Hi, since we work with huges quantities I think that the minimum period that we can manage to keep the documents inside the chamber will be of 24hours, but I admit that I don’t see, from my experience, what can go wrong with these kind of time lapse, since I never see ink going sticky of paper becoming too fragile, for example.
Respirators can be a almost impossible mission when we try to impose them to people who’s been doing this from more than 20 years, however a good reliable information about it can make them possible in an optional way, as much it can be useful too in pushing authorities to buy a couple of aspiration chambers/bells -sorry but the adequate english term doesn’t comes to my mind now- to adequate the space.
Thanks a lot for your answer -as you see, its hard to get a feedback in this subject- and for any kind of info that you may get.
