Ummm ... I guess it depends on exactly what you do. I worked for a
defense contractor for quite awhile, "When you were done with it ...
shred it." One young fellow still had his dog tags on the chain around
his neck. Fortunately they gagged the shredder before the chain
strangled him.

My wife and I sas w photo of someone who had slipped while
climbing and wearing a ring which caught. The skin on the finger
was peeled back like a banana peel. We agreed that no wearing
our rings in circumstances was more than a good idea. We like
each other intact.

One other consideration,if using metal tools around high current

After pain, visual learning is often the best teacher. The rest of us
sense wallet depletion.
Don't forget that some of the battery packs we commonly use now (LiFePo4
is my example) are capable of tremendous current (mine are 'fused' by a
BMS at 100 amps).

Amen! I shorted my wedding ring and a wrench across a car
battery once. It burned out a small part of the ring, and left a
blister that lasted a week. I was lucky. I also got the ring off
before the swelling made it impossible. I was doubly lucky.

I was at a Red Cross headquarters working ECOM when the room filled with
bystanders. All of the power supplies were facing the operators while
their exposed backs were next to the crowd. I noticed a lot of hand
jewelry. I got the most important looking person's attention and
mentioned how a
