I found a disintegrating plastic container of a mystery crystalline chemical in amongst the re-used plastic food containers of electronics spares in a cardboard box in the relative's shed. I only realized after reaching in to the container.
I believe that it was #thymol.
There was what was left of a non-specific hazard warning on the container, but the labelling was woefully inadequate to indicate the contents or the hazard and the lid had gone. Sold by a specialist supplier as an insecticide decades ago and them dumped part-used in a box by the relative. Alongside re-used plastic ice cream tubs still labelled for the ice cream.
Fortunately, I was wearing gloves. But now I've had to put those and all of my clothing into the wash, after rinsing myself down on site.
Leaving chemical boobytraps in what seems like a box of electronics odds and ends is not on.
