Samsung is 100% correct. Here's an example:
A past employer used barrels that had a residue of dried shoe glue on the bottom. The glue was inert in its dried state, and posed no health risks (unless a person ate it in quantity). However, the glue had been made with diisocyanates that would produce a potentially lethal cyanide gas when burning. When I pointed this out we started using clean barrels.
