Study Notes
Standpipe and Hose Systems
- Standpipe and hose systems enable rapid deployment of fire hoses and fire streams at locations away from fire apparatus.
Standpipe System
- Consists of wet or dry pipes in single or multi-story buildings, with fire hose outlets for quick access during firefighting.
Reducer
- An adapter for attaching a smaller hose to a larger one; features larger female threads and smaller male threads.
House Line
- A permanent, private standpipe hose line for use in fire emergencies.
Class I Standpipe Systems
- Intended for trained fire suppression personnel.
- Features 2.5-inch hose connections or hose stations attached to the standpipe riser, may include a reducer.
Class II Standpipe Systems
- Designed primarily for building occupants.
- Provides 1.5-inch hose and nozzle, categorized as single-jacket type.
Class III Standpipe Systems
- Combines elements of Class I and II.
- Supplies 1.5-inch hose stations for trained occupants, with optional removal of hose, nozzles, and rack by local jurisdictions.
Components of Standpipe Systems
- Includes hose stations, water supply, water-flow control valves, risers for water transfer, pressure-regulating devices, and Fire Department Connection (FDC).
NFPA 14
- The standard for the design and installation of standpipes, establishing three classes of standpipe systems.
Automatic Wet System
- Contains water at all times, meets system demand automatically, and maintains pressure; unsuitable for cold environments.
Automatic Dry System
- Holds air under pressure to ensure piping integrity; water enters the system via a dry pipe valve upon hose valve activation.
Semiautomatic Dry System
- Permanent water supply ready to meet demand but requires activation to provide water at hose connections.
Manual Dry System
- Lacks a permanent water supply; water is available only when connected through the Fire Department Connection (FDC).
Manual Wet System
- Also lacks a permanent water supply and must be maintained full of water from a small source, primarily for leak detection.
