TSO Prohibited Items and Threat Recognition 2 — Questions and Answers
Question 1: A passenger's carry-on contains a snow globe larger than a baseball. What is the correct action?
- Allow it if the liquid inside appears clear
- Prohibit it regardless of liquid clarity (Correct answer)
- Test the liquid with a chemical strip before deciding
- Allow it only if the passenger declares it
Correct answer: Prohibit it regardless of liquid clarity
Snow globes larger than a baseball are prohibited in carry-on baggage regardless of apparent liquid content because their size makes liquid volume unverifiable.
Question 2: Which of the following tools is generally permitted in carry-on baggage?
- A hammer with a 12-inch handle
- A screwdriver longer than 7 inches
- A small flathead screwdriver under 7 inches (Correct answer)
- A box cutter with a retractable blade
Correct answer: A small flathead screwdriver under 7 inches
Tools shorter than 7 inches (measured from the end of the handle) are permitted in carry-on baggage, while longer tools must be checked.
Question 3: What does the term 'artfully concealed' mean in the context of TSO threat recognition?
- Items stored in TSA-approved containers
- Prohibited items hidden within everyday objects to avoid detection (Correct answer)
- Liquids packed in clear ziplock bags
- Sharp objects wrapped in clothing
Correct answer: Prohibited items hidden within everyday objects to avoid detection
Artfully concealed refers to prohibited items deliberately hidden inside ordinary objects such as books, electronics, or food containers to evade X-ray detection.
Question 4: A passenger presents a medically necessary syringe but has no prescription label. What should the TSO do?
- Confiscate the syringe immediately
- Allow it without any additional screening
- Resolve the situation through additional screening and consult a supervisor if needed (Correct answer)
- Deny boarding to the passenger
Correct answer: Resolve the situation through additional screening and consult a supervisor if needed
TSOs should apply additional screening measures for declared medical syringes and escalate to a supervisor when documentation is absent but the claim appears legitimate.
Question 5: Which of the following best describes a 'dual-use' item in aviation security?
- An item that can be used in both domestic and international flights
- An item that is harmless in normal use but can potentially be used as a weapon (Correct answer)
- An item that must be screened twice
- An item approved for both carry-on and checked baggage
Correct answer: An item that is harmless in normal use but can potentially be used as a weapon
Dual-use items are everyday objects—such as walking canes, umbrellas, or sporting equipment—that serve legitimate purposes but could be weaponized.
Question 6: A firearm magazine loaded with ammunition but without an attached firearm is discovered in a carry-on. What is the correct classification?
- Permitted if the magazine is in a locked container
- Prohibited; treat it the same as a loaded firearm (Correct answer)
- Permitted because there is no attached firearm
- Permitted if the passenger has a concealed carry permit
Correct answer: Prohibited; treat it the same as a loaded firearm
Loaded firearm magazines are prohibited in carry-on baggage and must be transported in checked baggage in a hard-sided, locked container.
Question 7: Which behavioral indicator might suggest a passenger is attempting to smuggle prohibited items through the checkpoint?
- Making eye contact with TSOs and greeting them politely
- Voluntarily removing shoes and laptop before being asked
- Avoiding eye contact, appearing excessively nervous, and repeatedly checking surroundings (Correct answer)
- Wearing loose-fitting clothing appropriate for air travel
Correct answer: Avoiding eye contact, appearing excessively nervous, and repeatedly checking surroundings
Behavioral detection officers are trained to identify clusters of indicators such as avoidance of eye contact, excessive nervousness, and hypervigilance as potential signs of deceptive intent.
