Fire extinguishers wholesale to explain commercial kitchen fire prevention

The fire caused by commercial kitchen hearth is a kind of common fire which should be protected against fire. And automatic kitchen fire extinguishing device is a better fire extinguishing device for kitchen hearth. Fire extinguisher manufacturers know that in recent years, kitchen fire has been highly valued by the relevant management departments, the protection of such fire technology will be further studied. It can be expected that with the continuous improvement of China's fire laws and regulations, the problem of kitchen fire protection will be better solved.

The prevention of commercial kitchen fire can be considered from several aspects. Second, strengthen the control and monitoring of fuel, such as fuel selection, pipeline valve leakage detection and closure; Third, strengthen operation and use management, such as regular pipeline cleaning, to prevent excessive oil temperature; The fourth is to install fire fighting facilities. Automatic fire extinguishing system is a positive and effective preventive measure.

At the same time, the commercial kitchen fire does not reach the burning point, cooking oil in the pot will not burn, and once burned has a high enough heat to maintain the characteristics of continuous burning. Even when the flame is extinguished from the surface, the oil in the oil pan remains quite high beyond the point of spontaneous combustion. Uncooled oil can reignite at any time after contact with oxygen. This makes such fires more difficult to extinguish than gasoline, diesel and other oil fires.

In view of the characteristics of kitchen fire, many domestic enterprises have conducted in-depth research on the fire-fighting equipment of commercial kitchen fire, and successfully developed the fire-fighting system for kitchen.
