List 3 types of patrol types you may be required to conduct whilst on shift.

• A. Internal
• B. External
• C. Alarm response
• D. All of the above

Answer: (D)

Patrols on shift cover both what you do inside a site, what you monitor outside, and how you handle incidents that trigger alarms. Internal patrols involve moving through the building to check that doors and windows are secure, restricted areas remain controlled, and any hazards or suspicious activity are noted and reported. External patrols focus on the outside perimeter—fences, gates, lighting, and access points—looking for signs of tampering, unauthorized entry, or safety issues along the outer boundary. Alarm response patrols come into play when an alarm is triggered; you follow the established procedures to verify the alarm, assess the scene safely, contact the control room or authorities if needed, and document the incident.

Because all three types represent common, essential duties you may be asked to perform during a shift, the best answer is all of the above. Focusing on only one type would leave gaps in security coverage, whereas combining interior checks, exterior vigilance, and swift alarm response provides a complete approach to safeguarding the site.
