Fellow Hoosier: I was onsite during the (1991?) Merom Generating Station fire in one scrubber module. The fuel was a plastic packing such as polypropylene ignited by oxyacetylene cutting slag. The fire burned for many more hours than any WTC buildings. I was among the first to inspect the structure the following morning as a mechanical engineer with steel structure experience. I observed no molten metal, several warped 12 inch horizontal I-beams and columns along with smaller girters. I inspected all the structural steel including bolted connections and determined that it was safe for human occupancy for the purpose of rebuilding the scrubber module.
