Oxford firefighters responded to the early Wednesday morning after a sprinkler system malfunction caused fire retardant foam to spray throughout a hangar.
The incident occurred about 5 a.m. in a hangar that held two jets, two small fixed-wing aircraft and a couple of automobiles, said Oxford Fire Chief Scott Pelletier. Nobody was injured, he said.
Foam seeped into a storm drain, a retention pond and wetlands near the airport, and workers from the state Department of Energy and Environmental Protection were called in to clean the area, Pelletier said. A DEEP contractor also helped with the cleanup, he said.
An investigation into what caused the malfunction is ongoing by the state fire captain, Pelletier said.
Another similar incident occurred where foam sprayed throughout a hangar due to a malfunction that occurred when the power went out after the autumn nor’easter in late October/early November. Pelletier said it appears at this point the two incidents were not caused by the same malfunction.
