My department had been at a structure fire for about four hours by the time of the incident. I was sitting with two other juniors and two senior members. We had just set up the 4 inch hose to pump up towards the structure. We were about a quarter mile away from the fire. One senior member was operating the pump and the other keeping an eye on the pump panels on the side of the apparatus. One junior was standing near the hose and the other farther away on the sidewalk while I was closer to the hydrant. Everything seemed to be going well until I heard this rush of sound and a geyser of water came shooting out of the 4\\” hose. I quickly got farther away from the hose and the pump operator cut the water. I saw one of the juniors lying on the ground near the hose. Both of us juniors that were uninjured ran to his side. We saw that he was bleeding from a cut in his head and immediately yelled for assistance. The pump operator quickly jumped off the truck and came to see. An ambulance was called for both the junior and the other senior member who was bruised from trying to grapple with the hose. The junior ended up with a slight concussion with the cut on his head and a broken growth plate in his leg which was not discovered until they removed his bunkers at the hospital. Both people are both back to the department and running smoothly, albeit with a little more respect for the hose than before.
Remember to never stand too close to the hose, and do NOT try to stop it from moving. It will only injure you, especially if it is a larger size hose.
