Two mechanics came out to inspect the Kelly bars. The injured mechanic was facing the excavator operator and signaled the operator to raise the boom, but the Kelly bar raised/collapsed instead. The injured mechanic s right hand slipped into the inner and outer Kelly bars of the drill and the first, middle, and ring fingers were injured.
