What are the 4 notes for the Navy chamber support levels?
NOTE 1: Based on space constraints at the site, the Commanding Officer may authorize extension of the surface interval to a maximum of 7 minutes
NOTE 2: A non-Navy chamber may be used if authorized in writing by the first Flag Officer (FO) in the chain of command, and must include a NAVSEA 00C hazard analysis.
NOTE 3: A non-Navy chamber may be used if it is evaluated utilizing the NAVSEA non-Navy recompression chamber check sheet, and authorized in writing by the Commanding Officer.
NOTE 4: During extreme circumstances when a chamber cannot be reached within 6 hours the Commanding Officer can give authorization to use the nearest approved recompression facility.
What are the 3 Navy recompression chamber support levels?
LEVEL 1: A U.S. Navy certified recompression chamber close enough to the dive-site to support surface decompression with a surface interval of 5 minutes. (NOTE 1,2)
LEVEL 2: A U.S. Navy certified recompression chamber accessible within one hour of the casualty (NOTE 2)
LEVEL 3: A U.S. Navy certified recompression chamber accessible within six
hours of the casualty (NOTE 3,4)

165 fsw (6 atmospheres absolute)
How many chamber occupants can you treat with a RCF series 6500 and 5000?
RCF Series 6500: 12 occupants
RCF Series 5000: 7 occupants
