1. Distinguish the detailed leakage mode of combustible gas in case of leakage according to the air flow direction and wind direction of the site.
2. Carefully analyze the specific way of the leakage state of the leakage point, and then make different estimates and disposal methods for different comprehensive conditions.
3. According to the density of the leaked gas, detect the flow trend of the air and then develop a three-dimensional flow trend map of the leakage to make a reliable method.
4. Under poor ventilation conditions, if it is in an open flammable gas diffusion environment, the probability of causing the content of flammable gas to close to or exceed the explosive state is also great, and these are all important safety monitoring points.
5. Find out what leakage point the detection device is likely to have, and analyze the severity of leakage according to the leakage direction and pressure of combustible gas.

In order to detect combustible gas, the combustible gas detector needs to promote the communication between the detector and the detection environment, so it is impossible to avoid all kinds of polluting gases and dust in the environment entering the detector, and its damage to the working conditions of the detector is objective. The working environment of the combustible gas detector is relatively bad, and many of them are installed outdoors, Improper maintenance may cause error or failure in detection of combustible gas alarm. Therefore, regular cleaning and maintenance of combustible gas detector is an important work to prevent failure.
