Col. Brian McDaniel, 92nd Air Refueling Wing commander, initiates the foam suppression system test in hangar one Oct. 1, 2015, at Fairchild Air Force Base, Wash. The foam suppression system is capable of producing 238,000 cubic feet of foam concentrate per minute. In the test, the system ran for approximately two-and-half-minutes, and produced over six feet of foam which covered the 68,000 square foot floor of hangar one.

The test ran for approximately two-and-a-half minutes creating over six feet of foam which covered the entire hangar floor, which is 68,000 square feet.

The foam suppression system test conducted by the 92nd Civil Engineer Squadron in hangar one met the necessary requirements Oct. 1, 2015, at Fairchild Air Force Base, Wash. The Ansul High Expansion Concentrate used in the test is very similar to dish soap, resulting in an easy clean-up. The foam was allowed to settle over the weekend which resulted in puddles and very little foam solution. In compliance with environmental regulations, the remaining foam solution is collected and transported to an approved off-site disposal facility.

The foam is known as Ansul High Expansion Concentrate, when mixed with water the solution becomes 2 percent foam and 98 percent water. The system has a capacity to fill one entire hangar with approximately 20 feet of foam. (U.S. Air Force photo/Airman 1st Class Mackenzie Richardson)
