Article: Both before and after you attempt to fix a gas leak, you need to make sure that the area is well-ventilated. If the area is not well-ventilated, you may have a potentially dangerous accumulation of gas. Open windows and doors. Allow an area to air out before re-entering it or turning on any appliances. If you have any doubt that you've fixed the gas leak, you should not engage in any activity that could result in a gas explosion. This is important, as any fire or electronic activity could potentially ignite accumulated gas. Refrain from: Lighting matches or lighters. Operating electrical switches. Using telephones. Answering your cell phone or using other portable electronic devices. The second you suspect there is an ongoing gas leak, you should vacate the building at once. This is important, as gas leaks can quickly turn into gas explosions. In addition, you might also be overcome by the gas and lose consciousness. After exiting the building, stay at least 100 feet away. If safe, and if you know where it is, locate the gas shut off valve and turn off the gas for the premises. After exiting the building, you should call a professional to properly fix the gas leak. A professional will be able to quickly locate the source of the leak, fix it, and prevent harm to property or people. Call your gas company if you suspect the leak in your home or business is linked to a larger leak in their system. Inform the professional of any steps you've taken to fix the gas leak. If you've turned the main gas switch off, shut off gas to an appliance, added piping, or changed any substantial part of your gas system, they need to know. If you have an uncontrolled gas leak in your home or business, call local authorities immediately. For example, call 911 in the United States.
