The one I heard second hand was from a Dutch factory when they first insisted on safty boots. Some workers complained that they always wore Clogs, and they thought they were safer, so after some argument it was decided to run a test, the boots were supposed to withstand a weight dropped from a certain hight, so that was the standard. The weight was dropped on the Clogs, they passed, then the boots, they failed. I think the workers were permitted to wear their Clogs
The other story, when my sister got married and moved on to her husbands pig farm, one of the first things she got was a pair of safty boots, a couple of weeks later she was working with the pigs, when one of them stood on her foot, the toe cap was no use, it picked a spot abut 2″ further up the boot, that put her out of action for the rest of the day, hubby was very comforting, his comment was “they always do that”.
Don’t worry I’v got my safty boots, and I keep away from pigs. Ian S C
