You and Carl are maintenance workers at a coal preparation plant. A belt is misaligned because fine wet coal is sticking to the tail pulley roller. You decide to shut the belt down so the roller can be cleaned. Carl says he knows a faster way to do the job. He begins a dangerous work practice. You try to stop him, but it is too late. He gets caught between the moving tail pulley and its guard. He is hurt. You must act fast to save Carl but avoid injury to yourself.
