Divers shall use the latest available U.S. Navy Standard Air Decompression Tables and other appropriate U.S. Navy diving tables for decompressions and repetitive dive decompressions.
A recompression chamber that meets the requirements of the most recent edition of the U.S. Navy Diving Manual shall be kept at the diving site whenever planned dives will exceed the "no decompression" limits as specified by the U.S. Navy Standard Air Decompression Tables.
Whenever a recompression chamber is required, a qualified person shall be immediately available to operate the chamber.
An adequate approved method of supplying air shall be readily available for the immediate operation of the chamber.
