An aerial attack was part of the effort to put out a fire in a wood chip pile at GreenFirst Forest Products in Cochrane this morning. Fire chief Richard Vallée says his department responded shortly after 5:30. An aircraft from local company Expedition Helicopters joined the fight. “They had a helicopter here in Cochrane that had the water bag on it,” says the chief, “so they picked up a couple loads from Commando Lake and the other ones came in from farther south, close to the (Polar Bear) Habitat.” “It was pretty aggressive firefighting,” he adds, speaking from the scene.”There’s a lot of things here that could go on fire, so we did a good job of snuffing it out.” Firefighters will spend the afternoon pulling apart the burned wood chips and dousing hot spots.
