Obviously not a proper fire door (no latching), but it doesn’t look like the inside (where the photographer was standing) suffered too much damage. The lites failed, however, so the inside area was probably full of smoke.
You’re right, Elias…this isn’t a fire door by our standards. It’s in the UK so maybe the rules are different – I’m not sure. Even without the latching, the closed door was able to contain most of the smoke and flames. Proper fire doors (including latching) are important, but if the doors are propped open they can’t do their job.
I’ve never seen any data on this. A couple of years ago I checked with NFPA’s One-Stop Data Shop and they had no data at all. They sent me a compilation of a bunch of fires where doors had an impact – good or bad, which I will email to you. As fire door inspections become more common we should be able to compile some data about what percentage of the existing doors have deficiencies, but that’s probably the closest we’re going to get to what you’re looking for.

Lori, have you seen any published data on the reliability of fire or smoke doors? I’m interested in the likelihood of failure of these measures.
