because of newtons 3 law of motion (to every action there is equal and opposite reaction) the force of water will give impact equal in return and fireman can leave the hose pipe.just like recoil of gun

Hello
The pressure exerted from the hose would be more than enough to knock the fireman holding it backwards, so the fireman braces himself for that force so that he can remain upright to continue fighting the fire.
