Officials from the Occupational Safety and Health Administration are investigating a fatal crane accident in North Dakota, the second oil field death in the state in less than a week.
According to the Grand Forks Herald, an Advanced Energy LLC employee was killed Monday morning when an overhead crane fell on top of him at a site in Stanley.
An OSHA official told the paper that a drilling crew was removing pipe to replace an underground survey tool when the crane fell.
That accident occurred just two days after another fatal accident in North Dakota.
One man was killed and three others were injured on Saturday after a flash fire at an XTO Energy operated site near Watford City.
Johnny Stassinos, 52, died as a result of the accident.
Daniel Montes, 28, and Richard Maheu, 27, suffered third-degree burns across 70 percent of their bodies and are currently listed in critical condition.
Justin Pyle, 40, was treated for minor burns and released from the hospital, according to the AP.
Investigators told the AP that a preliminary investigation found that a breached gas pipe ignited as the men were working on a workover rig.
According to the Bismark Tribune, OSHA has launched a probe into the accident and an OSHA official was expected to visit the site on Monday.
An XTO Energy spokesperson told the Bismark Tribune that the men were employed by Most Wanted Well Service and SEI Well Service.
No spills were reported in connection with the accident.
