Virus or not, we must be ready and able to respond to all who call for help. Tonight's drill was to familiarize members with controlling the hose nozzle while using 2 1/2 " and 2" hoses at various pressures and flow rates and to calculate the GPM flow rates with various nozzles, hose diameters and pump discharge pressures. Advancing a hose into a fire can be difficult because of the nozzle back-pressure as well as the "water weight" in the hose length. A fire hose, under pressure, will present resistance to bend and be extremely difficult to advance up a stairway and around turns. A strong, well-trained team on the advancing hose must work together cohesively as they brave the heat, flame and punishing steam inside a burning structure.
