You and Lynwood are maintenance mechanics repairing a piece of equipment in the float plant. It is night shift. You are on the fifth level. It is dark and wet. No one else is around. You decide to use an electric impact wrench to break a coupling on an acid mixer. A nearby wall mounted 110V receptacle is dripping water. Because it is dark, Lynwood does not see the water dripping from the receptacle. You try to warn him, but he approaches the receptacle and plugs the wrench in. Then he convulses. You must decide what to do to help Lynwood and not get electrocuted yourself.
