After 9-11, New Safety Measures For Skyscrapers

One of the first skyscrapers to be designed after 9-11, the 7 World Trade Center building uses new safety measures.

"Eleven inches could be a matter of life and death.So the designers of the new 7 World Trade Center, planned by Silverstein Properties, have called for fire stairs 66 inches wide, rather than the 55 inches specified by the New York code for such a building. They say that will allow room for two-way traffic: occupants going down and firefighters coming up."
