Hangar fire suppression system activates at Patrick AFB Published Sept. 16, 2015 By 45th Space Wing Public Affairs PATRICK AIR FORCE BASE, Fla. -- At approximately 10 a.m. a 920th Rescue Wing maintenance hangar's fire suppression system activated, immediately filling the hangar with foam. All maintenance personnel were evacuated and no one was injured. During the activation, two HH-60G Pave Hawk helicopters were inside and it is unknown at this time if they sustained any damage as a result of the foam. The high expansion foam, is a detergent based product, much like dishwashing liquid, and is 97 percent water and 3 percent fire suppression material once fully activated, according to base environmental officials. Although there are no impacts to human health, people with skin sensitivities who come in contact with the foam should simply rinse the material off using warm water. Additionally, there are also no environmental and ecological impacts due to the low concentrations of the foam having dispersed over a widespread area. Rain and sun will naturally break the material down over time. The exact cause of the incident is currently under investigation and any damage to government property/equipment is also being further assessed.
