Ga. teacher invents lockdown safety device that could help prevent school shootings

GWINNETT COUNTY, Ga. — A seventh-grade teacher at Dacula Middle School in Georgia invented a simple device designed to keep children safe in the event of a school shooting, according to WGCL.

Celisa Edwards told WGCL she loves teaching children but has been bothered by the 2012 shooting at Sandy Hook. She felt obligated to design the device to keep her children safe.

The Portable Affordable Lockdown Device, also known as PALS, is a steel rope encased in plastic that loops over a door handle and attaches to an eye bolt in wall.

The device can secure the door in the event of a school shooting or other security incident at the school. Edwards said a patent is pending.

The device costs $70.
