Explosives Trace Detection and Alarm Resolution Flashcards

Which statement best describes the relationship between a 'clear' ETD result and security?

A clear ETD result only means no threat signature was found on the sampled surfaces; it doesn't rule out every prohibited item.

During ETD screening of a passenger with a disability, what should the officer do?

Officers adjust techniques to accommodate disabilities and medical devices while still completing the required screening.

A child's toy alarms on ETD. How should the officer proceed?

Answer: Resolve the alarm using standard procedures, the same as any other item

Any alarmed item has to be resolved through procedure no matter what type of item it is or who owns it.

Why do ETD procedures commonly include swabbing a passenger's hands?

Answer: People who handle explosives often have residue on their hands

Explosive residue easily sticks to the hands of anyone who has handled explosive materials, which makes hands an effective place to sample.

What should an officer do if a passenger becomes agitated during ETD alarm resolution?

Answer: Stay calm and professional and request supervisor help if needed

Calm, professional communication and getting a supervisor involved when needed help de-escalate the situation without compromising security.

How often should ETD swabs and consumables be replaced or managed?

Answer: According to manufacturer and TSA procedures, including after alarms

Following the required schedules and post-alarm replacement keeps detection reliable and prevents contamination.

An ETD alarm happens on a sealed medical item a passenger needs. What is the best approach?

Answer: Resolve it according to procedure while handling the medical item carefully and respectfully

Medical items still need alarm resolution, but officers must handle them carefully and follow any special procedures for medically necessary items.
