Why this door type
Why panic hardware particularly benefit from a service contract
Panic hardware is the door type with the most direct life-safety implication. The Responsible Person's baseline duty under the RR(FS)O 2005 is monthly user-test of every emergency exit. On top of that, BS EN 1125 / BS EN 179 require annual professional inspection. Hardware that's been modified, painted over, or had non-certified parts substituted is non-compliant from the moment of modification — and the consequences in a fire-evacuation scenario can be catastrophic. A service contract gives the Responsible Person ongoing documented evidence and catches certification-invalidating modifications.
The compliance angle
BS EN 1125 covers panic hardware for public emergency exits (horizontal push-bar). BS EN 179 covers emergency exit hardware for trained users (levers, push-pads). Both require CE / UKCA marking with a 10-digit performance code. Locking the inside operation in any way (chains, padlocks, screws, kick-plates over the bar) is illegal under the RR(FS)O 2005. The Responsible Person is personally liable.
