Firefighters notice significant damage to World Trade Center Building 7 at some point after the Twin Towers collapsed. Butch Brandies tells other firefighters that nobody is to go into WTC 7 because of creaking and noises coming out of there. [Firehouse Magazine, 9/9/2002] According to Deputy Chief Peter Hayden, there is a bulge in the southwest corner of the building between floors 10 and 13. [Firehouse Magazine, 9/2/2002] Battalion Chief John Norman will later recall, “At the edge of the south face you could see that it was very heavily damaged.” [Firehouse Magazine, 9/2/2002] Deputy Chief Nick Visconti will recall, “A big chunk of the lower floors had been taken out on the Vesey Street side.” [Firehouse Magazine, 9/9/2002] Captain Chris Boyle will say, “On the south side of [WTC] 7 there had to be a hole 20 stories tall in the building, with fire on several floors.” [Firehouse Magazine, 9/9/2002] One witness will describe looking at the south face of the building and seeing “broken windows, damage to the building, I-beams sticking out.” Another witness will describe seeing 10 to 15 floors where “the corner I-beam was missing,” and add that “there were more floors that had damage throughout the front facade of the building and several floors were completely exposed.” [Aegis Insurance Services, Inc. v. 7 World Trade Center Company, LP, 12/4/2013 
] Richard Rotanz, the deputy director of New York’s Office of Emergency Management, assesses the condition of WTC 7 at around 12:30 p.m. “We’re looking at the upper floors of Tower 7,” he will recall. “The skin of the building or the outside skirt of the building was taken out,” he will say. “You could see columns gone, floors collapsed, heavy smoke coming out, and fire.” [BBC, 7/6/2008; BBC, 10/17/2008] WTC 7 will collapse at around 5:20 p.m. (see (5:20 p.m.) September 11, 2001).

4:30 p.m. September 11, 2001: WTC Building 7 Area Is Evacuated due to Anticipated Collapse
According to numerous rescue and recovery workers, the area around World Trade Center Building 7 is evacuated at this time. [Kansas City Star, 3/28/2004] For example: 
Emergency medical technician Joseph Fortis says, “They pulled us all back at the time, almost about an hour before it, because they were sure—they knew it was going to come down, but they weren’t sure.” [City of New York, 11/9/2001] Firefighter Edward Kennedy says, “I remember [Chief Visconti] screaming about 7, No. 7, that they wanted everybody away from 7 because 7 was definitely going to collapse.” [City of New York, 1/17/2002] Firefighter Vincent Massa: “They were concerned about seven coming down, and they kept changing us, establishing a collapse zone and backing us up.” [City of New York, 12/4/2001] Firefighter Tiernach Cassidy: “[B]uilding seven was in eminent collapse. They blew the horns. They said everyone clear the area until we got that last civilian out.” [City of New York, 12/30/2001] Battalion Fire Chief John Norman: “I was detailed to make sure the collapse zone for 7 WTC had been set up and was being maintained.” [Fire Engineering, 10/2002]
Several New York Fire Department chief officers, who have surveyed Building 7, have apparently determined it is in danger of collapsing. [Fire Engineering, 9/2002] For example, Fire Chief Daniel Nigro explains their decision-making process, saying: “A number of fire officers and companies assessed the damage to the building. The appraisals indicated that the building’s integrity was in serious doubt. I issued the orders to pull back the firefighters and define the collapse zone.” [Fire Engineering, 9/2002] Fire Chief Frank Fellini says, “We were concerned that the fires on several floors and the missing steel would result in the building collapsing.” [City of New York, 12/3/2001] And Fire Captain Ray Goldbach says, “[W]e made a decision to take all of our units out of 7 World Trade Center because there was a potential for collapse.” [City of New York, 10/24/2001] However, some firefighters seem surprised at this decision. When Fire Commissioner Thomas Von Essen is making his way through hundreds of firefighters who are being held away from the WTC site, he hears complaints like, “It could take days for that building to come down,” and, “Why don’t they let us in there?” [Essen, 2002, pp. 45] When Deputy Fire Chief Nick Visconti is instructing firefighters to evacuate the area, one comment he receives is, “[O]h, that building is never coming down, that didn’t get hit by a plane, why isn’t somebody in there putting the fire out?” [Firehouse Magazine, 9/9/2002]
