Enforce a standoff zone:A standoff zone is a secure area in which only pre-screened vehicles, bicycles, etc. are allowed to enter. A 100- to 300-foot standoff zone is ideal, but the effects from a blast are decreased in direct correlation to the increase in distance between a blast and its intended target. Therefore, even a 10-foot standoff zone is better than no standoff zone. Bollards, barriers and barricades (natural and man-made) enforce the integrity of the standoff zone.
Implement surveillance detection:: Nearly every major terrorist attack has been preceded by months and years of surveillance. Initial surveillance is usually conducted by amateurs or unwitting accomplices – children, taxi drivers, delivery/service persons, etc. – paid to take photographs, provide facility descriptions or other information (or information is surreptitiously elicited from them). Once a target list is narrowed, comprehensive surveillance is conducted by professional operators. Security personnel should be trained to observe and report unusual interest in a facility or activities that are out of context for the environment (e.g. a taxi driver photographing a service entrance). As planning progresses, operators may conduct tests or dry runs, such as attempting to enter a restricted door to test the security response, or driving the intended route to identify potential obstacles.
Screen deliveries:All delivery, service and courier vehicles and their contents should be screened using the following procedures:
- deliveries, other than courier services, should be scheduled in advance, and drivers should be required to present a bill of lading that reflects the driver’s name and a password issued by the Receiving Department;
- all drivers, including couriers, and their assistants should present photo identification and their presence should be documented;
- all license tags should be documented;
- ideally, cargo should be inspected by security at a remote location and sealed by security until arrival in the receiving area, where the seal is broken by building security or a receiving clerk/dock master;
- all incoming parcels should be x-rayed or physically inspected; and
- no parcels should be accepted anywhere other than at the designated receiving area.
