The Philips Lifeline Personal Help Button Necklaces pose a possible hazard according to the FDA. There have been at least six reports of serious injury or death associated with the emergency alert pendants.
The emergency alert pendant is designed not to break away when tugged; yet because of its durability it poses a hazard if it becomes tangled around another object.
Between 1998 and 2009, there have been four deaths and two serious injuries associated with the device.
Philips Lifeline has alerted its 750,000 customers to the potential risk. The agency recommends individuals consult with their physician to determine which style of emergency alert button is appropriate for their use.
