harm
1. When the concentration of combustible gas exceeds the lower limit of explosion, it will explode when it encounters fire (lighter, electrical switch, static electricity, etc.), causing injury.
2. Carbon monoxide is a colorless, odorless and highly toxic gas. It is inhaled through the respiratory tract and combined with human hemoglobin, causing hypoxia and poisoning.
3. City gas itself contains a large amount of carbon monoxide, so when the gas leaks, there is a risk of explosion and carbon monoxide poisoning. In addition, incomplete combustion of gas, kerosene, wood, etc. also produces carbon monoxide.
