1.1 The following practice is intended to address the needs and concerns of persons with implanted, active, medical devices or active ambulatory medical devices, as well as passive implanted medical devices, while maintaining the integrity of the security checkpoint.

1.2 Active and passive implanted medical devices are being used at an increasing rate as a means to prolong and improve quality of life. Although these medical devices are typically designed to operate in the electromagnetic environment experienced in daily life, there is a potential for the disruption of active medical device function when exposed to certain electromagnetic fields emitted by commonly encountered electrically powered products, including handheld and walk-through metal detectors used in security checkpoint screening. In addition, some active or passive implanted devices may trigger the unintended alarm of the metal detector.
