What type of hose is generally utilized for attack lines?

The type of hose that is generally utilized for attack lines is typically in the range of 1.5 to 2.5 inches in diameter. This size is optimal for delivering adequate water flow and pressure for effective fire suppression. Attack lines require a balance between maneuverability and water delivery, and hoses within this diameter range provide firefighters with the necessary flexibility to navigate through buildings or around obstacles while also maintaining a sufficient volume of water to combat most structural fires.

While larger hoses, such as 3-inch or 2 to 4-inch options, may be suitable for certain operations, they are primarily used for supply lines rather than direct attack lines. A 1-inch diameter hose is often too small for firefighting applications and does not provide the needed flow rate to effectively suppress a fire. Thus, hose diameters within the 1.5 to 2.5-inch range are the standard for attack lines, ensuring effective firefighting capabilities.
