What code is used for explosive detection via a dog?

• A. Code 11
• B. Code 9
• C. Code 12
• D. Code 10

Answer: (A)

The code used to signal explosive-detection work with a dog is Code 11. This designation directly signals that a canine explosive-detection team is being deployed to sweep an area or respond to a threat, coordinating area security, suspect handling, and a controlled search procedure. Using this specific code keeps responders clear on the required action and reduces confusion during potentially high-pressure situations. Other codes are reserved for different alarms or operations—medical emergencies, routine checks, or unrelated incidents—so they wouldn’t indicate a canine explosive-detection response. In practice, hearing Code 11 triggers the canine unit to respond, the area to be secured, and the search to begin according to established safety protocols.
