Exit devices, also known as panic devices or crash bars, are mechanical door hardware that is used on high-traffic doors to provide building occupants with a safe and swift exit. These devices are mounted on the interior of an outswing door and can be operated with minimal force by applying horizontal force to the device’s crossbar or push rail, which extends at least halfway across the door’s width.
According to life safety code, an exit device must always release the door without prior knowledge of how to operate the device. This means that anyone, regardless of their age or physical ability, should be able to open the door quickly and easily in an emergency.
