✍️ 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.
