Normal max limits for mk 16 on n202 and he02
150 and 190
300 and 300
How many repets if you have done 1 D dive
3 no d dives or 1 d dive
How many repets after dive >200fsw
No repets
When is level one chamber required
All dives deeper than 200fsw
D stops deeper than 20fsw
Total D time exceeds 30 min
All exceptional exposure
Level two chamber
Dives 200 fsw and shallower with stop at 20 but total stop time less than 30 min
Level 3 chamber
All no d dives under 200
Line pulls for mk16/ebs
1 7 2-3 3-2 2-1 5
1- arrived at lazy shot 7- found/complete work 2-3 dcs symptons 3-2 breathing from EBS 2-1 unshackle from lazy shot 5 exceeding planned depth of dive. 1 add pull for every five feet
When do you abort if rig has not transitioned
40fsw
Can you repet with a dil change
No procedures for repet dives with a diligent change
Max dive times
In 1.3 mode
4 hours a day
16 hours a week
Cause of hypercapnia build up
Failure of scrubber
Excessive work rate
Treat hypercapnia
Stop work ascend increase ventilation.
Asymptomatic omitted D
No stop omitted
No d status
Chamber in 60-
Observe every for 1 hr
No chamber-
Observe for one hour
Asymptomatic omitted D
20ft stop omitted d stop required
SI 1 min, 1-5 min, >5min
<1min SI- chamber in 60 return to 20fsw and add 1 min.
1-5 min- return to 20ft stop mult stop time by 1.5
> 5min- chamber in 60- TT6, no chamber return mult stop by 1.5
Asymptomatic omitted D
Stop deeper than 20fsw omitted
SI 0-5, >5, any
D stop less than 30, greater than 30
D stop less than 30, SI 0-5 min chamber in 60- TT 5
No chamber return to deepest stop and mult all stops by 1.5
Dstop > 30 min - TT6, no chamber? Return and mult stops by 1.5
Procedures for DCS in water
Descend to depth of relief in 10fsw increments but no deeper than 2 increments.
New profile with stops mult by 1.5
Ascend and lengthen stops as needed
If asymptomatic TT5
Delays in ascent
Greater than 1 minute deeper than 50fsw- round up and add to bottom time
Great than 1 minute shallower than 50fsw-
Round up and add to first d stop.
Delays less than 1min ignore
Diving at altitude
1000ft max altitude for diving mk 16
What is a FAR
Failure analysis report for mk 16 component failures or inadequacies. Submitted electronically to pms EOD website.
REC
Re-entry control
Process for working on a certified system. Pneumatics system.
What percentage of 02 can cause hypoxia syptoms
16% or .16 ata
Hypoxia beyond helpless ness?
.11 and unconscious at .1… death below these
Primary bats below what reading on secondary must be discarded
- 2 volts for modernized
- .95 for legacy electronics
O2 sensor criteria
22-28 millivotlts
Allow sensors to stabilize for 60 minutes after opening
