Security Screenings

The Transportation Security Administration manages the security screening of passengers and baggage at William P. Hobby Airport.

Advanced imaging technology safely screens passengers for both metallic and non-metallic threats, including weapons and explosives. The technology detects items which may be hidden under a passenger's clothing. It allows TSA to screen without physical body contact and works to keep the traveling public safe. Millimeter wave imaging technology bounces safe electromagnetic waves off of the human body to create a black and white image, similar to a fuzzy photo negative. TSA began deploying 450 advanced imaging technology units in Marc 2010. These units were purchased with American Recovery and Reinvestment Act (ARRA) funding.

TSA has 204 imaging technology units at 52 airports currently and plans to install 450 imaging technology total units in 2012.

How Screening Works

Advanced imaging technology is completely optional for all passengers. However, passengers who opt out of imaging technology screening will receive alternative screening, which includes a physical pat-down. The security officer will ask a passenger to remove all objects from his/her pockets prior to entering the portal. This officer never sees the passenger's image. A second security officer in a walled-off location sees the black and white image made by the technology. Once this second officer reviews the image and resolves any anomalies, the image is immediately deleted. This entire screening process takes mere seconds.

Screening Privacy Features

TSA has implemented strict measures to protect passenger privacy by making the image used anonymous. The image cannot be stored, transmitted or printed and is deleted immediately after viewing and approved for clearance. The technology also has a privacy filter that blurs facial features.

Screening Safety Features

Millimeter wave technology screening is safe for all passengers and meets all known national and international health and safety standards. The energy emitted by millimeter​ wave technology is thousands of times less than what is allowable for a cell phone.
