A worker in New Richmond, WI, was killed in a trenching accident, but not because of a cave-in.
A-1 Excavating employee Eugene Hakes was using a large, gas-powered saw to cut through a water main in a trench.
The saw kicked back and struck him in the neck, police said.
He was taken to a hospital where he was pronounced dead, according to WEAU-TV.
An OSHA spokesman said using the saw in the trench would not be a violation as long as it was operating properly and all the guards were in place. OSHA is investigating.
A-1 recently was fined $700,000 for 11 OSHA citations for life-threatening violations involving a trench project last September.
The company failed to protect workers from possible cave-ins in an 8-foot-deep trench.
A-1 contested those violations and refused to come to a settlement agreement, according to OSHA.
