This photo of a hospital corridor door was sent by Hyun Myung Kang. I’m pretty sure this installation doesn’t comply with NFPA 80.

Should have used lead shields 🙂
Appears they used the wrong size anchors
It looks to be a repair of a repair. The screws also look incorrect. The thread looks like drywall fasteners. The heads don’t fit the countersink in the hinge
Hmmmmmmm…
Fire and plastic…..
Nuff said….
David,think you see what I saw. Drywall screws used (not proper size wood screw).
Chuck, I am not sure lead shield would have the holding power. I really do not know.
Being a corridor would a 20 min rating be a good assumption. If so, would steel hinge flller plate and UL continuous hinge be better (with minor door repair)?
I think Chuck was just kidding. 😉
And to answer your question…it’s hard to know what the rating is or should be, but there’s a point where it’s time to replace the door instead of trying to repair it. That point isn’t strictly defined, but the integrity of the fire resistance must be maintained.
I think they should use the old lifetime of installation warranty
