Abstract: In this study, ethylene-vinyl acetate copolymer (EVA) shoe material stacking fire model was established because of its high fire risk and difficult to extinguish. The influence of fire extinguishing agent flow rate on the fire extinguishing effect of EVA shoe materials was investigated, and the difference of fire extinguishing efficiency between foam fire extinguishing agent and water-based extinguishing agent was compared. The results show that the flow rate of fire extinguishing agent is the key factor affecting its extinguishing efficiency on Class A fire, and the difference in fire extinguishing and cooling effect of water and AFFF can be effectively distinguished at the flow rate of 0.80 L/min. The fire control performance and cooling effect of high expansion foam and water-based fire extinguishing agent are significantly better than that of AFFF and AFFF/AR. The formation of fire extinguishing foam is conducive to improve the utilization rate of fire extinguishing water. Wetting performance is an important parameter affecting the water-based fire extinguishing agent to EVA shoe material fire fighting.
