Fran,
Yeah, I realized that they were in short sleeves "after" you pointed that out...oh well, might have to find a few more subjects to take pics of who are wearing sleeves.
I remember two accidents here at the shop involving someone getting burned pretty badly, one guy was cutting with the torch and had worn out gloves with holes in one of the fingers, as he cut he was guiding the torch with that hand and somehow got the torch caught in that hole in his glove and really burned his fore finger. The other guy was heat straightening some beams after welding, he heated several spots on one beam, turned around and was heating a few spots on the next beam over and backed his buttocks into the beam where he had just heated. it was hot enough that it burned through his work pants and his underwear and got a spot on his cheek pretty good. He was more embarrassed than anything.....especially when the nurse had him bend over the table to apply the burn cream to his butt....LOL
