Study on the Improvement of Fire-Fighting Tactics for the Stable Supply of Fire Extinguishing Water

Abstract

The connected water pipe facility is an important fire extinguishing facility for supplying fire water to firefighters on the fire floor. However, there are cases where fire water is not supplied quickly, which is also caused by the inability to find the connection water pipe inlet owing to unclear regulations on the installation location of the connection water pipe facility fire safety standards. If the connected water pipe facility is not found, fire-fighting tactics involving ropes are used, which takes a lot of time. To improve this problem, we confirmed experimentally that fire extinguishing water can be quickly and stably delivered to fire suppression personnel using a water outlet (40 A) installed in an indoor fire extinguishing tank on the first floor of an apartment. Through the experimental results, the Fire Safety Standards (NFSC 502) for Connected Water Pipeline Facilities (NFSC 502) proposed a plan to improve the fire safety standards (new) that require installation of water outlets (65 A, rotating) in the indoor firebox on the first floor of the apartment. If the revised fire safety standards are applied to the new building, firefighters who arrive at the site can quickly and stably supply fire water through the connecting water pipe connection port (65 A, rotary type) installed in the indoor fire extinguishing tank.
