Which type of fire suppression system is most commonly installed to provide automatic suppression in buildings?

• A. Standpipe
• B. Deluge
• C. Sprinkler
• D. Wet chemical

Answer: (C)

Automatic sprinkler systems are the most common way buildings are protected with automatic fire suppression. These systems have pipes filled with water and sprinkler heads that release water automatically when a head is heated to its activation temperature, limiting the spread of a fire without human intervention. This broad approach is widely installed in many building types, providing immediate response to heat and flame. Standpipes are water distribution systems that firefighters use to supply hoses during an active fire; they don’t automatically suppress a fire on their own in the building. Deluge systems are a type of sprinkler system where all heads discharge water when the system is activated, used in high-hazard areas and are less common in typical buildings. Wet chemical systems are specialized for commercial kitchens to tackle cooking fires and aren’t the general building-wide solution.
