This is why in electrical trade you’re taught to use your right hand, with your right foot below your shoulder, and left leg out (when doing anything sketchy).

If you do get shocked then the current will travel down the right-side of your body, and out through your right leg.

That’s not to say throw caution to the wind, but some people need to do risky things (that’s why sparkies get paid a lot).

For example, a guy I used to work with had to repair a switchboard at the hospital, which supplied power to the theatre rooms. Time sensitive matter as I’m sure you can imagine.

This guy was a pro, and was wise to take the safety precaution. When it came time to power back on the switchboard, not only rid he right-hand/right-foot, he shielded his body and face with the switchboards door panel.

Something inside blew up, and he got his hand burned quite badly. Fortunate for him to be at a hospital. In this cade he didn’t need the right-hand/right-foot technique, but if things happened differently, it could have saved his life.
