COAL MINE FATALITY - On Sunday, April 30, 2000, a 26-year-old underground electrician, with 5-1/2 years mining experience, was fatally injured when he came in contact with an energized high voltage circuit on a High Tech Electric Section Power Distribution Center. The victim had been assigned to replace two circuit breakers on the power center, which would not have required the victim to enter the high voltage side of the power center. At the time of the investigation, visibility was impaired on one of the two sight windows that are provided to determine the position of the knife blades which are used as a visible disconnect. Since one of the blade switches could not be seen through the windows, it is believed that the victim opened the lid to the 7200-volt incoming power to ensure that all three of the knife blade switches were in the open position. The power center was equipped with lid switches to de-energize the power when the lids were opened; however, the lid switch on the high voltage compartment had been defeated. There were no eyewitnesses to the accident.
This is the tenth fatality reported in calendar year 2000 in the coal mining industry. As of this date in 1999, there were eleven fatalities. This is the second electrical fatality reported in the coal mining industry in 2000. There were no electrical fatalities reported in the same period in 1999.
