You are the drill crew foreman. At the beginning of the day shift, your helper latches the breakout wrench around the first pipe section as you begin to remove rod sections from a drill hole. Your helper is supposed to step back at this point in case the wire rope holding the wrench should break. He doesn't step back on his own and also fails to respond to you shouting at him to step back. In a split second, you must decide what to do.
There is a related training exercise available entitled Wearing Hearing Protection Properly: A 3-D Training Aid for Drillers.
