| The DCIEM did a study into this for the Canadian Forces, you should be able to download it from their website. Basically, naval divers were using the RBs intermittently and when they were needed it was usually in a hurry so they wanted to keep them prepped and ready. The study looked at the feasibility and safety of it.
IIRC Canadian Forces rules based on the results are seven days storage allowed between dives (either unused or partially used scrubber) without maintenance as long as the unit had maintained positive pressure without leaking. From memory they were using Carlton SIVAs. Obviously there would have to be enough life left in the scrubber to make it worthwhile. |
