I did check 99 and quoted it below so I get other interpretation. I only referenced 21 in 13 because it was the only reference to hyperbaric chambers and that was for A type, I have B type so I was asking since I have B type would the room be protected per light hazard as shown in 5.2 "hospitals" of NFPA 13

You might want to see what NFPA 99 states to see if it offers more information. John John August Denhardt, P.E.

This room has two single hyperbaric chambers. According to NFPA 99 20.1.5.2, these would be Class B chambers (correct me if I'm wrong). Per 20.2.6 Class B & C chambers do not require a fire suppression system. Per 20.2.1.3 "The room or rooms housing Class B & Class C chambers shall be afforded sprinkler protection in accordance with 20.2.1.2." (That's the first time I have seen it put like that), 20.1.2 "A hydraulically calculated automatic wet pipe sprinkler system meeting the requirements of NFPA 13 shall be installed in the room housing a Class A chamber and in any ancillary equipment rooms." So if I interpret that correctly we need a wet type system in the room only. Now 13 only calls out A type chambers (21.19) so would the system need to be light hazard per 5.2 Hospitals? Or is there other direction for this room I'm missing? Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.
