INSPIRATION CCR TRIMIX DIVER
A. Purpose
1. This Program is designed to train divers in the safer use and
technology of the Inspiration CCR for dives with extended decompression,
using helium-based gas mixtures.
B. Prerequisite
1. Must be qualified as a Rebreather Diver, and either be already
qualified as a Normoxic Trimix Diver or Trimix Diver, or be taking the
Technical Diver and Trimix Diver Programs concurrently using the Inspiration
CCR.
2. Must provide proof of a minimum of 200 dives, and at least 50
logged hours of dive time on the Inspiration CCR, with at least 25 dives
that included required decompression stops.
3. Must be a minimum of 21 years of age.
C. Texts
1. Rebreather Diver Student Manual and Workbook
2. Inspiration Owners Manual.
Additionally, if Technical and Trimix Programs are taken concurrently:
3. Technical Workbook.
4. Trimix Workbook.
D. Program Content
1. Complete all academic portions of the Rebreather Diver
Student Manual and Workbook and the Inspiration Owners Manual.
2. Complete a written exam specific to the Inspiration CCR with a
minimum score of 80%.
3. This Program must include a confined water session prior to a
minimum of 4 dives using the Inspiration CCR with helium-based gas mixtures.
All of the dives must be deeper than 165 fsw (50 msw).
4. If Technical Diver and Trimix are taken on the Inspiration 8 dives
must be completed with 4 deeper than 165 fsw (50 msw).
E. Equipment Requirements
1. Must own an Inspiration CCR.
F. Program Limits
1. Adhere to all Program Limits specified in the Technical
Rebreather Diver Program.
2. No dives may be conducted to depths greater than 260 fsw (79 msw).
3. The PO2 set-point may not be set higher than 1.30 ATA
during the working portion of the dives, nor higher than 1.40 ATA during the
decompression portion of the dives.
4. If an oxygen second stage is fitted to the rebreather, the second
stage must be protected by a regulator guard.
G. Water Skills Development
1. A confined water session demonstrating all skills
must be completed to the instructor’s satisfaction prior to conducting any
open water dives.
2. A confined water session must be completed before conducting any OW
dives.
3. Become familiar with breathing controls.
4. Shut off and turn on gas supplies.
5. Perform loss of gas drill.
6. Simulate bailout procedures.
7. Perform electronics failure drills.
8. Perform broken hoses drill.
9. Perform flooded canister drill.
10. Perform Three H’s emergency drills.
11. Simulate counterlung rip.
12. Practice use of BCD.
13. Hover with minimum of motion at a specified depth (combination of
confined water drills and safety stops in OW).
14. Clean unit to avoid contamination and spreading of disease.
15. Practice system monitoring.
16. Perform leak test.
17. Pack absorbent canister.
18. Swim 60 feet (18 meters) without breathing, and exhaling slowly, and
then perform bailout procedure.
19. Practice switching to and handling of stage for both diluent and
oxygen if applicable.
20. Perform all skills and procedures specified by the manufacturer of
unit training is performed on.
21. Complete all Waterskills listed under the Rebreather Diver Standards
in Sport Diver Programs.
The Below skills are for divers not previously qualified as Trimix Divers
22. 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. After taking 3 breaths at rest, continue swimming at a normal
rate while sharing gas for at least 2 minutes.
23. While swimming, demonstrate efficient switch to stage cylinder
regulators.
24. 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.
25. Prior to dives, students must demonstrate Gas Management.
26. Remove and replace stage cylinders both at rest and while swimming.
27. Deploy and use a lift bag or up line at least once in OW.
28. 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 1½ minutes,
students in continuous webbing who exceed this time must add a quick release
to their harness). Repeat until proficient.
29. Complete all Waterskills listed under the Rebreather Diver Standards
in Sport Diver Programs. |
