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
C02 canister duration
14 days if double bagged and sealed
30 days if in an opened can
24 hrs if in a mk 16
Bottle 02 duration and consumption
Average consumption rate of 1.4L/min bottle duration is 5 hrs
02 add valve
Adds at 5 SLM
Pony bottles
21cuft at 3000psi
Charged at 100-200
Regulators bring down to 230-270
Initial set ups when?
6 months, prior to a mission, after any sensor is replaced or repositioned, the center section, PEA, or secondary is replaced. After start up pms
Lo my and hydro
Every 5 years
