Unit 11: Standpipe Systems

  • FESHE Identify different types and components of standpipe systems

 

Standpipe systems consist of a fixed piping system and hose valve connections to preclude the need for long hose lays within tall or large buildings. Water is fed into these systems either through an automatic water supply or manually through a fire department connection. The system delivers water to hose connections throughout the building, usually in enclosed or exterior stairs (Figure 4.1). Firefighters then extend hose lines from these hose connections to conduct interior fire suppression operations. Standpipes are, in effect, a critical component in the supply of water to interior firefighting crews. Deficiencies can have disastrous consequences, such the loss of three firefighters in the 1991 Meridian Plaza fire in Philadelphia.

The FDC inlet is to the right of the building entrance, the riser pipe extends through the left side stair landings, and hose connections are at each level, including the roof.(Fig. 4.1) A dry standpipe in an exterior stair.
