FORT DRUM — The discharge of fire-suppressing foam at Wheeler-Sack Army Airfield on Tuesday morning was deemed accidental by post officials.
Lt. Col. Donald A. Korpi, 10th Mountain Division spokesman, said Wednesday afternoon that the Fort Drum Fire Department found foam was released during a reset of the system caused after a manual alarm box was accidentally dislodged.
The error filled a hangar where six Black Hawk helicopters were being housed with an eight-foot-deep layer of foam. No injuries were reported to soldiers at the hangar.
None of the helicopters was damaged, as the foam was removable with tap water.
The system discharge comes as similar incidents have been reported at other military hangars.
The Washington Post said an allegedly intoxicated Marine in Okinawa, Japan set off a system there in May.
Other recent accidental foam incidents include one in January 2014 at Eglin Air Force Base, Fla., that killed a civilian worker, one at an Army National Guard hangar in Tulsa, Okla. in August 2014 and one at Dover Air Force Base in September 2013.
