The building was severely damaged in the September 11 attacks when the South Tower of the World Trade Center collapsed 300 feet ( 91m ) away . Scaffolding which had been erected on the facade for renovation work did nothing to stop the fiery debris from raining down on the building and tearing a number of large gashes deep into its northern face . Two office workers were killed when they were trapped in an elevator . The firestorm raged out of control for several days ; the building , which had housed businesses including Hanover Capital , Frost & Sullivan , and IKON Office Solutions , was completely gutted . It is believed that 90 West 's heavy building materials and extensive use of terra cotta inside and out helped serve as fireproofing and protected it from further damage and collapse , as opposed to the more modern skyscraper at 7 World Trade Center , which suffered similar damage and collapsed later that day
