Just a small example of fire destablizing a steel structure:
My Father's engineering company had a fire in one of the labs where they made curcuit boards. The fire fed off the chemicals in the boards and managed to weaken the steal support for the roof. The main beam partially liquified in about an hour and the entire roof caved in. This was a single story building with no excesive weight on the roof structure. Now I point this out because there were probably countless computers in all of these building that contributed a ton of chemicals that need to be accounted for. Factor in that most of these come from China and you probably have very little idea what was acctually burning in those fires.
Anyway, food for thought.
