OVERVIEW
These courses are to provide the diver
with the skills and knowledge needed to minimize the risks of utilizing
helium-based tri-mix breathing gas mixes for dives to a maximum depth of
300 fsw (91 msw) requiring stage decompression and utilizing EANx mixtures
and/or oxygen during decompression. There are two levels, called Tri-Mix
Diver Level I and Tri-Mix Diver Level II.
Required manuals for this course are the
NAUI Trimix workbook and the
TDI Trimix Manual.
QUALIFICATIONS OF
GRADUATES
Upon successful completion of the Level I
course, graduates are considered competent to plan and execute technical
dives that require stage decompression and utilize helium-based tri-mix
breathing gas mixtures and EANx and/or oxygen for stage decompression
without direct supervision to depths not to exceed 225 fsw (69 msw)
provided the diving activities and the areas dived approximate those of
training. Level II graduates are considered competent to plan and execute
technical dives that require stage decompression and utilize helium-based
tri-mix breathing gas mixtures and EANx or oxygen for stage decompression
without direct supervision to depths not to exceed 300 fsw (91 msw)
provided the diving activities and the areas dived approximate those of
training.
