look at the trimix standards item 10 and item 5 in the technical diver under
watermanship

I posted the trimix diver first then thetechnical diver

Here is the international standard

I have forwarded this to Afonso , all IANTD standards are the exact same
except where law requires a difference. Under Trimix look at item 10.

Trimix Diver
A. Purpose
1. This Program is designed for those individuals already involved in deep
diving activities, but is not intended to be used as an enticement to divers
who are content to remain in normal Sport or EANx diving limits.
2. Trimix affords a safer means for deep-water exploration for divers who
must dive deep or perform with a clear head at the intermediate depths. The
IANTD Trimix Diver Program establishes the need to be
self-sufficient/reliant. This diver will be qualified to dive using Trimix
to a maximum depth of 260 fsw (79 msw).
B. Prerequisites
1. Must be qualified as an IANTD Technical Diver or Technical Cave Diver or
Technical Wreck Diver or Normoxic Trimix Diver or equivalent.
2. Must provide proof of a minimum of 200 logged dives, of which at least 25
were to depths between 140 fsw (39 msw) and 200 fsw (60 msw)..
3. Must be a minimum of 18 years of age.
OR, if being accepted in the Program based on equivalent experience:
4. Must provide proof of a minimum of 250 logged dives, of which at least 75
were deeper than 100 fsw (30 msw), and at least 25 between depths of 140 fsw
(39 msw) and 170 fsw (51 msw).
5. Must be a minimum of 18 years of age.
C. Texts
1. IANTD Trimix Student Workbook, or equivalent text(s) approved in writing
by the Board of Directors (written approval will be issued by IAND,
Inc./IANTD World Headquarters).
2. IANTD Technical Diving Encyclopedia, or equivalent text(s) approved in
writing by the Board of Directors (written approval will be issued by IAND,
Inc./IANTD World Headquarters).
D. Program Content
1. Perform two skills-training dives following completion of the confined
water session(s) in which two stage cylinders are used, to a depth between
60 fsw (18 msw) and 170 fsw (51 msw). These dives may be on air or Trimix
provided the depths are acceptable for the gas used, and two gas switches
are practiced during ascent. Divers progressing from Normoxic Trimix to
Trimix may not do dives on air deeper than 130 fsw (39 msw)
2. This Program must include a minimum of 240 minutes of open-water run
time, completed within four trimix dives to depths between 160 fsw (48 msw)
and 260 fsw (79 msw). All depths must be worked up to incrementally with no
increase greater than 40 fsw (12 msw) from one dive to the next (the first
dive in the course on mix must not be more than 33 fsw (10 msw) deeper than
the student's previous experience in deep diving).
3. All dives must include two gas switches.
4. Divers entering the Program on equivalent experience must complete the
above requirements plus make two additional training (for a total of six
training dives) dives using two stage cylinders. These two additional dives
may be on air , EANx or Trimix at the instructor's discretion.
5. If the course is a combined course (e.g., Technical Diver and Trimix
Diver), the Program must include a minimum of 540 minutes of open-water run
time completed within at least 10 dives.
6. To complete the course within the minimum specified dives students must
have an average of 8 points (out of 10) on he watermanship evaluations. With
2 or more additional dives the student may graduate from the course with an
overall average score of 6 points
E. Equipment Requirements
1. Fulfill all Equipment Requirements as specified in the general Technical
Diver Programs overview.
F. Program Limits
1. There may be no more than 4 students per Instructor on any dives, and no
more than 3 students per Instructor on dives conducted to depths greater
than 220 fsw (66 msw). The ratio for deeper dives may be increased to 4
students with an assisting IANTD Technical Instructor who is also a
qualified IANTD Trimix Diver or a Trimix supervisor.
2. No dives may be conducted to depths greater than 260 fsw (79 msw). Trimix
dives may not be made to a depth less than 160 fsw (48 msw).
3. Equivalent Narcosis Depth (END) may not exceed 130 fsw (39 msw).
4. Surface oxygen must be available for use in the event of Decompression
Illness (DCI).
5. All dives must be performed as a single dive team.
6. All appropriate safety or required decompression stops must be performed.
G. Waterskills Development
1. A confined water session must be completed before conducting any OW
dives.
2. Two divers approximately 60 feet (18 meters) apart, locate each other
while simulating an out of air situation (without breathing, and exhaling
slowly) and begin gas sharing via long hose. After taking 3 breaths at rest,
continue swimming at a normal rate while sharing gas for at least 2 minutes.
3. Simulate gas failure with valve shutdowns for both primary and secondary
regulators. The entire drill must be completed in less than 1 minute. This
drill should be completed at least once each dive, with a buddy acting as a
safety diver, then switch roles. Upon completion of skill, verify both
primary tanks are turned back on.
4. While swimming, demonstrate efficient switch to stage cylinder
regulators.
5. Following a means of reference (pool wall, guide line, ship railing,
etc.) with eyes closed, remove stage cylinders and swim a distance of at
least 15 feet (4.6 meters). Reverse direction, return to stage cylinders and
replace them on correct sides, identifying each cylinder by feel.
6. Prior to dives, students must use IANTD Gas Management Charts to match
gas turn points.
7. Remove and replace stage cylinders both at rest and while swimming.
8. Deploy and use a lift bag or up line at least once in OW.
9. Remove and replace equipment during confined water training (doubles and
stage[s]), first on the surface, then on the bottom, in less than 2 minutes.
10. Simulate a rescue of a diver, tow the diver on the surface for a
distance of at least 40 feet (12 meters) while simulating mouth to mouth
resuscitation. Go through EMS procedures and remove equipment from victim in
the water (equipment removal must be accomplished in less than 1 ½ minutes,
students in continuous webbing who exceed this time must add a quick release
to their harness). Repeat until proficient.

Technical Diver
A. Purpose
1. This Program is designed to train divers to conduct dives to depths
between 100 fsw (30 msw) and 170 fsw (51 msw) using custom blend breathing
gas mixtures; and to provide greater understanding of custom blend breathing
gas mixtures, a complete knowledge of the limits of any EANx mixture, and
the use of EANx and oxygen for decompression.
B. Prerequisites
1. Must be qualified as an IANTD Advanced EANx diver.
2. Must provide proof of a minimum of 100 logged dives, of which at least 30
were deeper than 90 fsw (27 msw).
3. Must be a minimum of 18 years of age.
OR, if being accepted in the Program based on equivalent experience:
4.  Must be a qualified IANTD or equivalent Nitrox Diver.
5. Must provide proof of a minimum of 150 logged dives, of which at least 50
were deeper than 90 fsw (27 msw).
6. Must be a minimum of 18 years of age.
C. Texts
1. IANTD Technical Student Workbook, or equivalent text(s) approved in
writing by the Board of Directors (written approval will be issued by IAND,
Inc./IANTD World Headquarters).
2. IANTD Technical Diving Encyclopedia or equivalent text(s) approved in
writing by the Board of Directors (written approval will be issued by IAND,
Inc./IANTD World Headquarters).
D. Program Content
1. All lectures and theory in the Technical Student Workbook up to the
section on normoxic trimix and materials in the Technical Diving
Encyclopedia.
2. This Program must include a minimum of 300 minutes of open-water run time
completed within at least 6 dives.
3. Two of the dives must be to depths between 130 fsw (39 msw) and 170 fsw
(51 msw). For students who need additional training dives, the remaining two
dives may be in any depth between 40 fsw (12 msw) and 170 fsw (51 msw).
4. At the Instructor's discretion and as specified in the Standards,
previous dive experience may be credited. The maximum credited dives from
other Technical Programs (e.g., Cave, IANTD Wreck, etc.) and/or other dive
experience is 4 dives, at least two of which must have been deeper than 130
fsw (39 msw). Even with maximum crediting of previous dive experience, this
program must include a minimum of 4 dives, and 240 minutes of run time.
5. To complete the course within the minimum specified dives, students must
have an average of 8 points (out of 10) on the watermanship evaluations.
With 2 or more additional dives, the student may graduate from the course
with an overall average score of 6 points.
E. Equipment Requirements
1. Fulfill all Equipment Requirements as specified in the general Technical
Diver Programs overview.
F. Program Limits
1. There may be no more than 4 students per Instructor. This ratio may be
increased by 2 students (for a maximum of 6 students) with an assisting
IANTD Technical Diver Supervisor or Advanced EANx Instructor who is also
qualified as a IANTD Technical Diver. The Instructor must be in control at
all times.
2. No dives may be conducted to depths greater than 170 fsw (51 msw).
3. Oxygen partial pressure may not exceed 1.40 during the working portion of
the dives, nor exceed 1.60 ATA during the decompression portion of the
dives.
4. All appropriate safety or required decompression stops must be performed.
5. Decompression stops must be made using oxygen or EANx.
G. Waterskills Development
1. A confined water session must be completed before conducting any OW
dives.
2. Swim with full underwater equipment required in Program for at least 5
minutes.
3. Swim in a simulated out-of-air situation (without breathing, and exhaling
slowly) for a distance of at least 60 feet (18 meters) with full gear, then
commence breathing. Repeat previous drill with 2 divers swimming
side-by-side, but have one diver hand-off the long-hose second-stage
regulator to the other diver and commence gas sharing. After remaining at
rest for 3 breaths, continue swimming at an average pace for at least 10
minutes.
4. Remove and replace equipment during confined water training (doubles and
stage[s]), first on the surface, then on the bottom, in less than 2 minutes.
5. Remove the harness and cylinders from a simulated-unconsciousness  diver
in less than 1 ½ minutes. (Student s who exceed the time limit on this skill
must have a quick-release added to their harness).
6. Divers using a quick-release on their harness or backpack must, in
confined water, swim the system while the instructor disconnects the
quick-release to simulate a failure. The student is to swim the system
demonstrating control of buoyancy and body positioning with the quick
disconnected for sufficient duration to satisfy the instructor that the
student is capable of managing.
7. Demonstrate an ability to respond to a single-bladder BCD failure by the
two methods listed below. (Students using gear configurations that prevent
accomplishment of these two skills will be required to wear a redundant BCD.
Students who already have a redundant BCD or dry suit may use one of these
alternates after attempting perform the methods without the use of the
alternative.)
a. Completely deflate BCD and swim while maintaining buoyancy control for at
least two minutes.
b. Completely deflate BCD, ascend safely to the surface, and remain afloat
for at least 3 minutes.
? NOTE: If at any time the student starts to over-exert, or if it is obvious
that the skill cannot be accomplished, the instructor is to ensure that the
BCD is inflated.
8. In confined water, have a student lose buoyancy by deflation of the BCD
and then attempt to utilize a lift bag or other secondary buoyant device as
a BCD.
? NOTE: This skill is to demonstrate how effective these devices are and to
reinforce that even if not suitable for a redundant BCD they still provide
an option for self rescue in an emergency situation.
9. Two divers approximately 60 feet (18 meters) apart, with blacked-out
masks or eyes closed, and while simulating an out of air situation (without
breathing, and exhaling slowly), locate each other (using side of pool, rail
on wreck, guide line, etc. for orientation) and begin gas sharing via long
hose. After taking 3 breaths at rest, continue swimming while sharing gas
for at least 3 minutes. This drill may be accomplished by having one student
swim 30 feet (9 meters) to donor, and repeat for other diver.
10. While two divers are swimming side-by-side, the Instructor signals one
to remain stationary while the other continues swimming for at least 3 more
kicks. The stationary diver then simulates an out-of gas situation by
swimming (without breathing, and exhaling slowly) to the other diver and
commences gas sharing for at least 2 minutes. This skill may be substituted
by the instructor starting the drill at some time when the students are at
apart from each other by a comparable distance as would be achieved by 3
kicks.
11. Simulate gas failure with valve shutdowns for both primary and secondary
regulators. The entire drill must be completed in less than 1 minute.
12. Close eyes, remove and replace stage cylinder, make regulator switch to
stage cylinder, then switch back to primary gas supply.
13. Gas shutdown at least once per dive. (It is not necessary to remove
mouthpiece.)
14. Remove and replace stage cylinder on all dives with as little buoyancy
change as possible.
15. Demonstrate use of a safety reel and deploy a lift bag while maintaining
a stable depth.
16. Demonstrate good dive technique and swimming (SCUBA) abilities combined
with correct buoyancy control.
17. Determine RMV and demonstrate ability to calculate

Dear Mr. Tom Mount,

I really appreciate your concerns and the quick response.

However, in the IANTD Brazil Standards and Procedures Manual, (
Technical Diver and Trimix Diver ), the skill requires :

"Students that can not remove their own equipment at least 1 1/2 minute,
with backplate, will be required the use of quick releases in the
Harness"

I agree about the EMS procedures, but there is nothing mentioned about
"Simulate a rescue of a diver, tow the diver on the surface for a
 distance of at least 40 feet (12 meters) while simulating mouth to
mouth resuscitation".

Please check it in the Portuguese Version - Revision : November 1999,
pages : 62 and 74.
