Access Control and Patrol Procedures
Access control ensures that only authorised people, vehicles, and goods enter or leave a site. A candidate must understand the components: identification and verification, visitor registers, issuing and controlling passes, vehicle checks, and the control of materials leaving the site (gate passes, delivery notes). The principle is 'verify, record, and control'. You confirm identity against an authorised list or document, record the entry or exit, and control what passes the point.
Key concepts: the difference between identification (who you are) and authorisation (whether you may enter); the visitor register with name, ID, time in, time out, and host; the use of a challenge procedure for unknown persons; and the handling of deliveries against documentation. Patrol procedures include the purpose of patrols (deterrence, detection, and reassurance), the types of patrol (foot, vehicle, internal, external), the use of patrol clocks or checkpoints, and the importance of varying routes and times so patrols are not predictable. You must know how to record patrols accurately and how to report anomalies such as unlocked doors, broken lights, or suspicious items.
Traps in questions: letting in a familiar face without verification; accepting a verbal claim of authority; failing to record time out; assuming a patrol is only about walking a route (it is about observation and reporting); and touching or moving a suspicious object instead of securing the area and reporting it. Another trap is being pressured to skip a checkpoint because 'nothing ever happens'.
Rule of thumb: no verification, no entry; record every movement in and out. Worked example: a delivery driver arrives at 02:00 claiming an urgent delivery. You do not open the gate on the claim alone. You verify the driver's identity, confirm the delivery against the authorised delivery schedule or by phoning the on-site contact, record the vehicle registration, name, and times, and only then allow entry, directing the vehicle to the designated loading area.
