One example of a barrier system would be a short, concrete bull nose wall at the
beginning and end of an elevated island. By elevating the personnel on an island, they
are protected from accidental impact during identification checks. The bull nose is
designed to protect the personnel from potential injury caused by a vehicle leaving the
roadway or lane. This type of system not only enhances the safety of security
personnel, but it also offers the personnel cover in the event of an attack. Another
example would be providing 9 in (229 mm) high curbs where ID checks are performed
to increase the safety for entry controllers. However, if crash cushions or concrete
deflections are constructed in advance of these positions, the curbs should be 6 in
(152mm) high so that the checkers are not too high above the seated drivers.
See the RSDG-3 for further information concerning barriers and crash cushions. The
maximum height of crash protection barriers will be 3 ft (1 m) or the elevation of the
guard facility window sills, which ever is less, to avoid conflicts with traffic or guard
sightlines.
