In the months following the fire, the Illinois Inspection and Rating Bureau launched a comprehensive investigation into the McCormick Place Fire and published a detailed report on its findings. The investigators did not determine a definitive cause, but it is assumed that the temporary electrical wiring started the fire. The report did, however, shine light on many of the difficulties the firefighters faced, noting how “firefighting was seriously hampered because of lack of adequate water, intense heat, rapid fire spread, early roof collapse and unstable exterior panel walls.” The report helped to bring about numerous changes to the Chicago Municipal Code, as ordinances on exhibition halls, electrical facilities, emergency exits, fire walls, and smoke and heat vents were soon revised based on the lessons learned from the McCormick Place Fire.
