4.2.1 Containment and Control of Vehicles
Perhaps one of the most important goals of the design of Entry Control Facilities is to ensure
that vehicles are contained through an arrangement of passive and active vehicle barrier
systems such that a threat vehicle cannot exit the entry control facility and enter the
installation upon detection. The barrier system will start at the beginning of the approach
zone and then surround the approach, access control, and response zones. Full containment
and control of vehicles is required for all ECFs. Reference 3 provides detailed guidance on
the selection and application of passive and active vehicle barriers. The aesthetics and design
of the barrier system should be consistent with the installation exterior architectural plan and
the surrounding architectural and landscape features.
4.2.1.1
Vehicle Barriers
There are two types of vehicle barriers, passive and active. Both active and passive barriers
can be fixed or movable. Active barriers require some action, either by personnel,
equipment, or both, to prevent entry of a vehicle (3). Passive barriers generally have no
moving parts and rely on the ability to absorb energy and transmit the energy to its
foundation. The design of vehicle barrier systems will be completed in accordance with
MILHDBK 1013/14 (Ref. 3), which provides a thorough discussion of the selection and
application of active and passive vehicle barriers, except as modified herein.
