After a valve turned wrong and a pipe became disconnected, a 49-year-old Duluth, MN, died in a hydraulic fracturing accident in North Dakota.
Mike Krajewski died about 3:30 p.m. Saturday at a Halliburton location about 24 miles north of Watford City, ND, said the McKenzie County Sheriff’s Office.
The North Dakota Medical Examiner’s Office ruled Krajewski’s death an accident caused by oilfield equipment dislodged by high pressure, striking him in the chest.
While the Occupational Health and Safety Administration is in the process of investigating the incident, a preliminary report indicates a valve turned wrong and a pipe disconnected and hit him in the head, said Sgt. Matt Johansen. Krajewski’s job involved pumping fluids at high pressures.
A Halliburton spokeswoman says the company will continue to work with local authorities as they investigate the incident. “This is a very difficult time for all of us at Halliburton, and our thoughts and prayers are with our employee’s loved ones,” the company said in a statement.
Another worker, Brad Hong, 55, of Halliday, N.D., also suffered an injury Saturday and went to the McKenzie County Hospital for injuries believed to be minor, Johansen said.
