When viewing an X-ray image, a TSO sees an object shaped like a pistol but rendered entirely in orange. What should the officer conclude?
Answer: The shape warrants resolution regardless of color because firearms can be made of polymer or plastic
Polymer-framed or 3D-printed firearms display as organic (orange) but retain their characteristic shape, which must still be resolved.
Which action should a TSO take when they cannot conclusively resolve an anomaly on the X-ray image?
Answer: Refer the bag for additional screening such as ETD testing or a physical search
An unresolved anomaly must be escalated to additional screening methods; clearing an ambiguous bag creates a security gap.
A syringe appearing in an X-ray image typically displays as which combination of features?
Answer: A thin, elongated shape with a denser needle tip and a lighter barrel
Syringes show a tapered metal needle at one end and a hollow plastic barrel, creating a characteristic two-density elongated silhouette.
What is 'threat image projection' (TIP) and why is it used during X-ray screening?
Answer: A training tool that inserts simulated threat images into real bag scans to test officer alertness
TIP overlays fictitious threat images onto live X-ray scans to evaluate and maintain officer detection performance without real threats.
A bag shows a large, dense white rectangular block that fills much of the image and has no visible internal detail. This is most consistent with:
Answer: A lead-lined bag intended to block X-rays, which itself is cause for additional screening
Lead-lined bags are designed to block X-rays and produce a featureless bright white rectangle; TSA policy requires additional screening when contents cannot be evaluated.
During X-ray image review, what does a 'void' or unexplained empty dark area within an otherwise dense object suggest?
Answer: A possible hidden cavity that could contain a concealed threat item
Unexplained voids within dense objects may indicate hollowed-out items used to conceal weapons, drugs, or explosive material.
An X-ray image shows a cylindrical object approximately 12 inches long with end caps, internal wiring, and a powdery fill. This profile is consistent with:
Answer: A pipe bomb, requiring immediate lane alarm and supervisor notification
A capped cylinder with wiring and granular fill matches a classic pipe bomb signature and must be treated as an imminent threat.
