Definition & Operational Usage
Hydrant pressure loss refers to the decrease in water pressure that occurs between the municipal water supply and the fireground, primarily due to friction losses in hoses and fittings, as well as elevation changes. Not to be confused with pump pressure loss, which pertains to reductions occurring within the fire apparatus pump itself. Accurate assessment of hydrant pressure loss is crucial for maintaining effective water delivery during fire suppression operations, particularly within the Incident Command System (ICS) framework.
