Don't put certain tool handles in with artifacts...acetic acid and butyric acid

[Ted Langdell]

And since the handles are offgassing acetic acid, one probably would not want to store these in a film archive. It could start the film to have vinegar syndrome... 

Gary, perhaps you should put some molecular sieves into your plastic bags?

Or alternatively, store the tools in vented cans?

And it feels in the hand like a natural substance, something that is almost intangible, like a tool that is made by craftsmen, a characteristic that a polyethylene or polypropylene handle does not have. CAB also offers no splinters like the older wood handles. It also can be very clear. And when that plastic begins to degrade, it releases free acetic acid and butyric acid."
