Chapter 9: KISS CCR Skills

1. Chapter 9: KISS CCR Skills • Skills • Rules to LIVE by

2. Chapter 9: KISS CCR Skills • Pre-dive prep • Assemble KISS CCR • Unit Verification Checks • Analyze, gas flow check, positive/negative pressure check, overpressure relief valve check, ADV check, HP check, calibration/PO2 display,O2 manual addition/ passive addition • Pre-dive checks

3. Chapter 9: KISS CCR Skills • Pre-breath loop just before entry • In water buddy / leak checks • At surface bubble check, and again at 20 fsw (6 msw)

4. Chapter 9: KISS CCR Skills • Descents/ascents buoyancy/PO2 control • Controlled descent maintaining PO2 • Maintain proper buoyancy and trim • On ascent vent BCD, dry suit, and loop (nose) and maintain PO2, saw tooth swims • Oral BCD inflation • At surface and UW

5. Chapter 9: KISS CCR Skills • Loss of BCD buoyancy control • Use suit, and try lift bag buoyancy control • OC bailout and bailout on separate system • OC by switching DSV, and turn off DSV and go to separate OC (turn O2 off!!)

6. Chapter 9: KISS CCR Skills • SCR mode • Breath 1-2 on loop, breath 3-5 vented out loop through nose (for 15 min) • Hyperoxia / hypoxia drills • Switch to OC and determine cause of problem • Hypercapnia drills • Switch to OC and bail out • Flood drills • Switch to OC, maintain buoyancy • Demonstrate flood position

7. Chapter 9: KISS CCR Skills • Stuck open O2 controller • Hold O2 open • Turn O2 cylinder on and off to control • Manually control diluent addition • Blow out through nose to force diluent addition

8. Chapter 9: KISS CCR Skills • Lift bag deployment / decompression drills • Deploy for surface monitoring / help • Buddy out of air drills

9. Chapter 9: KISS CCR Skills • Difficulty breathing • Switch to OC, assume system flood • PO2 display issues • Flush system, work out “flush PO2 ” and ensure sensor are correct • Failure to maintain set point (DSC avoidance drills) • Assume set point failure, complete ascent with bail out plan, and without bail out plan • Stage doff / don • Maintaining correct trim / buoyancy

10. Chapter 9: KISS CCR Skills • Dead space drill: • Lye perfectly horizontal to experience increased WOB on exhale • Counter lung size check • Oxygen rebreather mode • Flip onto back to experience “chipmunk” cheeks

11. Chapter 9: KISS CCR Skills • Practice locating and operating • DSV on off • O2 on off • Diluent on off • O2 consumption drill • Turn O2 off, purge line • Once steady at 1.3 atm • Swim until 1.1 atm • Note time

12. Chapter 9: KISS CCR Skills • Something appears wrong (IT IS!!!) • Deal with it • It is always a good idea to go to OC to clear your head and then decide on course of action • Live to dive another day • Complacency Kills • Murphy is watching

13. Chapter 9: KISS CCR RULES TO LIVE BY • Always know PO2 • Always close DSV before removing from mouth • Don’t dive with gas supply cylinders off • Complete at least 30 hours of benign dives with KISS CCR above 100 fsw (30 msw) on air as a diluent before moving on to more training and more challenging dives • Must be able to multitask • Always dive with a buddy

14. Chapter 9: KISS CCR RULES TO LIVE BY • Always think ahead and have a plan • Don’t become over confident before your time and training • No one person has all the answers, keep an open mind and ear, • keep on learning and living

15. Chapter 9: KISS CCR RULES TO LIVE BY • Pre-dive checks are essential, ALWAYS • Always know MURPHY is watching and will visit at • the first sign of complacency • NEVER GIVE UP
