GRASSY BUTTE, ND – Federal workplace safety investigators determined that an oil company’s failure to take adequate safety precautions contributed to a drilling site explosion near Grassy Butte on Nov. 4, 2021, that permanently disabled one worker and left two others with serious injuries.
A U.S. Department of Labor Occupational Safety and Health Administration investigation found KLX Energy Services – operating as KLX Wireline LLC – carelessly transported explosive materials and failed to take required precautions to protect workers and the public during blasting operations. The workers suffered shrapnel injuries when a perforating gun detonated as workers assembled a blasting cap on it to send down a well near Grassy Butte. The workers were using perforating guns to fracture the well bore.
“These individuals suffered serious injuries simply for doing their job,” said OSHA Area Director Scott Overson in Bismarck. “KLX Wireline LLC’s willful failure to follow federal standards is unacceptable and a violation of their employees’ rights to a safe workplace.”
OSHA cited KLX Wireline for failing to equip vehicles transporting explosives with at least two fire extinguishers located near the driver’s seat, ensure safe and consistent disposal or reuse of empty containers and paper fiber packing materials used to wrap explosive materials, and ensure the vehicles were always attended. OSHA inspectors also noted the vehicles lacked safety placards indicating the presence of explosive materials.
OSHA issued six willful, three serious and two other-than-serious safety violations to KLX Wireline and proposed penalties of $453,982. The agency issued one serious safety citation and proposed penalties of $14,502 to Brigade Energy for exposing workers to hazards during the handling of explosives during perforating operations.
KLX employed the worker who suffered disabling injuries. Brigade Energy of Greenwood Village, Colorado, employed the other two workers.
