My Brother is a mason. He was told not to wear his Ring because it could cause problems. He showed up at work and they boss dumped a brick next to his ring finger. Had it hit, it would have crushed the ring and he would lose his finger before they could open the ring. He never wears a ring to work anymore.
I am an Electrical Technician. You want a good zap? Wear a GOLD ring in a 440 VAC electrical cabinet and see how the sparks fly. Take the ring off and leave it off exept for special occations.
(Air Force Jet Tech, jumped from a scafold, about 5 feet. Wedding band stuck to the scafold. he lost the ring finger and the ligament in it all the way to the elbow.)
