METAL/NONMETAL MINE FATALITY - On July 29, 2007, a 29 year-old contractor miner with 3 years experience was fatally injured at an underground zinc mine. The victim and two other contractor miners were working on top of a service hoist located in the main mine service shaft. He was assisting another miner who was using a chipping hammer to remove concrete from around a steel shaft set. The miners had one foot on top of the service hoist and one foot on a cross section H-beam when one side of the beam collapsed. Both miners fell into the shaft. They were both wearing safety harnesses and lanyards but the victim's lanyard was not secured. The other miner was caught by his lanyard but the victim fell 1,000 feet to the shaft bottom.
Ensure workers are trained and understand that safety lanyards are not permitted to be unfastened while working at elevated locations. Provide self retracting lanyard mechanisms when workers are required to reposition themselves to perform tasks. Ensure safety lanyards are securely fastened at all times when workers are positioned at elevated locations.
