Definition & Operational Usage
A booster tank is a water storage container mounted on a fire apparatus designed to supply an immediate water source for initial fire attack without relying on external hydrants. Typically smaller than main water tanks, booster tanks enable rapid deployment of hose lines during the critical early stages of firefighting operations. Not to be confused with a pumper apparatus water tank, booster tanks provide a quick water reserve that supports strategies like the Incident Command System (ICS) and rapid intervention team (RIT) deployment.
