Cargo Screening Procedures & Technologies Flashcards

Which cargo category requires the MOST stringent screening under TSA's layered security approach for air cargo?

Answer: Unknown shipper cargo destined for a passenger aircraft

Unknown shipper cargo destined for passenger aircraft requires the highest level of scrutiny because the shipper's background and cargo history are unverified.

What does 'resolution' mean in the context of X-ray cargo screening operations?

Answer: Investigating and clearing an anomaly identified during screening to make a security determination

In screening operations, resolution refers to the process of investigating an identified anomaly through additional screening methods until a clear security determination can be made.

Under the CCSP, which party is authorized to apply a security seal to cargo after screening?

Answer: Only a TSA-certified screener who performed or supervised the screening

Only TSA-certified personnel who performed or directly supervised the screening are authorized to apply and document the security seal on cleared cargo.

What is the significance of a 'high-risk' cargo designation in air cargo security?

Answer: It triggers enhanced screening measures and may require law enforcement notification

High-risk cargo designations require enhanced screening protocols and may trigger notification requirements to law enforcement or TSA beyond standard CCSP procedures.

How does air density variation in a cargo shipment affect X-ray screening interpretation?

Answer: Dense objects absorb more X-rays and appear darker, potentially masking threats behind them

Denser materials absorb more X-ray energy and appear darker on transmission images, and can mask threats concealed behind or within them.

Which of the following best describes a 'regulated agent' in the CCSP context?

Answer: An entity that handles, screens, or transports air cargo under a security program accepted by TSA

A regulated agent is a company or individual that accepts air cargo from shippers and handles, screens, or transports it under a TSA-accepted security program.

When using ETD swabbing on a cargo shipment, what area should be prioritized for sampling to maximize detection probability?

Answer: Exterior surfaces, seams, handles, and closure points where residue is most likely to transfer

Sampling exterior surfaces, seams, handles, and closures maximizes ETD detection because explosive residue most commonly transfers to these contact points.
