I have a hard time with blanket statements about shop safety. Yes, if you remove gloves from the shop, there will be less glove related injury... there will also be an increase in abrasion and burn related injuries. LEARN to recognize potential dangers and use the appropriate safety gear. Much of what we label as "potentially" dangerous on this site is industry standard for safety, elsewhere. You just have to be smart and understand the equipment you are using.
If your grinder has a rest, there is a pinch point... gloves are a no-no. But if you grind on a wheel or open flat platen, there is little danger and gloves can prevent abrasions. In many of the manufacturing/fabricating shops I've been to, gloves were worn in most grinding and buffing situations. I was in tool and die for 15yrs. Still trying to figure out how gloves are a danger on a buffer... lol.
They need to fit properly, of course. I find the rubber sprayed gloves catch on the belt and jam my fingers. Leather is more expensive but more forgiving, IMO.
