A hose that ejects large quantities of water at high speed has a high momentum. According to newton's law of action-reaction, the water exiting from the hose will provide a force against the hose in the opposite direction. In other words, the hose would recoil. To prevent the hose from recoiling, a firefighter must exert a similar amount of force.
