When you become a firefighter, if you want to become certified you have to get a lot of training. One area of training is building construction. Firefighters need to know about it in order to predict how fire will travel and extend, how to proceed with attack, and what to be concerned about for firefighter safety as the time of burning continues. One of many things that has stuck with me is the difference in how long wood will last in a fire compared to steel. Believe it or not, other things being equal, STEEL CONSTRUCTION WILL COLLAPSE SOONER THAN WOOD CONSTRUCTION. The reason for this is that wood beams that hold up all wood structures will not bend due to heat, They have to burn from outside in, which regardless of temperature takes time. Steel on the other hand needs to be at a certain temp for a matter of minutes before it looses its strength. We have all watched the twin towers fall once those minutes had passed. True steel is encased in insulation, but wood is easily protected by fire rated sheetrock as well as insulation as in my building.
