Abstract: An employee at a surface mine was employed in two capacities: during the day, as the mine's plant operator and, at night and on weekends, as a live-on-site watchman in an employer-provided mobile home. (The residence was on mine property and received its power from the mine's generator.) The employee lived in the home with his pregnant wife and 4-year-old son. Shortly before 11:00 PM, the employee's wife awoke and discovered a fire originating in a receptacle outlet supplying power to an electric heater used to heat the home. The employee and his wife initially escaped the burning home, but the employee reentered with a water hose to rescue his son. Unfortunately, the employee and his son died in the fire.
