True or false: Anytime hose line X is 850 feet, personnel must have additional pump use to relay the water.

The statement is false because the need for additional pump use to relay water does not solely depend on the length of the hose line. While the length of 850 feet can present challenges in maintaining adequate pressure and volume, many modern fire pumps are capable of delivering sufficient pressure over that distance without requiring a relay operation. The capability also varies based on the type of hose, the nozzle being used, the pump's specifications, and the water source's characteristics.

Firefighting tactics often involve assessing factors such as the elevation, friction loss across the hose, and overall pump capacity to determine if additional pumping systems are indeed needed. Standard operational procedures typically guide how to handle long hose lays, and trained personnel will evaluate these considerations rather than assuming additional pumps are mandatory solely based on length. Therefore, the blanket statement regarding the need for an additional pump is not accurate, making it false.
