On August 28, 2024 at 05:17 the Winchendon Dispatch Center received a 911 call reporting a multi-car accident in the area of 560 Spring Street. Upon arrival of initial units a two vehicle accident was discovered between a SUV and a CNG (Compressed Natural Gas) powered Amazon delivery truck. With the initial ambulance crew checking the occupants of both vehicles it was determined that only the SUV driver required transport to Heywood Hospital with minor injuries. The Driver and passenger of the Amazon truck were uninjured.
During the accident the CNG tank on the delivery truck became detached except for the pressure lines and was sitting next to the vehicle in the roadway. Winchendon Fire crews immediately requested that Dispatch contact the District 6 HazMat Team through Fitchburg Mid-State Control. A perimeter was set up by crews and Winchendon Police and DPW set up a detour around the accident scene.
Upon arrival of a Tier 1 response through District 6 HazMat it was determined to upgrade the incident to a Tier 2 response bringing in other units from District 4 HazMat as well as additional units from the Department of Fire Services, including Massachusetts State Fire Marshal Jon Davine to the scene. Winchendon Crews worked with District 6 HazMat Team Leader Chief Joseph Guarnera to locate an Emergency Response Crew in the state familiar with the situation at hand. Contact was made with Xpress Natural Gas (XNG) out of Andover,MA who sent a technical expert out of Stratham, NH.
While response units were responding from various corners of the state the MA State Police deployed their robot as well as their drone and a drone from the Department of Fire Services to take photos of the tank connections in advance of the technician’s arrival. Once on scene, XNG assisted in determining that the pressure lines could be methodically removed allowing the tank to be loaded on to a trailer and brought to a same location where HazMat crews were able to safely off gas the CNG tank. Vehicles were then towed from the scene by Brooks Auto Service out of Winchendon and CO&S Garage out of Templeton opening the road at approximately 15:50.
Assisting on scene today with this very complicated incident were Winchendon Fire and EMS, Winchendon Police, Winchendon Dispatch, Winchendon DPW, Winchendon Town Manager Bill McKinney, Massachusetts Fire Marshal Jon Davine, MA District 6 HazMat Team, MA District 4 HazMat Team, Department of Fire Services Rehab Unit, MA State Police, MA DOT, Xpress Natural Gas, Brooks Automotive and CO&S Garage. Assisting with calls throughout the Town of Winchendon during the incident was Phillipston Fire, Ashburnham Fire, Templeton Fire and Woods Ambulance.
