The liquid bomb plot led to which security procedure?

• A. 4-2-2 medications limit
• B. 1-2-3 carry-on limits
• C. 3-1-1 liquids rule (August 2006)
• D. 2-2-2 bag sizes

Answer: (C)

This is about how aviation security adapted to the risk of liquids by restricting what you can carry onto a plane in your hand luggage. The liquid bomb plot showed that small amounts of liquid, gels, or aerosols could be used to assemble an explosive, so authorities introduced strict limits to prevent large quantities from being brought through security. The policy introduced in August 2006 specifically targets liquids in carry-on bags. Each container must be 100 ml (3.4 oz) or smaller, all containers must fit inside a single clear, resealable bag of about 1 liter in capacity, and the bag must be presented at screening. This is why you’ll often hear it referred to as the 3-1-1 rule: 3 ounces per item, 1 bag, 1 passenger. This rule applies to liquids you carry into the cabin; larger amounts can be placed in checked baggage. Other options don’t reflect this response to the plot because they describe different, unrelated limits or policies. The 3-1-1 liquids rule directly addresses the risk demonstrated by the incident and remains a cornerstone of security procedures for air travel.
