This was a reference to the machine shop in general and lathes in particular. Cloth will sooner or later get caught in rotating machinery. This is the same reason why machinists don't wear long sleeved shirts. I haven't heard of any glove type being exempt from this rule. Hair and beards are definitely discouraged as well. When I was in the air force wedding bands were discouraged during ground battle exercises given the ease of getting caught on something and losing a finger.
I think this is a good example of why the safety guidelines are strict and mostly require rote learning. Gloves protect against heat, but everything you have been plasma cutting or welding needs to be handled with tongs because even if the metal doesn't glow it's probably still pretty hot. Most of these rules make sense in retrospect, but they are universally hard to deduce from first principles.

This is very true. I haven't welded since high school, but a single arc weld can get a piece of metal hot enough to burn almost instantly through heavy leather gloves.
