✍️ Sample TSO Questions & Answers

1. What is the primary advantage of a dual-energy X-ray system over a single-energy system for TSOs?

✓ It provides separate images for organic and inorganic materials, improving threat detection

Dual-energy X-ray systems use two energy levels to differentiate organic from inorganic materials, making it easier to identify potential threats.

2. Which martial arts weapon is prohibited in carry-on baggage?

✓ Nunchucks

Nunchucks are prohibited in carry-on baggage because they are impact weapons; they may be transported in checked baggage.

3. A passenger wishes to travel with a self-defense spray. Under what specific conditions is this item permissible for air travel?

✓ It is allowed in checked baggage only, in a container of 4 fl. oz. (118 ml) or less, and equipped with a safety mechanism.

TSA permits one 4 fl. oz. (118 ml) container of mace or pepper spray in checked baggage only. A critical requirement is that the container must have a safety mechanism to prevent accidental discharge. Self-defense sprays are prohibited in carry-on baggage.

4. A TSO observes an X-ray image with an object that appears as a solid orange rectangle with no distinguishable internal structure. What is the most appropriate response?

✓ Flag the bag for additional screening because solid undifferentiated masses can conceal threats

Solid undifferentiated masses with no visible internal structure are a concealment red flag and warrant additional screening to identify the contents.

5. A passenger nervously watches TSO officers while repeatedly checking their carry-on bag and avoiding eye contact. This behavior is best described as:

✓ A behavioral indicator requiring further observation

Repeated checking of baggage combined with surveillance-like watching of officers are behavioral indicators that warrant additional observation.

6. Which of the following items is permitted in a passenger's carry-on baggage, according to TSA guidelines?

✓ Knitting needles and scissors with blades less than 4 inches from the pivot point.

Knitting needles are permitted in carry-on baggage. Scissors with a blade length of less than 4 inches from the pivot point are also allowed. Pepper spray and most tools are prohibited in carry-on. All knives, except for plastic or round-bladed butter knives, are prohibited.
