What is a panic exit device?

A panic exit device is door hardware that opens an escape door with a single, intuitive movement — even when people are pressing against it in panic. The classic image is the horizontal bar running the full width of the door: wherever you hit it, the door opens.

Two standards, two situations

The European standards distinguish by who uses the door:

Which one is required follows from the use of the building and the number of occupants. Requirements for escape routes and doors on them are set in national building regulations; where there is doubt, the building control body or fire authority decides.

Why it exists

During an evacuation, pressure builds against the door. An ordinary lock with a lever handle then becomes unusable: the door binds in the frame and the handle is out of reach. A panic exit device withdraws the latch through a movement across the whole width, so the door releases even under load.
