What is the first action in the sequence of responses to an explosion or significant incident?

• A. Call a supervisor only.
• B. Ignore and wait for formal orders.
• C. Evacuate, secure the area, notify supervisors and EOD, assess and treat casualties, preserve evidence, and begin investigation.
• D. Wait for a formal written order.

Answer: (C)

Immediate life safety and scene control drive the first actions. In an explosion or significant incident, you start by evacuating people from danger and securing the area to limit exposure to hazards and prevent further harm. At the same time, you notify the right people—supervisors and Explosive Ordnance Disposal (EOD) if ordnance could be present—so trained responders can take over with the proper procedures. Once safety is established, provide casualty assessment and treatment as needed, while preserving the scene to support the investigation. Preserving evidence and beginning the investigation follow once people are safe and the area is secured. This sequence ensures that lives are protected first, responders are mobilized appropriately, and the incident is documented for a proper, thorough resolution.
