Teacher’s invention could protect kids from school shootings

(CNN) – School shootings, like the one in Oregon Tuesday, have led a few Iowa teachers to take action. They have invented a device they say will secure their classrooms and help keep students safe.

“That their parents have entrusted me with their safety.” It’s something that no teacher wants to think about.

“I’m going into a place that’s become a target.” What to do if there’s a shooter in the building.

“I have a wife who’s a kindergarten teacher and I’m going, how can I protect my wife in a situation like that.”

Recent shootings like the one in Oregon on Tuesday have raised awareness, but a few teachers in Muscatine were tired of waiting for a better solution to keep their classrooms safe.

“When violence occurs in a school, teachers have seconds to make a potentially life saving decision.”

In his training, middle school teacher Daniel Nitzel was taught to tie a belt around the door’s closer arm, something he and his colleagues quickly realized was not a great option.

“All 5 rooms that the teachers were trained in, the doors were breached, the cords were ripped, and the police officer who was portraying the active shooter came in and killed all of us.”

That’s when he went home and designed “The Sleeve”, a 12-gauge carbon steel case that goes over the door’s closer arm, securing it from the inside.

Once the sleeve is on the door, it takes an incredible amount of force for the door to be opened, making it nearly impossible for the shooter to get inside the room. “I think it’s a great product.”

“These shooters, they’re going to be pulling on the door. If they can’t get in, they’re going to move on.”

Nitzel stresses that it’s no replacement for a door lock, and should only be used in an emergency.

“We look at it as a cheap insurance policy. If you have someone out in the hallway, and you do not want to go out into the hallway and lock your door, we want to provide you with a way to disarm that door.”

A simple and yet effective way that could mean the difference between life and death.

The sleeve is still awaiting a patent. But one local college is reportedly already fitting all its classrooms with the device.
