Joining us today is deputy chief Steve Calvin of the hackers -- -- -- Back in July 1 1988. Hackensack fire department suffered a fire -- -- at Ford dealership.

The difference at the -- fire which was an auto dealership was that the -- truss -- was concealed. And the main body of fire was in the -- areas involving -- materials.

Of fighting fire truss construction. Couple of the construction features of this building that we wanna point out are the ability of the fought apartment like that -- by the trust is from the exterior of the building. As we view the -- we can identify the areas of support by the brick columns that are constructed. Into the exterior walls. These brick columns are visible from the exterior for the firefighters to recognize. We're the -- are supported on the exterior wall. We also noticed as we move the camera through the building. That this is actually double trust me that's who trusses are lined up in the same horizontal plane standing side to side of the building. Once trust is actually open there's no trust -- it's a wide -- trust things. The other part of the building where the second trusses supported is actually in a concealed space. That is a danger to the fire service of firewood -- to -- -- that concealed space or originate that concealed space the fire and growing intensity. Posing significant damage that I trust me -- failure that trust and a large area collapse. As I mentioned earlier one of the first actions taken by the department.
