skum high-expansion (hi-ex) concentrates produce flexible firefighting foams used in fighting both indoor and outdoor class a, class b, and lng fires. expansion ratios from 50:1 up to 1000:1 make these foams suitable for fire suppression in a variety of applications including aircraft hangars, flammable liquid storage areas, and lng facilities. our hi-ex concentrates can quickly form substantial volumes of foam for large-capacity applications in fire and vapour suppression. when used in conjunction with skum high-expansion generators, hotfoam hi-ex concentrate is capable of totally flooding over-sized rooms and enclosures for effective suppression of horizontal and vertical (three-dimensional) fires with minimal water usage. hi-ex foam is often used to suppress fires in large buildings containing high value property such as aircraft hangars and distribution warehouses.
hangar 811 fills with foam during a test of its high expansion foam fire suppression system sept. 11, 2020, at travis air force base, california. (u.s. air force photo by senior airman cameron otte) hangar 811 sits empty prior to a test of its high expansion foam fire suppression system sept. 11, 2020, at travis air force base, california. the system is used to extinguish fires inside aircraft hangars to protect airmen and air force assets. the installation of the new fire suppression system, which is designed to protect u.s. air force assets, was the final renovation in a series of hangar 811 upgrades. the new fire suppression system replaced the hangar’s original aqueous film forming foam system.
“the first steps we took were to fix up floors and replace the lights in the hangar.” “the hangar floor needed to be repaved, sanded and painted white,” said ellestad. ellestad and his airmen had to improvise to get the job done. “we needed to buy portable aircraft scale wash systems and set up a frac tank, basically a container to catch all the soap and grime from the aircraft, to meet environmental standards.” “the old fire suppression needed to be replaced because along with eliminating the fire it would also damage our aircraft,” said staff sgt. “and, like soap it expands; however, this foam is called high expansion foam; it’s able to expand up to 200 percent or more than the liquid it starts as.” for a fire to survive it needs a fuel source, heat, and oxygen. “this is why we use the new foam system because it’s able to smother fires, taking away the oxygen from whatever it’s touching and reduces the heat, while not damaging the aircraft.” “this foam is only dangerous if you get covered by it because one of its core functions is to absorb oxygen,” said ward.
