Vent: The new apprentice just used my Klein lineman's pliers to cut a live 12-gauge wire.
I left my tool bag open for two minutes while I grabbed a breaker from the truck. Came back and saw the cut end still smoking. He said he 'thought it was fine' because the wire was in a junction box. What's the dumbest thing you've seen a green helper do on a job site?
Was he trying to make a quick fuse? First thing tomorrow, sit him down with a scrap piece and a meter. Show him how to test, then cut. Makes me miss the steak knife guy @davis.leo mentioned, at least that was a dead wire.
