Foam deluge systems are commonly used in areas where water suppression alone may not be effective or safe, such as around transformers, oil tanks, or areas with flammable liquids. These systems utilize a mixture of water and foam concentrate, which, when discharged, creates a foam blanket over the fire, smothering it and suppressing the flames. Similar to other fire suppression systems, the foam deluge system is equipped with detectors or sensors that monitor for signs of fire. Once a fire is detected, the system activates. Foam deluge systems are effective in extinguishing fires involving flammable liquids or in areas where water alone may not be sufficient. Cleaning up the foam residue after a fire event can be time-consuming and may require specialized equipment and materials. However, the effectiveness of foam deluge systems in preventing catastrophic fires often outweighs the inconvenience of cleanup.
