Just out of curiosity I was Googling for distilled water suppliers to see how much it cost and came up with this extraordinary document.

's their safety data sheet for distilled water. I had no idea how f
***ing dangerous that stuff is. Some snippets.
Do not discharge into drains or rivers. Contain the spillage using bunding. Clean-up procedures: Absorb into dry earth or sand. Transfer to a closable, labelled salvage container for disposal by an appropriate method.
Hand protection: Protective gloves. Eye protection: Safety glasses. Ensure eye bath is to hand. Skin protection: Protective clothing.
Stability: Stable under normal conditions. Conditions to avoid: Heat. Materials to avoid: Strong oxidising agents. Strong acids. Haz. decomp. products: In combustion emits toxic fumes.
I'm wondering what you'd want in the eye bath to wash your eyes out with if they got splashed with distilled water? Ummmm - more water?
Handy to know it emits toxic fumes if you put it on a fire though. I'd better phone up my local fire brigade and see if they're aware they've been using the wrong stuff all these years.
Oh, it's also obviously no use for the OP if he wants to put it in batteries if one of the materials to avoid with it is strong acids.
