Abstract: At approximately 4:40 p.m. on January 15, 1988, three employees were working at the bin top level of a grain elevator near the west end of a structure and two employees were in the office just south of the west headhouse entrance when the grain elevator exploded. Of the three employees at the bin's top level, two were blown into an empty bin, the bottom of which was 100 ft below the bin top level. These two employees died of massive injuries. The third employee at the bin top level suffered 2nd- and 3rd-degree burns to his face and hands, as well as a broken pelvis. Of the two employees in the office, one died of massive injuries due to falling steel and concrete and the other suffered 2nd- and 3rd-degree burns to his face and hands.
