Bottled Liquid Scanners

Innovation & Technology

Bottled liquid screening systems are  screening technologies that differentiate liquid explosives from common, benign liquids. TSA utilizes this technology at checkpoints across the country, where it is used primarily to screen medically necessary liquids in quantities larger than three ounces

TSA is currently testing new liquid screening systems with enhanced detection capabilities and use light waves to screen sealed containers for explosive liquids.

Following the disruption of the UK/US airline bombing plot in August 2006, TSA issued new rules that, with a few exceptions, effectively banned liquids, gels, and aerosols on aircraft. After conducting extensive research, TSA determined small amounts of liquids are not a threat. On September 26, 2006, TSA permitted small amounts of liquids, gels and aerosols in travel size containers, and exempted baby formula/milk/juices, medicines, and other medically-required liquids.
