Which action is included as a step upon arriving at an incident scene?

• A. Immediately arrest suspects
• B. Evacuate all personnel without assessment
• C. Disconnect all alarms at the source
• D. Notify BDOC/ECC, Establish a 360 perimeter, Assess the situation, Make contact with the alarm custodian, Confirm reason for the alarm, Conduct joint sweep with alarm custodian, Keep control center/other patrols informed, Ensure alarm reset confirm with BDOC/ECC

Answer: (D)

When you arrive at an incident scene, you must establish command, secure the area, and gather essential information before taking action. The sequence that includes notifying the BDOC/ECC, establishing a 360-degree perimeter, assessing the situation, contacting the alarm custodian, confirming the reason for the alarm, conducting a joint sweep with the alarm custodian, keeping the control center and other patrols informed, and ensuring the alarm reset is confirmed with BDOC/ECC embodies that disciplined approach. Notifying the command center activates the incident response, while the 360 perimeter containment prevents further risk and protects responders. Assessing the situation gives you the facts about hazards or threats. Contacting the alarm custodian and confirming the alarm reason ensures you understand whether it’s a true alert or a false alarm, and a joint sweep with the custodian provides a verified pass-through to check for intruders or hazards. Keeping the control center informed maintains shared situational awareness, and confirming the alarm reset with BDOC/ECC closes the loop so systems are back to normal and no residual alerts linger. In contrast, actions like making arrests without assessment, evacuating everyone without evaluating conditions, or disconnecting alarms ignore the critical steps of verification, containment, and coordination, creating greater risk and confusion.
