DANGERS OF INFLAMMABLE GASES LEAKING
Some of the inflammable Gases are not toxic. But they are extremely flammable and will cause an explosion; it will also kill you by asphyxiation if it leaks into an enclosed space and deprives you of oxygen. In case of methane it only becomes poisonous when it forms part of another gas and is subject to certain circumstances. The bad news is that this happens quite often.
Don’t worry…. Here is a solution for detecting the inflammable gas leakage. The circuit uses a gas sensor which can detect the presence of LPG, Propane, Methane and Hydrogen also other combustible streams.
