Rush Escape- if a suit is not available or the situation has changed so it requires escape to be expedited or there was no time for the DSRV or Controlled Ascent, hence the name 'rush'. Controlled Ascent- Personnel are suited up and proceed to escape in an orderly manner through the tower with the skirt lowered. DSRV/LR5 - transfer of many people at once with the ability to adjust pressure as necessary to prevent or reduce the likelihood of decompression sickness. If you were doing a rush escape you might feel it took a little longerĭon't forget the options and their order of preference Yes, it would sure feel like a long time, especially if you had begun your ascent an air filled suit. The exact time depends on the depth they need to start breathing out and the rate of ascent. If at any point during the ascent the persons mouth is covered by water they are trained to breath out all the way to the surface to release the pressure inside their lungs with the aim of getting safely to the surface. This increases survivability by a large factor When the person reaches the surface the pressure in the suit (and the persons lungs) should be the same as the air around them or very close to it. This has the effect of equalising the pressure inside the suit (and the persons lungs) to the surrounding sea pressure. The open bottom of the hood releases air as the person and the suit is under less pressure and the air expands and the person inside it breaths normally. When the suit has enough pressurised air in it to overcome sea pressure and the person will begin ascending to the surface as they are now positively buoyant. The person wearing the suit and in the flooded escape tower will connect to a fitting inside the tower. The escape suits you mention have la hood with an open bottom well below their shoulders and they are filled with air from a built in charging coupling usually at the wrist. There are no pressurised rubber suits that can explode. USS Razorback - SS 394 - Little Rock AR.Veteran's Crisis Lineġ-80 or text "start" to 741-741 Museum Submarines
