There’s an exception in the Health Care chapters of NFPA 101 that I’ve always wondered about. It’s in the chapters regarding New & Existing Health Care Occupancies (18 & 19), in the section about corridors:
2009 Edition of NFPA 101:
22.214.171.124.12*/126.96.36.199.12* Nonrated, factory- or field-applied protective plates, unlimited in height***, shall be permitted.
A.188.8.131.52.12/A.184.108.40.206.12 It is not the intent of 220.127.116.11.12 to prohibit the application of push plates, hardware, or other attachments on corridor doors in health care occupancies.
***Please note that prior to the 2006 edition of NFPA 101, these plates were limited to 48″ high.
Somewhere along the line I was told that this exception meant that fire-rated corridor doors in health care occupancies did not have the limitation of 16″ on protection plate height. A couple of weeks ago a local hospital asked me for help in getting documentation of the cans and can’ts of armor plates on wood fire-rated doors, so the first thing I checked into was this exception. I emailed NFPA (membership has its privileges), and received a very complete and concise answer:
“The provisions of 18/19.3.6 address corridor doors that are not otherwise regulated by some other code provision (where more than one set of requirements apply, the more/most stringent must be applied). For example, doors from corridors to exit stair enclosures do not get to use the exemption of 18.104.22.168.12 because such doors must be fire-rated assemblies per 22.214.171.124 and Table 126.96.36.199 and, thus, in compliance with NFPA 80. Similarly, doors from corridors to hazardous contents rooms do not get to use the exemption of 188.8.131.52.12 because such doors must be fire-rated assemblies per 18.3.2 and Section 8.7 and, thus, in compliance with NFPA 80. In other words, the provisions of 18/19.3.6 speak to patient sleeping room doors, patient treatment room doors, office doors, staff area doors and similar spaces, but not to exit doors, smoke barrier doors, vertical opening enclosure doors, and hazardous area doors.”

In other words, fire-rated doors in health care occupancies must comply with the protection plate requirements of NFPA 80 – no special exception. However…I’ve been looking into the listings of 5 different wood door manufacturers and it looks like they all allow plates higher than 16″. I’ll post that information as soon as it’s all confirmed, so stay tuned!
