For vehicle fires, what is the minimum length of hose recommended?

The recommendation of 100 feet of 1 3/4 inch hose for vehicle fires is based on the need for both adequate flow and reach when confronting such incidents. Vehicle fires can sometimes be unpredictable and can spread rapidly, so having a hose of this length allows firefighters to maintain a safe distance while ensuring sufficient coverage of the fire area. The 1 3/4 inch diameter strikes a balance between providing adequate water flow for effective suppression and maintaining manageable handling characteristics, which is crucial in emergency scenarios where speed and efficiency are vital.

In the context of vehicle fires, firefighters must be prepared to position themselves at a safe distance to minimize risk from flames, heat, and potential explosions, hence the importance of hose length. The designated diameter also matches the flow requirements needed to tackle the fire effectively, while still allowing for maneuverability in tight spaces typical of many vehicle incidents.
