Foam Fire Suppression Systems

Nasa armstrong flight research center recently upgraded the foam fire suppression system for our aircraft support hangar.

Foam fire suppression systems. In this video fire protection expert lee kaiser. The surfactants used must produce foam in concentration of less than 1. When mixed correctly these parts form a homogeneous foam blanket that extinguishes flames by the combined mechanisms of cooling separating the flame source from the product surface suppressing vapors and smothering. National fire protection association nfpa 409 standard on aircraft hangars.

The safety system uses high expansi. The foam bubbles are made by mixing a foam concentrate with water to make a foam solution. The size of the facility the hazard area to be protected the authority having jurisdiction and the assets being protected all play a big role in deciding what fire suppression system to use. These are just some of the issues resulting from false activations of foam fire suppression systems.

Firefighting foam is a foam used for fire suppression its role is to cool the fire and to coat the fuel preventing its contact with oxygen resulting in suppression of the combustion fire fighting foam was invented by the russian engineer and chemist aleksandr loran in 1902. Foam fire suppression systems work by cutting off the fuel source from oxygen and preventing combustion. Fire suppression foam is comprised of three parts. Low expansion foam fire extinguishing systems are applicable to special hazards usually involving flammable or combustible liquids such as storage tanks.

Every facility has different needs when it comes to fire suppression. Foam amplifies the effectiveness of water in fire suppression by breaking the surface tension making the droplets smaller and enhancing cooling of the water. Foam concentrate water and air. High expansion foams those that expand at a rate of 200 1000 times.

Different varieties of foams and chemicals are used for different fire sprinkler applications so the system should be tailored to the exact needs of the facility the. At acaf systems we combine over 20 years of experience providing firefighting and fire suppression systems with a passion for continual innovation and a thorough understanding of the regulatory demands on the industry. Once they are applied to a surface the foam can quickly expand depending on the type of foam fire suppression system being used the foam can expand up to 1000 times. The foam solution is then mechanically agitated to form bubbles.

If foam escapes containment within the hangar environmental contamination can occur and the consequences can be far reaching. Other components of fire retardant foams are.
