MWD sweeps should cover which areas when it is safe to do so?

• A. Evacuation corridors only
• B. Command post, incident post, staging areas, evacuation areas, and casualty collection points
• C. Public parking garages distant from incident
• D. Only the suspected device location

Answer: (B)

Explosive-detection dogs are used to sweep zones where a device could be placed and where people and operations are concentrated during a response. When it is safe to do so, the sweep should include the command post, incident post, staging areas, evacuation routes and assembly points, and casualty collection points. This broad coverage helps detect any secondary devices and protects responders, evacuees, and bystanders by reducing the chance that a hidden threat goes unnoticed while the incident unfolds. Limiting the sweep to only evacuation corridors or to the suspected device location misses other high-risk areas that could harbor additional devices or disrupt critical operations, and focusing on distant parking garages isn’t typically necessary unless directed by risk assessment. The comprehensive approach of sweeping key operational and assembly areas aligns with keeping the incident scene secure and the response running smoothly.
