[0002] Methane is an important fuel widely used in industry, households and transportation. In industry, methane is used as fuel to process chemicals, produce electricity and generate electricity. Its combustion generates high heat and emits relatively little carbon dioxide and other harmful gases, so it is considered a relatively clean fuel. Methane gas is usually used in suspended pipelines, external force pipes of high-rise buildings and long-distance transmission pipelines.

[0003] Methane is a flammable and explosive gas. When the methane concentration in the air reaches a certain range and encounters a fire source or high temperature, fire or explosion is likely to occur, causing serious harm to the human body.
