Fire Rated Doors and spec plates

[nemptygarden]

The hospital I work for was constructed in 1968 and none of the bedroom doors or corridor doors have fire rated name plates indicating burn time. Are plates available for these doors (13/4" solid core)?

Nep,

Check the top of the door, back in the old days they sometimes put the label on the top of the door. If not, u will need to replace the door to receive the rating.

based on the building age - what if the door did not require a fire resistive rating?

I think it didn't. (What a way to conjugate a sentence)

stookeyfpe, I can not conjugate a sentence of that perportion. There is not plate at the top of the doors. During JCAHO, I might be asked to back up the assertation that the doors did not require a fire resistive rating, point me in the right direction. Also, being that the doors are 13/4" would that not make them 20 minute rated?

Their are plenty of methods to calculate fire-resistance using a equivalent thickness method. The NFPA Fire Protection Handbook and the SFPE Handbook of Fire Protection Engineering both have detailed chapters addressing the subject.

Off the top of my head, I would say your doors have at least 20 minutes of fire-resistance based on ASTM E-119 fire test performance requirements. I can't confirm it without performing some calculations and reviewing the previously mentioned references.

some ahj's excepted solid wood unrated door as equal to a 20 minute door

JCAHO... u better have a letter from a PE with the calculations to get them to accept, I think usually does not work with JCAHO
