Deluge AFFF Foam Fire Suppression System is a highly effective fire protection solution designed for rapid response in high-hazard environments. Utilizing Aqueous Film-Forming Foam (AFFF), this system suppresses fires by creating a barrier between fuel and oxygen, cooling the affected area, and preventing re-ignition. These systems are critical in industries where flammable liquids, chemicals, or fuel pose significant fire risks.
What Is a Deluge AFFF Foam Fire Suppression System?
A Deluge system is a type of fixed fire protection system where a network of open nozzles is connected to a water supply via a deluge valve. Upon activation, water mixed with AFFF foam concentrate is instantly discharged over the entire hazard area.
The AFFF foam is an aqueous solution that generates air-filled bubbles, creating a foam blanket that suppresses fire in three main ways:
- Cuts off oxygen supply to the fire
- Cools the fuel to below its ignition point
- Prevents flammable vapor release
How Does AFFF Foam Work?
AFFF (Aqueous Film-Forming Foam) is lighter than most flammable liquids and water, allowing it to spread quickly across burning surfaces. The foam forms a film that seals the fuel surface, blocks oxygen access, and cools the area, extinguishing the flames effectively.
This makes AFFF ideal for Class B fires involving flammable liquids such as gasoline, diesel, jet fuel, and other hydrocarbons.
Key Features of Deluge AFFF Systems
- Instant discharge upon detection of fire
- Wide-area coverage with open spray nozzles
- Mixes foam concentrate with water for effective extinguishing
- Remote or manual activation
- Ideal for high-risk industrial applications
Applications of AFFF Foam Deluge Systems
Deluge AFFF foam systems are widely used in:
- Aircraft hangars
- Petrochemical plants
- Oil and gas refineries
- Fuel storage facilities
- Power plants
- Loading racks and flammable liquid processing areas
These environments demand quick, large-scale foam deployment due to the volatility and high flammability of materials involved.
Benefits of Deluge AFFF Foam Systems
- Rapid fire suppression
- Minimized fire damage and downtime
- Enhanced personnel and property safety
- Efficient use of foam concentrate
- Reduced risk of re-ignition
Compliance and Safety Standards
AFFF foam deluge systems must comply with international safety standards and regulations, such as:
- NFPA 11 – Standard for Low-, Medium-, and High-Expansion Foam
- UL/FM Approved foam concentrates
- Factory Mutual and OSHA guidelines
Conclusion
The Deluge AFFF Foam Fire Suppression System is an essential fire protection method for high-risk industrial environments. Its ability to rapidly deploy and effectively extinguish flammable liquid fires makes it a preferred choice for industries where safety and operational continuity are critical.
