Communication During The September 11 Attacks - First Responders

First Responders

After the 1993 World Trade Center bombing, radio repeaters for New York City Fire Department communication were installed in the tower complex. Because they were unaware that several controls needed to be operated to fully activate the repeater system, fire chiefs at their command post in the lobby of the North Tower thought the repeater was not functioning and did not use it, though it did work and was used by some firefighters. When police officials concluded the twin towers were in danger of collapsing and ordered police to leave the complex, fire officials were not notified. Fire officials on the scene were not monitoring broadcast news reports and did not immediately understand what had happened when the first (South) tower did collapse.

There was little communication between New York City Police Department and fire department commands even though an Office of Emergency Management (OEM) had been created in 1996 in part to provide such coordination. A primary reason for OEM's inability to coordinate communications and information-sharing in the early hours of the WTC response was the loss of its emergency operations center, located on the twenty third floor of 7 World Trade Center which had been evacuated after debris from tower's collapse struck the building, igniting several fires.

Emergency relief efforts in both Lower Manhattan and at the Pentagon were augmented by volunteer amateur radio operators in the weeks after the attacks.
