Cyanide salt solution by themselves are not dangerous
Ah, that's good to know .....
Many years ago, with a different work hat on, a colleague and myself were involved in moving all the IT when one of our remote offices (part of another company ours had acquired) to a new location. My colleague was at the old site busy packing stuff up, and I was at the new site unpacking it as it arrived - and getting the networking stuff setup in preparation.
My colleague left the other site when he'd finished, and we heard that had he been another 5 minutes then he'd have been stuck there for some time. Someone had found a large bottle labelled Cyanide in the cellar of a house and the Police had locked down the area while the nasties clean up squad removed it.
Biting the hand that feeds IT
