Foam fire suppression systems are specifically designed to tackle flammable liquid fires by creating a smothering blanket that separates the fuel from oxygen. The foam’s water content also provides a cooling effect, preventing re-ignition.
Types of Systems:
- Low Expansion Foam: Creates a heavy, dense foam that is effective for suppressing fires in fuel storage tanks, loading bays, and aircraft hangars. It has a long throw range, allowing firefighters to apply the foam from a safe distance.
- High Expansion Foam: Generates a vast volume of lightweight, fluffy foam that can fill large enclosed spaces like warehouses or marine engine rooms. It is ideal for total flooding of large volumes and provides a three-dimensional solution for complex hazards.
Key Features & Benefits:
- Effective on Class A & B Fires: Ideal for both flammable liquids and solid combustibles.
- Vapor Suppression: The foam blanket prevents flammable vapors from escaping, reducing the risk of explosion.
- Excellent Cooling: The water content helps to lower the temperature of the fuel, preventing re-ignition.
- Versatile: Can be applied through fixed systems, monitors, or hose reels.
