On Tuesday November 13, 2018 at 0745 hours, Battalion Two was dispatched to 1000 Delsea Drive, the I-295 Industrial Park, for a Commercial Vehicle Fire. Battalion 9201 (Thomas) arrived on location to find a 25′ commercial foam insulation spraying trailer well involved in fire. Squad 921 and the duty Engine, 931, arrived and the crew led off with an 1 3/4 hand line to start suppression. The rear of the trailer had the “hockey puck” type pad locks on it and the crew use the front pumper Hurst Tool from Squad 921 to force open the door. The contents of the trailer started to react with the water being used and the foam line was deployed from Squad 921. A dry powder fire extinguisher was used to knock down the fire that was reacting to the hand line. Crews remained on location to assist the Deptford Fire Department Fire Investigators with their investigation. The Gloucester County Haz Mat Assessment Team was summoned to the scene as the run off from the trailer became a concern.
