As a kind of combustible gas, natural gas can burn together with air to release a large amount of heat under normal conditions. The normal natural gas combustion process is relatively stable and controllable. However, if natural gas leaks in a space with no air circulation, it will accumulate in the room. When the concentration of natural gas exceeds 5%, once it encounters an open flame or electric spark, natural gas will immediately burn uncontrollably and violently. , And the volume expansion causes an explosion.
Natural gas itself is colorless and odorless. In order to make people detect the leakage of natural gas, the natural gas used by residents is added with hydrogen sulfide or odorous chemicals containing sulfhydryl groups. If the natural gas leaks, we will smell like rotten eggs.
If we are far away from the natural gas source, or in a sleep state, we may not smell the natural gas. To be safe, a natural gas alarm or combustible gas alarm can be installed in the kitchen.
The leakage of natural gas generally occurs at the interface, and the condition of the burning appliances in the home should be checked regularly. Old gas appliances should be replaced in time to prevent aging of pipelines and connections, and gas companies also regularly inspect natural gas pipelines.
