You are at a surface mine in a pickup truck. You see Harry placing crib blocks between the frame and the bed of a large haul truck. The operator is in the haul truck cab. Suddenly the bed drops down, pinning Harry. If it were not for the blocks, Harry would have been cut in two. The operator quickly raises the bed. Harry falls to the ground near the rear wheels. The radios in both the haul truck and pickup are broken. It is 20 minutes by pickup truck to the nearest help. You and the haul truck operator must figure out what to do for Harry.

This exercise is similar to the "Continuous Miner Accident (invisible ink)" exercise.
