Methane is all round your home. From the gas you use to heat your stove or water to the gas inside your sewer drain, methane has multiple avenues into your home. Unfortunately, uncontrolled methane is explosive and deadly. You can measure for methane gas in many ways, from daily monitoring to emergency inspecting.
Install a multi-gas detector in your basement. A multi-gas detector looks similar to a fire detector, but it measures gas levels in your home. Place the detector by your gas furnace; this is the most likely source of a methane gas leak. You can also place one in your kitchen, another location where you can experience a gas leak. This type of detector works 24 hours a day, 7 days a week and is the best solution for the average homeowner.
Contact your gas company if you suspect a small leak. The gas company has specialised detectors that can read levels and locate where the gas is coming from. This is also a good idea if you suspect a gas leak outside your home where normal detectors will not work. If you feel the gas leak is an emergency, contact your local fire brigade to measure for a leak.
Measure for methane using a methane laser gun, which allows you to measure for methane from a distance of 500 feet. This tool is used by professionals when a leak has been detected but not located. The laser gun allows you to pinpoint a leaking pipe in a tight area that you can't safely access.
