Answer:
When a fire hose pipe ejects large amount of water in the forward direction at a high velocity, then the forward going stream of water exerts a backward reaction force due to which the hose pipe tends to go backward and slips from the hands of fireman. This backward movement of hose pipe makes it difficult for a Fireman to hold a hose pipe. And the Fireman has to hold the hose pipe strongly.
