Our WSFP San Antonio Branch recently completed a foam test for an aircraft hangar in San Antonio Texas. Watch to see what happens during the test. See how quickly these systems work to protect lives and property.
Effectively, the foam completely smothers the fire, while its high water content provides effective cooling to reduce the fire's heat energy. Well-formulated foam, correctly applied, displays a number of important firefighting characteristics that ensure a fire is extinguished efficiently and securely to prevent re-ignition. These include: stability; cohesion; rapid fire-knockdown; heat resistance; and vapour suppression.
Because of the agent's low density, the foam readily floats on a fire's fuel surface or, in what are called "total volume filling" applications, completely fills the enclosed protected area to extinguish the fire by separating the fuel from the oxygen that is essential for combustion to continue.
The foam simply washes away with water for clean-up.
