Fire-Rated Doors in Fire-Rated Barriers?

Q: If the health care facility is fully sprinklered do doors in a corridor, where the walls are fire rated, do the doors have to be fire rated? I read in NFPA 101 that they do not….

A: Where do you read that…? I would like to know what you’re reading to be able to provide you with a better answer.

Generally speaking, where you have a fire-rated barrier, you usually need to have fire-rated doors in openings in the fire-rated barriers. But there are some exceptions:

  • Fire-rated barriers that separate an atrium from the rest of the facility are not required to have fire-rated doors.
  • Corridor walls in existing healthcare occupancies located in a smoke compartment that is not fully sprinklered, are required to be 30-minute fire-rated and the corridor doors are permitted to be non-fire-rated, but must limit the passage of smoke.
  • Some building codes that require fire-rated corridor walls do not require fire-rated doors in the openings. But this is not a LSC issue.
  • Smoke barriers that separate smoke compartments are required to be rated (1-hour for new construction) but doors in smoke barriers are not required to be fire-rated.
