A metal building and three large logging trucks parked inside were reduced to rubble Saturday after a fire at Wellington, P.E.I., bioenergy company. The Wellington Fire Department responded to a call at Atlantic Bioheat at 8 a.m. Desmond Arsenault, a firefighter and communications officer with the department, said firefighters quickly realized they were in for a challenge. “It was evident upon arrival that there would be little chance … of saving anything inside…. It was just one big ball of heat and flames.” The logging trucks had just been filled with diesel in preparation for the work day Monday. One was loaded with wood chips to deliver to customers who use it in their furnaces, Arsenault said. “It just made for a really hot environment with all types of combustibles inside to burn and generate all kinds of heat and toxic smoke, as well.” …Nobody was injured, Arsenault said. The cause is under investigation.
