The length of time you need to air out your home after a gas leak is determined on the cause. If the reason is as simple as a gas stove left on for an hour, it will just take a few minutes to remove the odor and harmful fumes, and you will be able to return to your home immediately. However, if the source of the leak is a broken pipe in the foundation, it may take more time than that to find and repair it.
If you are unsure about how to respond to a gas leak, call 911 immediately. The gas company will not come out to your home without a call from someone with authority over the property. They will also not shut off your gas unless there is a safety issue involved. If you have children or pets, make sure they are safely away from the site of the leak before you call them.
If there is no one at home to answer the door, leave your name and phone number and a message indicating that you will be there shortly. If there is still no one home after you have left messages, call the gas company back to let them know that you cannot reach the residents. This way they will not shut off your service unnecessarily.
Make sure the entire house is cleared of people and animals before you turn off the gas. If you wait until you get home to turn off the gas, you might not do so until morning when no one is around to hear the switch hit the floor.
If you leave the stove on for several hours though, or if there's no one available to turn off the stove quickly, you may have to find another way to relieve the pressure.
Stove gas is mostly made up of methane and ethane molecules. As these molecules break down they can go into solution in water, forming hydrogen sulfide. The hydrogen sulfide then dissolves in soil, releasing more sulfur dioxide into the atmosphere. SO2 is very reactive and can form other chemicals when it reacts with oxygen in the air. For example, it can combine with water to create sulfuric acid, which can damage wood furniture.
The best way to prevent harm to yourself and your family is to simply turn off your stove when you aren't using it. This will help to reduce the amount of time that it is burning fuel but also reduces the amount of gas that is released into the atmosphere.
If you are unable to turn off your stove easily, you may want to consider installing a safety switch. This will cut off power to the stove if it isn't removed within a certain time period, preventing it from being left on indefinitely.
The time it takes to clean and repair a gas leak in your house is determined by local labor costs. It might take anything from 30 minutes and several hours. The longer the leak, the more likely it is that you will need a professional to find and fix it.
A gas leak can be caused by a number of things including broken pipes, aging appliances, or intentional tampering. If you suspect that there's a gas leak in your home, call your local gas company immediately before doing any further reading on how to stop a gas leak. They will be able to tell you if the problem is with their equipment or not. If it is not their equipment, then you will need to contact a professional to have the leak found and repaired.
Once the gas company has had time to arrive at your location, they will start by making sure everyone in the vicinity is safe and well-informed about the situation. They will also check all electrical equipment and other sources of ignition to make sure that they are not leaking or exposed to fire. After this has been done, the technician will begin looking for signs of the source of the leak. This may include checking floors, walls, and ceilings for damage that could indicate where the main line is located. When the source is found, it will usually be fixed within an hour.
