Question: 1 / 145

Which type of fire protection system uses water to control or extinguish fires?

Gas detection systems

Firewater monitor and hose-reels

Fixed water deluge system

The fixed water deluge system is specifically designed to control or extinguish fires by discharging large amounts of water over a designated area. This type of fire protection system is particularly effective in protecting against rapidly spreading fires and can be used in various industrial settings where high-hazard materials are present.

The deluge system typically consists of open nozzles connected to a water supply that activates when a fire alarm system detects a fire or when manually triggered. The extensive coverage of water ensures that flames are suppressed effectively, creating a protective barrier that inhibits fire spread and may even cool hot surfaces to prevent re-ignition.

Considering the other options, gas detection systems are primarily focused on identifying the presence of flammable or toxic gases rather than extinguishing fires. Firewater monitors and hose-reels also utilize water, but they are more manual systems that need personnel to operate them actively during a fire incident. Ventilation systems serve to manage smoke and heat rather than extinguishing flames directly. The distinction of the fixed water deluge system lies in its automated, broad application of water, making it a crucial component of fire safety strategies in high-risk environments.
