What percentage of coverage can a 200' preconnect achieve in a mega structure?

In the context of firefighting operations, particularly within mega structures, the reach and effectiveness of a preconnect hose line is critical. A 200' preconnect typically offers a certain percentage of coverage based on the layout and dimensions of the structure, the type of emergency response, and the firefighting strategy employed.

A 200' preconnect is generally considered to allow for around 25% coverage in a large area like a mega structure. This is due to the physical limitations imposed by the hose length, which restricts the firefighter's ability to maneuver effectively throughout expansive or multi-level spaces. The further the distance needed to stretch the hose, the more limited the coverage becomes.

In larger buildings, factors like floor layout, stairways, and the need for multiple access points significantly influence how much area a single preconnect can effectively serve. Consequently, while it may seem manageable at first, a 200' preconnect can only effectively cover a limited portion of a mega structure, leading to the conclusion that 25% is a realistic and practical assessment of its capabilities in such scenarios.
