Working at that tool and die shop I consult for, there were some pretty strict rules about clothing wear.
But the closest call I saw was hair.......
They had hired this girl in the office with long hair. She was married to a biker, and wore it in a long braid that reached below her waist.
There are lots of machines out on the floor, and there are painted safe lanes you normally walk when moving around.
The shipping desk is in the back of the shop, since most things that get shipped go right from the shop to the truck.
I had run a network line out there, and you could make up a shipping label, invoice, whatever you needed and print it out right there.
I was waist deep in a big machine trying to figure out why it would not hold tolerance, when she came walking by to get some parts ready to ship.
There was a big LaBlond lathe running and when she walked by and turned the corner, her braid swung out over the piece of stock spinning in the lathe.
Somehow, it did not quite touch the stock. I was too far away, and yelling would have done no good.
A little while later, I had found the problem and needed her to order a part. As I was headed up front, I checked that lathe and saw what it was doing.
Started doing the math in my head as I walked up.
2 inch bar stock, turning at 1000 rpm.
Pi equals 3 when I'm doing the math in my head.
So, 6 inch circumference, @1000 rpm equals 500 surface feet per minute.
Assuming her hair was 5 feet long, it was not much over 4 probably, but still doing head math, that meant it would have wound her into the lathe in 1/100 of a minute. In other words, 6/10 of a second.
After I got the part ordered, I mentioned that she might want to do something about her hair.
She got real defensive real quick. I guess she had been criticized about it at another job.
Started talking about how management could not dictate her hair style......
I let her run down, and pointed out a couple of things.
First, I was not management. I did not even draw a salary. I was a consultant.
Second, I had seen that lathe shave off a 1/4 thick strip of cold rolled steel without a strain.
It would not even notice her.
Told her the figures on how fast it would be, and then told her one of two things would happen.
It would either rip her entire scalp off leaving her with naked bone on top of her head.
Which I had seen happen on a shrimp boat,
Or wind her head and the rest of her body around that piece of steel.
Which would be the worse is a matter of opinion. Some women would rather die than be disfigured like that.
Told her it did not matter to me either way, I did electronics work, not cleanup.......
From then on, as long as she worked there, she would go to her desk in the morning, coil up that hair and pin it up.
Then take the pins out as she was leaving to go home that afternoon.
I told her it was only necessary when she had to go back to the shop, but she said she did not want to take a chance on forgetting.
