Ben when we say it is not safe I must clarify that we mean it is compromised and any further use of the material could have very umpredictable performance, splashing round in the shallows is probably OK but pushing it, taking it deep or expecting it to perform to manufacturers guidlines is not advisable.
Many thanks for the clarification.
The question is - what does this do to our calculation of scrubber life over multiple dives on a day or multiple day trip? I was taught what seems to be the common practice - keep track of the time on each dive (I add some padding for pre-breathing) and, as long as that time, plus the planned time for the coming dive are less than the manufacturer's recommended scrubber time, then you're good to go.
Do we need to calculate some kind of factor in to reduce the scrubber time with each repeated use of the same lime? Something like:
- First dive = 100% of mrst (manufacturer recommended scrubber time)
- Second dive = 75% of remaining mrst
- Third dive = 50% of remaining mrst
- etc
Does the time on each dive in the series affect the decay in performance, or is that simply a function of the fact that it has been used?
On the subject of longer storage - personally, I bin used scrubber if it is more than 14 days since I first used it, which seems in line with what others seem to do.
Cheers,
