Foam Fire Suppression Systems

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 fire suppression systems.

We have developed fluorine free foam pressure fire safety systems ready for today s business and manufacturing challenges. Nasa armstrong flight research center recently upgraded the foam fire suppression system for our aircraft support hangar. Other components of fire retardant foams are. Foam and chemical fire suppression systems are used to cool the fire and coat the fuel that the fire is consuming to prevent contact with oxygen and reduce combustion ability.

These are just some of the issues resulting from false activations of foam fire suppression systems. Fire suppression foam is comprised of three parts. Foam suppression systems can be messy and require special strategies and considerations for clean up that other systems do not need. 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.

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. The surfactants used must produce foam in concentration of less than 1. In this video fire protection expert lee kaiser. If foam escapes containment within the hangar environmental contamination can occur and the consequences can be far reaching.

The safety system uses high expansi. 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. Foam fire suppression systems work by cutting off the fuel source from oxygen and preventing combustion. 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.

High expansion foams those that expand at a rate of 200 1000 times. The foam bubbles are made by mixing a foam concentrate with water to make a foam solution. National fire protection association nfpa 409 standard on aircraft hangars. 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.

Every facility has different needs when it comes to fire suppression. The foam solution is then mechanically agitated to form bubbles.
