I have personally been called to several electric gym divider accidents, the most recent in Chicago . A 15 year old girl was playing hockey in the gym at jones prep College High school , the puck got caught in the curtain as it started rolling up from the floor. Her arm became trapped  , she was rolled up like a hotdog 25 feet in the air until she could be rescued by the fire dept.  This could have easily resulted in her being suffocated or falling to her death.

Two incidents happened in NJ several years ago involving electric curtains, I was on site at both of these locations as well. One curtain detached from the brackets as it was being retracted up to the ceiling, missing the operator and students in gym class by only inches. This curtain was over 25 feet long weighing hundreds of pounds, this too could have caused serious injury or death to multiple occupants.

 Another incident which I evaluated after being called to , was a 12 year old young man having his sweatshirt hood caught in the gym curtain as it was retracting into the ceiling ,If this student was not able to wiggle out and jump to safety, he could have been hung.

I am also aware of a young lady being trapped under the bar of the electric curtain as it came down from the ceiling, her gym class all helped lift the several hundred pound steele  pipe as she was pulled to safety.
