How should a suspected device be cordoned to prevent secondary hazards?

• A. Place a single tape line and do nothing else.
• B. Allow unrestricted access for investigators.
• C. Establish a safe exclusion zone with clear boundaries, barricades, access control; maintain standoff distances.
• D. Use only verbal warnings without barriers.

Answer: (C)

Establishing a safe exclusion zone with clear boundaries, barricades, and controlled access while maintaining appropriate standoff distances is essential to prevent secondary hazards when a device is suspected. Physical barriers and a defined perimeter keep bystanders and potential interfering personnel away from the device, reducing the chance of triggering the device or being exposed to fragmentation, shrapnel, or an unintended detonation. The exclusion zone also gives responders space to observe, assess, and apply safer techniques without outside interference, which is critical for the integrity of the operation and for personal safety. In contrast, a single tape line, unrestricted access, or only verbal warnings do not provide real protection or control; they fail to establish the necessary distance or barriers to prevent accidental contact or tampering.
