The standpipe and hose system refers to a sequential arrangement of piping, valves, hose connection, and related equipment fitted in a constructed structure. There are six developed types of standpipes systems. These types include automatic wet systems, and this system contains water in its pipes sufficient to aid in manual firefighting operations (Kim et al 103146). The automated dry system has pressure in its pipes instead of water. Water is kept out until a hose valve opens, dropping the air pressure in the piping.
The semiautomatic standpipe is made of either pressure or atmospheric air. The role of the pressurized is only supervisory and not allowing water inflow. The manual wet standpipe always has water supplied from the structure’s local water system and not from an established fire service line (Kim et al 103146). Manual dry standpoint contains atmospheric air without any water source. For it to work, the firefighters connect a water source first. The combined standpipe and sprinkle system is structured to enable the use of both the standpipe and sprinkle system supply pipe.
The standpipes systems are broadly classified into three classes, class 1, class 2, and class 3. Class 1 standpipe systems are used by fire brigade professionals skilled in managing complex fire systems (Shuster et al 12). Class 2 systems are equipped for residential use by the occupants and fire brigade. Class 2 systems are primarily placed in the open hallways and corridors. Class 3 standpipe systems are made in a manner that meets the class 1 and class 2 standards.
The equipment can be used by the firefighter serve personnel, the fire brigade, or any other trained person. The three most crucial aspects of consideration in installing the standpipe systems are the height of the building’s rise either above or below the fire department access (Shuster et al 11). Also, the use and occupancy of the structure matter and the presence or absence of the fire sprinkler system determine the required installation.
