[0002] Aqueous film-forming foam fire extinguishing liquid can foam in aqueous solution. Its aqueous solution is lighter than water, so it can float on the surface of the burning liquid, so it is called "light water foam fire extinguishing agent". Its fire extinguishing principle, in addition to the function of general foam fire extinguishing agents, is that when it disperses on the surface of the burning liquid, it precipitates liquid to cool the surface of the burning liquid, and forms a layer of water film on the surface of the burning liquid, which together with the foam layer seals the surface of the burning liquid and isolates the air. Aqueous film-forming foam liquid is widely used in firefighting.

[0003] In existing tunnel fire-fighting facilities, tanks are usually used to directly store aqueous film-forming foam liquid, so that the aqueous film-forming foam liquid in the tank can be used in emergency situations to meet fire safety requirements.
