[PSUBS-MAILIST] FW: Escape with Steinke Hoods.

[hank pronk via Personal_Submersibles]

Hugh,
My understanding is, use regular tank air because your bottom time is so short.  One of the members posted an allowable time chart for flooding.  I think it is something like 1min 30 sec for 400 feet.
Does Com Sub have a flood valve, Gamma never did until I put one in.

  Hi Guys,My two
 Steinke hoods turned up. Made in USA 1982. Still in good
 condition.  I  have looked at the escape training
 video which was great. Questions.  It is obvious you
 need a fill hose for the initial fill at depth prior to
 opening the hatch.  i.e. if you are at 10 atmospheres
 depth then you need to fill it with 10 atmospheres (bar)
 pressurised air. 1.      
 How many of you are
 adding a Steinke fill hose with an Aro coupling for this
 purpose.  2.      
 Breathing this will
 give you narcosis.  So is it better to have 2 bottles
 of mixed gas for this purpose? One for 8-15 bar depth
 escapes and one for 16-25 bar depth escapes.  Air could
 be used up to 8 bar.3.      
 What are the mixes
 recommended for these depths to prevent narcosis as it could
 take 5 minutes to pressurise and escape. Chs 
 Hugh.
