How many classes of standpipe systems are there? Describe
- 3
- Class 1- provide 2' 1/2" hose connections for fullscale firefighting
- Class 2- Provide 1' 1/2" hose connections for first aid FF. Intended use is fire brigades and occupants
- Class 3-Combination of 1 and 2
-
Types of standpipe systems (5)
- Automatic wet-filled with water at all times and will have an automatically available supply capable of suplying the water demand necessary for firefighting
- automatic dry- filled with pressurized air. thru the use of a valve water admitted automatically when opened. preconnected water supply capable of supplying the water demand
- semi-automatic dry- filled with air that may or may not be pressurized. arranged with devices to admit water into system piping when a remote actuation device located at a hose station, such as a pull station, is activated. Preconnected water supply capable of water demand
- manual dry- normally filled with air; do not have preconnected water supply. FDC must be used
- manual wet- normally filled with water for the purpose of find ing leaks. water supply generally domestic supply. An FDC must be used for firefighting
-
