Explain what an underground worker must do when the emergency alarm sounds. The audience is a new worker who has just finished surface induction and is about to go below for the first time. Open on the concrete moment: he is at the face, the alarm sounds, and every person around him stops and looks in the same direction. Then show what he needs to already know before that moment, where the nearest escape route runs and which direction takes him to fresh air. Turn on the sequence that follows, putting on the self rescuer, moving to the refuge or the escape way, and staying with the group. Land on why he must learn that route on his first day and not on the day he needs it.
