Natural gas is one of the safer gases. It does not contain carbon monoxide and is lighter than air. Once leaking, it will immediately spread upward and is not easy to accumulate and form explosive gas.

The use of natural gas as a source of energy can reduce the use of coal and oil, thus greatly improving environmental pollution; As a clean energy source, natural gas can reduce emissions of sulfur dioxide and dust, carbon dioxide and nitrogen oxides by 60% and 50%, and help reduce the formation of acid rain, relieve the earth's greenhouse effect, and fundamentally improve environmental quality.

The increasing demand for natural gas and biogas requires higher reliability and safety as operators of supply natural gas pipe networks. Natural gas has become even more important to industry thanks to the invention of new gas-steam plants.
