Abstract: On December 4, 2004, Employee #1 and a coworker were assigned to clean peanut hulls from a hopper that had previously caught fire. The hopper measured 10.6-feet long by 20.6-feet wide by 29-feet deep and was three quarters full of peanut hulls that were sticking to the sides. Employee #1 and the coworker entered the hopper through a 30-inch long by 30-inch wide opening. They did not use proper confined space entry procedures nor was a harness used. As the coworker was located inside the hopper near the side exit ladder, Employee #1 disappeared into the peanut hull after poking the hull with a pole. The coworker immediately exited the hopper and notified the site supervisor, who contacted emergency services. Employee #1 was removed from the hopper and pronounced dead by medical personnel.
