"Early on, there was concern that 7 World Trade Center might have been both impacted by the collapsing tower and had several fires in it and there was a concern that it might collapse. So we instructed that a collapse area -- (Q. A collapse zone?) -- Yeah -- be set up and maintained so that when the expected collapse of 7 happened, we wouldn't have people working in it. There was considerable discussion with Con Ed regarding the substation in that building and the feeders and the oil coolants and so on. And their concern was of the type of fire we might have when it collapsed." - Chief Cruthers
"A little north of Vesey I said, we’ll go down, let’s see what’s going on. A couple of the other officers and I were going to see what was going on. We were told to go to Greenwich and Vesey and see what’s going on. So we go there and on the north and east side of 7 it didn’t look like there was any damage at all, but then you looked on the south side of 7
there had to be a hole 20 stories tall in the building, with fire on several floors. Debris was falling down on the building and it didn’t look good.
Boyle: There was a huge gaping hole and it was scattered throughout there. It was a huge hole. I would say it was probably about a third of it, right in the middle of it. And so after Visconti came down and said nobody goes in 7, we said all right, we’ll head back to the command post. We lost touch with him. I never saw him again that day.
Hayden: Yeah. There was enough there and we were marking off. There were a lot of damaged apparatus there that were covered. We tried to get searches in those areas. By now, this is going on into the afternoon, and we were concerned about additional collapse, not only of the Marriott, because there was a good portion of the Marriott still standing,
but also we were pretty sure that 7 World Trade Center would collapse. Early on, we saw a bulge in the southwest corner between floors 10 and 13, and we had put a transit on that and we were pretty sure she was going to collapse. You actually could see there was a visible bulge, it ran up about three floors. It came down about 5 o’clock in the afternoon, but by about 2 o’clock in the afternoon we realized this thing was going to collapse.
WTC Building 7 appears to have suffered significant damage at some point after the WTC Towers had collapsed, according to firefighters at the scene.
Firefighter Butch Brandies tells other firefighters that nobody is to go into Building 7 because of creaking and noises coming out of there. [Firehouse Magazine, 8/02]
Battalion Chief John Norman later recalls, "At the edge of the south face you could see that it is very heavily damaged."
[Firehouse Magazine, 5/02]
Heavy, thick smoke rises near 7 World Trade Center. Smoke is visible from the upper floors of the 47-story building.
Firefighters using transits to determine whether there was any movement in the structure were surprised to discover that is was moving. The area was evacuated and the building collapsed later in the afternoon of Sept. 11.
