A-Total Fire Protection

Standpipes are a vital tool in the prevention of fires in high-rise structures. These systems consist of pipes that connect a water supply to a hose connection. It might be useful to think of these systems as an extension of a fire hydrant system. Many also include a sprinkler element. Standpipe systems are designed specifically to provide fire protection water to hose lines placed in strategic locations throughout a building structure. Let’s take a closer look at the three classifications of standpipe systems.


Standpipe Classifications

Class I

Class I standpipe systems provide a connection for a 2.5-inch hose and are typically meant to be used by trained personnel or by the fire department during a fire emergency. This class of standpipe has no hose attached; as a result, the fire department will need to carry hose packs to the necessary floor to begin operations.

Class II

Class II standpipes provide fire protection hose stations for 1.5-inch hoses. These, too, are meant to be utilized by trained personnel or by the fire department. Typically, these types of standpipes are housed in cabinets and use up to 100 feet of hose.

Class III

Class III standpipe systems provide both 1.5-inch hose stations and 2.15-inch hose connections to supply a larger amount of water if necessary. As with the other two systems, a class III standpipe fire protection system should only be operated by individuals who have been trained to handle heavy fire streams.
