The employee climbed over into a Gleason Clay Shredder to remove a piece of metal without locking the machine out. EE only killed the power. Another employee came by and started the machine. EE lost part of EE's left leg.
Was disconnecting wiring from an auger that was no longer in use. Checked for voltage with pocket type voltage detector and no voltage was detected. I reached into the box to remove wires from disconnect and two of the wires touched and caused arc flash from where the wires were still energized. The arc flash caused 1st & 2nd degree burns to left hand & inner forearm.
