Re: Chemistry and Physics in sealed part-used scrubbers

Unfortunately this is not a body of work we have done as diving is the only industry that leaves sodalime for any length of time without just throughing it away.

The answer is you need to use your experience and common sense as their are to many variables to take into account, time left, temp, RH, heat cold all can have some effect. I even heard of one guy who microwaved it, 'don't'!!

OK I am going to sign off before I put any more crazy ideas out there.

ARGH! No don't so that, tell us more?

I don't think I'm at all unique in what I've been doing. For example, if I'm doing a trip and I have say a 50mtr dive on day one and a 50mtrs dive on day 2, both will have 1 hour run times and my scrubber is nominally rated to 3hours. I will do both on the same fill with a 24hr gap then dispose of it.

I had assumed this was conservative from what I've seen and heard others do.

I can understand why you would say don't do it, because you have no test data, I'm more than alittle surprised this is the First time I've heard of this at all.
