When security guards come to your home, they will check the safety of gas facilities in your home for free and put forward reasonable suggestions. They will inform users immediately once they find a security risk. And some fake security inspectors will sell you products such as alarms. Some products not only fail to protect safety, but also may cause safety hazards such as air leakage.
Finally, the security inspector will generally publicize the common sense of safe gas use to you and issue a small manual on safe gas use. Please also read carefully to learn more about gas use and use gas safely.
Coal gas is a combustible gas processed from coal. According to the processing method, gas properties and uses, it can be divided into: water gas, semi-water gas and air gas (or producer gas) obtained from coal gasification.
