Class 1 Dry Standpipe

Class 1 Dry Standpipe – What You Must Know!

Do you know about the Standpipe systems? This system has a series of pipes that connects the water supply to hose connections, mainly operating as an add-on of the fire hydrant system. These pipes are designed to provide a pre-piped water system for the building residents or the fire departments. The systems are installed in large structures to aid the firefighters to deploy attack hose lines effectively with appropriate water pressure and volume.

The system may also be designed for first aid fire appliances, heavy stream applications, or have features of both. It is imperative to understand the difference and recognize the designs, as it helps plan the fire attack and save lives and property.

The older structures only have standpipe systems whereas the latest buildings have a combination of both, which comprises of the standpipe system and the fire sprinkler system.  This combination is very common in large floor structures, where most of the facility perhaps be at a distance from the main outside entrance, and in multistory buildings to avoid long lengths of hose in halls and even on the ground.

Standpipe Systems and Its Different Types

Class 1 Dry Standpipe does not have any hose attached. The firefighters generally carry hose packs to the floor level, usually a stairwell, which allows them to start their operations and connect to the available standpipe system. Ensure to hire a professional fire protection service, so that the connections match the hose threads used by the firefighters.
  • Class II Standpipe – This standpipe system provides 1 1/2 inch hose stations to source water to the firefighters during the initial retort. Class II Standpipes are generally available in cabinets with 100’ of hose.
  • Class III Standpipe – This standpipe system comes with 1 1/2 inch hose stations that supply water for use by experts and a 2 1/2 inch hose connection which is useful in supplying a larger volume of water that is typically to be used by the fire departments and those skilled in heavy fire streams. Most of these standpipe connections come with a 2-1/2 inch reducer to a 1-1/2 hose connection.
