Fatality Assessment and Control Evaluation (FACE) Report for New York: Worker Dies after Falling through a Steel Grid Plate into an Underground Frozen Coal Cracker

摘要

On February 11, 2003, a 42 year-old male material handling operator, who was employed at a coal-fired electrical generating plant, sustained fatal injuries as a result of falling 15 feet through a steel grid into an underground coal cracker. On the morning of the incident, coal from an emergency stockpile was transported through a ground opening that was covered by a steel grid called a 'grizzly'(14' X 14') with 12 inches by 12 inches grid openings. Under the grizzly there was a 15 feet deep hopper, a coal cracker, and a second hopper that was 12 feet deep connected to a conveyor belt. On January 22nd, nineteen days before the fatal incident, an operator had recorded damage to the grizzly in the team's daily log: the steel bars (1 inches X 10 inches) that formed the grids were broken and bent resulting in a 2' by 2.5' hole in one corner of the grizzly. A decision was made within the team not to repair the grizzly until spring. On the morning of the incident, the victim was seen by two of his co-workers (an operator and an engineer) walking on the grizzly with a shovel in his hand. It appeared that the victim was using the shovel to break the frozen coal and clear the clogged grids. Then, at approximately 9:18 AM, the engineer noticed that the shovel was left on the grizzly but the victim was gone. He immediately told the operator to shut down the coal transporting system. The victim was found on the conveyor belt 50 feet away from the grizzly. The victim apparently fell through the hole on the damaged section of the grizzly into the hoppers and the frozen coal cracker and was carried out by the conveyor belt. The operator immediately called an incident commander in the plant's master control room. The incident commander summoned an ambulance that arrived at the site in ten minutes. The victim was transported to a local hospital where he was pronounced dead.
