Fire Hose 06
Fire Hose 06 : Connections: Hose connections are often made from brass, though hardened aluminum connections are also specified. In countries which use quick-action couplers for attack hoses, forged aluminum has been used for decades because the weight penalty of brass for Storz couplers is higher than for threaded connections. Threaded hose couplings are used in the USA, Canada, and Britain. Each of these countries uses a different kind of threading. Many other countries have standardized on quick-action couplings, which don't have a male and female end, but connect either way. Again, there is no international standard: In Central Europe, the Storz Connector is used by several countries. Belgium and France use the Guillemin connector. Spain, Sweden and Norway each have their own quick coupling. Countries of the former Soviet Union area use the Gost coupling. In the USA, a growing number of departments use Storz couplers for large diameter supply hose, or other quick-action couplings. Because the usage isn't standardized, mutual aid apparatus might have a small compartment dedicated to a multitude of hose adapters. The different styles of hose couplings have influenced fireground tactics. Apparatus in the USA features "preconnects": Hose for a certain task is put into an open compartment, and each attack hose is connected to the pump. Time-consuming multiple connections or problems with male and female ends are avoided by tactics. In countries where Storz (or similar) connectors have been used for attack hoses for generations, firefighters drop a manifold at the border of the danger zone, which is connected to the apparatus by a single supply line. As a result, the tiny item "hose coupler" has also influenced the looks and design of fire apparatus
