Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) General. The employer shall comply with
the following requirements, which are applicable after each diving operation,
unless otherwise specified:
(b)
Precautions.
(1) After the completion of any
dive, the employer shall:
(A) Check the
physical condition of the diver;
(B) Instruct the diver to report any physical
problems or adverse physiological effects including symptoms of decompression
sickness;
(C) Advise the diver of
the location of a decompression chamber which is ready for use; and
(D) Alert the diver to the potential hazards
of flying after diving.
(2) For any dive outside the no-decompression
limits, deeper than 100 fsw or using mixed gas as a breathing mixture, the
employer shall instruct the diver to remain awake and in the vicinity of the
decompression chamber which is at the dive location for at least one hour after
the dive (including decompression or treatment as
appropriate).
(c)
Recompression Capability.
(1) A decompression
chamber capable of recompressing the diver at the surface to a minimum of 165
fsw (6 ATA) shall be available at the dive location for:
(A) Surface-supplied air-diving to depths
deeper than 100 fsw and shallower than 220 fsw;
(B) Mixed-gas diving shallower than 300 fsw;
or
(C) Diving outside the
no-decompression limits shallower than 300 fsw.
(2) A chamber capable of recompressing the
diver at the surface to the maximum depth of the dive shall be available at the
dive location for dives deeper than 300 fsw.
(3) The decompression chamber shall be:
(A) Dual-lock;
NOTE: Dual-lock is meant to include multi-lock
components if each is large enough to transfer personnel and supplies into and
out of the main compartment while it is pressurized. Medical locks do not meet
the intent of this requirement. A diving bell or manned deep diving system
capable of mating with a decompression chamber would meet this
requirement.
(B) Multiplace;
and
(C) Located within 5 minutes of
the dive location.
(4)
The decompression chamber shall be equipped with:
(A) A pressure gauge for each pressurized
compartment designed for human occupancy;
(B) A built-in-breathing-system with a
minimum of one mask per occupant;
(C) A two-way voice communication system
between occupants and a dive team member at the dive location;
(D) A viewport; and
(E) Illumination capability to light the
interior.
(5) Treatment
Table. Treatment gas appropriate to the diving mode, and sufficient gas to
conduct treatment shall be available at the dive location.
(6) A dive team member shall be available at
the dive location during and for at least one hour after the dive to operate
the decompression chamber (when required or provided).
