can put it out using a fire extinguisher, a fire suppression blanket, a wet cloth, or a ton of salt or baking soda.
  • If you smell natural gas but did not leave the stove on, get out of the house right away. Use your mobile device to call 911 or your neighborhood gas company from a safe distance outdoors and outside in the fresh air to report the event.
  • Read the safety instructions that come with your natural gas appliance. You can get in touch with the manufacturer or look it up online if you don’t have the printed handbook.

When to Call Professionals

Contacting the Fire Department

If you suspect a gas leak or have been exposed to high levels of carbon monoxide, don’t hesitate to call 911 (or your country’s equivalent) and request the fire department. They are trained to handle gas emergencies and can quickly assess the situation, evacuate the area if necessary, and mitigate the risk of fire or explosion.

Involving the Gas Company

Once you’re in a safe location, contact your local gas company to report the incident. They can send out a technician to investigate the leak, shut off the gas supply if needed, and make any necessary repairs.

When Professional Help is a Must

While some minor gas stove issues might be resolved without professional intervention, there are several situations where calling for expert assistance is non-negotiable:

  • If you smell gas and can’t locate the source
  • If you hear a hissing sound near a gas line or appliance
  • If you see visible damage to gas pipes or connections
  • If you experience symptoms of gas exposure, such as headaches or breathing difficulties

Preventive Gadgets

There are numerous gadgets designed to help prevent gas accidents in your kitchen. These can provide an extra layer of protection.

Gas Detectors: Your Nose’s Best Friend

One of the most essential preventive gadgets for any gas stove owner is a gas detector. These smart little devices are designed to sniff out even the slightest hint of a gas leak, alerting you with a loud alarm before the situation becomes dangerous. Gas detectors come in various shapes and sizes, from portable units you can place near your stove to hardwired systems that monitor your entire kitchen 24/7.

When shopping for a gas detector, look for models with high sensitivity levels and quick response times. Some advanced units even come with additional features like automatic ventilation activation or emergency shut-off capabilities. By investing in a reliable gas detector, you’re giving your nose a high-tech sidekick in the fight against gas leaks.

Automatic Shut-Off Systems: The Ultimate Fail-Safe

While gas detectors are great for alerting you to potential leaks, automatic shut-off systems take things a step further by actually cutting off the gas supply when a leak is detected. These smart systems typically consist of a valve installed on your gas line and a sensor that constantly monitors for any irregularities.

If the sensor detects a gas leak or an unusually high concentration of gas in the air, it sends a signal to the valve, which immediately shuts off the gas flow to your stove. This fail-safe mechanism can prevent a small leak from turning into a catastrophic event, even if you’re not home to hear the gas detector’s alarm.

Some automatic shut-off systems can even be integrated with your smart home setup, allowing you to monitor your kitchen’s gas status from your phone or receive alerts if the system is triggered. With this level of protection, you can cook with confidence knowing that your stove has its own guardian angel watching over it.

Smart Stove Knobs: Cooking with a Touch of Tech

Have you ever wished your stove knobs could tell you if you’ve accidentally left the gas on? Well, wish no more! Smart stove knobs are here to revolutionize the way we interact with our gas stoves. These high-tech knobs come equipped with sensors that can detect when the gas is flowing, even if the flame hasn’t been lit.

If you forget to turn off the gas after cooking, smart stove knobs will alert you with a notification on your phone or a blinking light on the knob itself. Some models even allow you to set a timer, so the gas automatically shuts off after a certain period of inactivity. With smart stove knobs, you’ll never have to worry about accidentally leaving the gas on again.

Always Play it Safe!

Whether you’re cooking or baking, responsibility is key. If you discover you have left your gas stove on, follow the steps above immediately. It’s important to understand the risks of leaving a gas stove on with and without a flame. One leads to a silent death due to hazardous health, the other leads to a catastrophic explosion. Let’s stay safe!!
