Safety and security

7-Кропачева Е.) Along with the protection offered by the reinforced concrete base, a number of other safety features were included in the building's design, in order to better prepare it for a major accident or terrorist attack. By way of comparison, the Twin Towers used a purely steel central core to house their utility functions, protected only by a system of lightweight drywall panels.

The building is no longer 8 m away from West Street, as the Twin Towers were; at its closest point, West Street is 20 m away. The windows on the side of the building facing in this direction are equipped with specially tempered blast-resistant plastic, which looks nearly the same as the glass used in the other sides of the building. In addition to optimal safety design, new security measures will also be implemented. All vehicles will be screened before they enter the site via the underground roadway, including for radioactive materials. Visitors to the National September 11 Memorial currently undergo airport-style screening as part of the "Interim Operating Period", which was expected to end on December 31, 2013. 400 closed-circuit surveillance cameras will be placed in and around the site, with live camera feeds being monitored around the clock by the NYPD. A computer system will use video-analytic computer software designed to detect potential threats such as unattended bags and retrieve images based on descriptions of terror or other criminal suspects. New York City and Port Authority police will patrol the site. Once the World Trade Center site is fully completed, the plaza will be opened entirely to the public, as was the original World Trade Center plaza.
