In a recent Q&A on the FacilityCare website, consultant Brad Keyes answered a question about linen chute doors.
Q: Do linen chute doors in an existing structure have to be rated if the room that houses the linen chute is protected by a two-hour wall and the door for this room is rated at 90 minutes?
A: Yes they do. There is no exception in NFPA 82 for the chute doors in a vertical chute that opens into a room that has the same fire-resistive rating as the shaft.
