You are the weigh master at the scales at the truck dumping bins at a preparation plant. Jake, a truck driver, raises the bed of his truck to dump a load in a bin. The load won't dump and the truck bed won't come down. The bin appears to be full. Jake climbs into the bin on top of the coal. Suddenly the bridge of coal collapses. The 20 tons of coal in the bed of the truck slides out and buries Jake in the bin. You must decide what to do to help him without risking your life or the lives of others.
