What is the minimum length of 1.5, 1.75, or 2 inch fire attack hose according to NFPA 1901?

The minimum length of 1.5, 1.75, or 2 inch fire attack hose according to NFPA 1901 is 400 feet. This standard is designed to ensure that fire departments have an adequate supply of hose to effectively respond to various fire scenarios. A 400-foot length allows firefighters to effectively reach most structures and cover necessary distances on the fire scene.

Having sufficient length is critical for optimizing attack strategies and ensuring efficient water delivery to manage fires effectively. Shorter lengths would potentially limit the operational range and effectiveness of fire suppression efforts, particularly in larger commercial or residential incidents where distances can be considerable. Therefore, the stipulation of 400 feet aligns with best practices in firefighting protocols to provide sufficient reach and flexibility in emergency situations.
