Fires Have Never Caused Skyscrapers to Collapse
<table class="figure_right" align="right" width="200"> <tbody><tr> <td>
</td> </tr> <tr> <td> [SIZE=-1] The One Meridian Plaza fire [/SIZE] </td> </tr> </tbody></table> Excepting the three 9-11 collapses, no fire, however severe, has ever caused a steel-framed high-rise building to collapse. Following are examples of high-rise fires that were far more severe than those in
WTC 1 and
2, and
Building 7. In these precedents, the fires consumed multiple floors, produced extensive window breakage, exhibited large areas of emergent flames, and went on for several hours. The fires in the WTC towers did none of these things.
The One Meridian Plaza Fire
One Meridian Plaza is a 38-floor skyscraper in Philadelphia that suffered a severe fire on February 23, 1991. The fire started on the 22nd floor and raged for 18 hours, gutting eight floors and causing an estimated $100 million in direct property loss. [SIZE=-1] <sup> </sup>[/SIZE][SIZE=-1]<sup>

The fire caused window breakage, cracking of granite, and failures of spandrel panel connections. [SIZE=-1] <sup>

The First Interstate Bank Fire
The First Interstate Bank Building is a 62-story skyscraper in Los Angeles that suffered the worst high-rise fire in the city's history. From the late evening of May 4, 1988 through the early morning of the next day, 64 fire companies battled the blaze, which lasted for 3 1/2 hours. The fire caused extensive window breakage, which complicated firefighting efforts. Large flames jutted out of the building during the blaze. Firefighting efforts resulted in massive water damage to floors below the fire, and the fire gutted offices from the 12th to the 16th floor, and caused extensive smoke damage to floors above. The fire caused an estimated $200 million in direct property loss. [SIZE=-1] <sup> </sup>[/SIZE][SIZE=-1]<sup>

A report by

It suffered a severe fire and explosion on August 5, 1970. The fire started around 6 PM, and burned for more than 6 hours. [SIZE=-1] <sup> </sup>[/SIZE][SIZE=-1]<sup>

Caracas Tower Fire
The tallest skyscraper in Caracas, Venezuela experienced a severe fire on October 17, 2004. The blaze began before midnight on the 34th floor, spread to more than 26 floors, and burned for more than 17 hours. Heat from the fires prevented firefighters from reaching the upper floors, and smoke injured 40 firefighters.
Lax enforcement of fire codes in Venezuela was blamed for the malfunctioning of water pumps and a lack of fire extinguishers inside of the building. Because the building was empty when the fire broke out, no civilians were killed or injured. [SIZE=-1] <sup> </sup>[/SIZE][SIZE=-1]<sup>

The Windsor Building Fire
<table class="figure_right" align="right" width="320"> <tbody><tr> <td>
</td> </tr> <tr> <td> [SIZE=-1] The Windsor Building fire [/SIZE] </td> </tr> </tbody></table> The most recent case of a severe high-rise fire is the one that destroyed the Windsor Building in Madrid, Spain on February 12, 2005. The Windsor fire was more severe than any of the other fires described on this page, and the incident has been widely publicized, with comparisons to the fires in the three World Trade Center skyscrapers on 9/11/01. However, the Windsor Building, unlike all the buildings mentioned above, was framed in steel-reinforced concrete rather than steel. Hence it is described on a
separate page, which notes differences between the response of these different types of structures to fires.
