I saw my auto shop teacher in high school be severely burned when his metal banded watch turned red hot. We were working on a 60s model pickup truck, he was holding the ignition switch in his hand, and had his sweaty arm propped on the metal dash, when he turned the key the watch turned bright red in an instant. No permant injury except for a scar arond his wrist. After seeing that I have not worn any metal around electrical work since.
Life is tough, Life is tougher when you are stupid
