Perhaps a material safety data sheet (MSDS)?

Many years ago, I remember getting a hazardous materials notice on Nautical Charts. Turns out that the ink in them contains Formaldehyde, at least it did at one time. Thus, when I dispose of Nautical Charts, I mark them as DO NOT RECYCLE. I have forgotten the name of the form that I received, but I know that I sent a message to Maps-L about it many years ago. This is probably something to consider when downsizing a map collection.
