Abstract: With the wide use of ethanol gasoline, in order to effectively deal with this particular liquid fire, a new type of highly efficient non PFOS foam extinguishing agent has been developed through the study of key components screening and blending. The product has passed the national standard GB 15308- 2006 foam extinguishing agent detection, the highest level of fire extinguishing performance has been achieved, and the fire extinguishing performance of the product is better than that of other domestic products through comparative tests. Further study is made on the key parameter of extinguishing supply intensity.

Key words: vehicle ethanol gasoline, foam extinguishing agent, supply intensity, fire extinguishing performance
