The commander informed them of the procedure and first connected the top discharge pipe of the tanker with the flange of the transfer pipe and pressurize the tank. According to the procedure, when the pressure reached the required level, sulfuric acid still did not flow out, so they volunteered to take deflation decompression to open the cover of the notch, check and found that the discharge pipe in the tank was blocked. They also dismantled the flanges and used steel pipes to plug them into the discharge pipe. Unexpectedly, when the discharge pipe was opened, a white foamy liquid up to 3 meters thick was sprayed in the pipe. The three people standing in the tank did not react until the body and face were splashed with sulfuric acid. As the three people did not wear protective masks, the liquid entered the eyes of the three people and was washed by water and sent to the hospital by the freight yard.
