What is the typical size range of supply hoses used in firefighting?

The typical size range of supply hoses used in firefighting is generally between 2.5 to 6 inches in diameter. This size range is designed to accommodate the high volumes of water needed to effectively manage large fires and ensure that adequate pressure is maintained throughout the firefighting operation. The larger diameter hoses are critical for supplying water from hydrants or other sources to fire engines or at the scene of the fire, where significant water flow is imperative for successful fire suppression.

Understanding the range of hose sizes is important for firefighters in order to select the appropriate hose for different situations. Using hoses that are within this diameter range maximizes water delivery efficiency and minimizes friction loss, which is crucial during firefighting operations.
