METAL/NONMETAL MINE FATALITY -On October 20, 1999, a 29-year-old electrician with 5 years mining experience was fatally injured at a phosphate operation. The victim was connecting phase conductors in the electrical distribution panel when a co-worker inadvertently engaged the disconnect switch for the circuit resulting in a fatal electrical shock. The electrical disconnect switch had not been locked out nor had a warning sign been attached to it prior to work commencing on the circuit.
