What are the steps for response considerations upon arrival at an incident scene?

• A. Notify local authorities only
• B. 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
• C. Establish a 180-degree perimeter
• D. Delay all actions until supervisor arrival

Answer: (B)

The main idea is to follow a coordinated, rapid-response workflow that builds situational awareness, secures the scene, and closes the loop with control and the alarm custodian. On arrival, the first priority is to notify the BDOC/ECC so the incident is logged and the right personnel can be mobilized. Establishing a 360-degree perimeter immediately ensures all approaches are covered and there is a safe, controlled environment for responders and any needed investigations. A quick assessment of the scene then helps you identify hazards, entry points, and potential threats, shaping how you proceed.

Contacting the alarm custodian is essential to verify what triggered the alert and gather context about the specific alarm zones involved. Confirming the reason for the alarm helps you determine whether this is a legitimate event or a false alarm, avoiding unnecessary escalation. Conducting a joint sweep with the alarm custodian ensures both parties share local knowledge of the alarm system and the area, increasing the likelihood of a thorough check without overlooking anything.

Keeping the control center and other patrols informed maintains a clear shared picture of the situation, which supports coordinated action and safety. Finally, you confirm with BDOC/ECC that the alarm has been reset before clearing the scene to close the incident properly and prevent premature clearance.

Why the other options don’t fit: notifying local authorities alone misses the internal coordination, containment, and verification steps that are critical to a controlled response. A 180-degree perimeter leaves significant gaps and blind spots, reducing safety and effectiveness. Delaying actions until a supervisor arrives is unsafe and contrary to standard operating procedures, which expect responders to initiate the documented steps immediately upon arrival.
