What is the standard nozzle pressure in pounds for solid stream nozzles on hand lines?

The standard nozzle pressure for solid stream nozzles on hand lines typically falls within the range of 50 to 80 pounds per square inch (psi). This range is established to ensure effective water delivery and coverage without causing excessive recoil or compromising the firefighter's ability to control the stream. Operating within this pressure range allows firefighters to maintain an optimal balance, ensuring both the efficiency of the nozzle's effectiveness in suppressing fires and the safety of the operator.

While options outside this range may seem plausible, they either exceed the typical operating parameters or fall short of what's recommended for effective firefighting operations. Maintaining the proper nozzle pressure is critical for achieving the desired reach and volume of water, which ultimately contributes to successful fire suppression efforts.
