  1. A passenger's carry-on contains a bottle of wine (750 ml) purchased before the checkpoint. What is the correct ruling?

    Answer: Prohibited; all alcohol over 3.4 oz is banned in carry-on

    All liquids, including alcohol purchased before the checkpoint, must comply with the 3-1-1 rule; bottles over 3.4 oz are prohibited unless purchased past the security checkpoint.

  2. Which type of firearm magazine or clip rule applies to checked baggage?

    Answer: Magazines and clips must be unloaded and may be transported in checked baggage

    Unloaded firearm magazines and clips are permitted in checked baggage; loaded magazines are prohibited because loose ammunition must be properly contained.

  3. A passenger presents a personal water bottle that is full of water. How should the TSO handle this?

    Answer: Require the passenger to empty it before proceeding through the checkpoint

    Passengers must empty reusable water bottles before the checkpoint; empty bottles can pass through and be refilled after security.

  4. Which of the following is permitted in carry-on baggage?

    Answer: CO2 cartridge bicycle tire inflator (small, max 75g CO2)

    Small CO2 cartridges up to 75g used for bicycle tires are permitted in carry-on; the other items are prohibited due to compressed gas or hazardous content.

  5. A passenger has a checked bag with a firearm. They claim it is locked but the TSO cannot verify this at the checkpoint. What is the correct action?

    Answer: Require the passenger to demonstrate that the container is locked before accepting it

    TSA requires that firearm containers in checked baggage be locked with a non-TSA lock; the passenger must demonstrate the container is locked before it is accepted.

  6. Which of the following liquids is EXEMPT from the 3-1-1 rule when carried in reasonable quantities?

    Answer: Baby formula and breast milk for infants traveling with the passenger

    Baby formula, breast milk, and juice for infants or toddlers are exempt from the 3-1-1 rule in reasonable quantities when a child is traveling with the passenger.

  7. A passenger's bag triggers an alarm for explosive trace detection (ETD). The follow-up ETD swab also tests positive. What is the next step?

    Answer: Conduct a thorough physical bag search and if still unresolved, involve law enforcement

    A confirmed positive ETD result requires a thorough physical inspection of the bag, and law enforcement must be notified if the alarm cannot be resolved.
