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:
- EN 1125 — panic exit device. For places used by members of the public unfamiliar with the door: theatres, shops, sports halls, schools, stations. Operated by a horizontal bar (push bar or touch bar), so that even someone pressed against the door opens it.
- EN 179 — emergency exit device. For places where the occupants know the door and panic is unlikely: offices, industrial premises. Operated by a lever handle or push pad.
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.
Practical points
- The door must swing in the direction of escape. Hardware on an inward-opening door does not help when pressure builds.
- No additional locks, bolts or chains on an escape door — the most common and most dangerous breach in practice.
- Outside face: a panic device may be lockable from outside (blank plate, or outside access with a cylinder), as long as the inside always opens freely.
- Combination with fire resistance: if the door is also a fire door, the hardware, closer and device must have been tested and certified together. Swapping individual components voids the certification.
- Maintenance: panic devices take heavy use and collect dirt. Put them in the annual maintenance schedule and actually test them, not just on paper.
- Door closers: an escape door with a closer must still be openable by the weakest user; over-strong closers are a known problem.
