One more thing about ratings of patient bedroom doors

Regarding my post yesterday about rated doors, perhaps a little clarification is in order. My note was aimed at exiting healthcare occupancies under Chapter 19 of the Life Safety Code.

In looking through the code for other occupancies for which this door requirement might be applicable in sleeping areas (e.g., dormitory/hotel, residential board and care), I could find no other mention.

Thanks to those who asked me about this.

Rating of patient bedroom doors

A colleague recently asked me whether patient bedroom doors should be 20-minute-rated-and the answer is yes, they should. But there are some qualifications on that answer, depending on sprinkler protection.

Under paragraph 19.3.6.3.1, the 2000 Life Safety Code requires doors protecting corridor openings to resist the passage of smoke and be constructed of the following:

  • 1 3/4-in. thick, solid-bonded core wood
  • Material that resists fire for at least 20 minutes

There are two exceptions to 19.3.6.3.1, though:

  • Doors to toilet rooms, bathrooms, shower rooms, sink closets, and similar auxiliary spaces that don’t contain flammable or combustible materials don’t need to meet 19.3.6.3.1’s provisions
  • In smoke compartments protected by sprinklers, the door construction requirements of 19.3.6.3.1 aren’t mandatory, but the doors must resist the passage of smoke
