A fire at a Ford Dealership that led to the deaths of five firefighters.   The incident started just before 3 p.m. in the rear service area of the dealership and while firefighters were operating inside the structure, an approximate 60-foot section of the roof had collapsed.  A group of investigators from T.J. Russo Consultants and recommended companies were retained to conduct the origin and cause analysis into the fire and collapse.   Our team worked alongside the Bergen County Arson Squad regarding the design and construction of the truss roof, the impact of varying fuel loads, flame spread above the shop area, the fire-ground operations and more.
