OSHA investigating explosion at Wallace County oil-drilling site
UPDATE--Tuesday (12/13/16): OSHA is investigating the Monday morning explosion at an oil-drilling site near Sharon Springs that left five injured, two critically.
Fire officials say crews were adding pipe on a rig for the Murfin Drilling Company when the explosion happened.
OSHA says Murfin Drilling has been cited seven times since 2006, including an incident involving a death near Great Bend in 2008.
Five people were hurt, two critically in a gas explosion Monday morning at an oil-drilling site south of Sharon Springs in Wallace County.
Wallace County Fire Chief Jay Sharp says crews were adding pipe on a rig when the gas "migrated up" and got onto the deck floor of a warming hut, which includes running heaters.
Sharps says something electric sparked, causing the explosion. He says the five hurt were hospitalized and the two with critical injuries were airlifted from a hospital in Tribune.
Sharp says responding crews were able to put the fire out quickly once they arrived.
