Superglue...

This was a health and safety nightmare. Opening the churns of superglue, the fumes could easily knock you off your feet. Eventually they made a rule stating that pregnant women did not have to work on superglue as there were concerns regarding the fumes and the unborn babies. To avoid getting your fingers stuck together you would spray silicone on your hands and then cover them in glue and let it dry. This formed bizarre glue gloves, so that if your fingers did stick together you wouldn’t pull your skin off trying to part them.
