NFPA 99 Chapter 20 (188.8.131.52.3) states that a source of breathable gas allowing unrestricted mobility shall be available outside a Class A or B chamber for use by personnel in the event that the air in the vicinity of the chamber is fouled by smoke or other combustion products of fire.
This section of the NFPA 99 speaks to a situation where if there was a fire in the room where your chambers are located (and assuming the chambers have patients in them), how will you deal with the smoke in the room while trying to decompress 2 or more patients and evacuate them without putting yourself and other staff at risk of being overcome by the smoke? An excerpt from Ken Capek’s article in the RT Focus Journal states “This standard can be met by having a self-contained breathing apparatus (SCBA) or “smoke hood” with filtration system. The specific type of hood you purchase should be based on the time it takes to actually evacuate a patient. The evacuation duration time can only be known by performing an evacuation drill in your facility. Practice using the hood, but do not remove the airtight filter plugs for the drill or they will need to be replaced.”
For those that do not have smoke masks available in their center yet I have done a little research and found a couple of options. These products I have linked to below meet the requirements of NFPA 99 Chapter 20. The Xcaper Enterprise Smoke Mask Kit is only good for a minimum of 15 minutes.
The Dräger Smoke Hood Kit is also good for a minimum of 15 minutes as well.
