Two workers at the Sinclair refinery near Rawlins were injured in a late-night fire on Friday, a Sinclair spokesman said.
One worker was treated and immediately released while the other was treated but not released until Monday. Sinclair didn’t reveal the names of the workers.
Carbon County Memorial Hospital in Rawlins, which likely treated both workers, didn’t immediately respond to an information request.
The “brief fire” occurred at 11 p.m. Friday during start-up of a pump in the refinery’s alkylation unit, Sinclair spokesman Clint Ensign said in an email Tuesday.
Damage was limited to the pump and the refinery is currently operating, he said.
A spokeswoman for the Wyoming Occupational Safety and Health Administration didn’t respond to a request for comment Tuesday.
The fire was the refinery’s second in less than a month, and the latest in a long string of safety and environmental problems at the refinery.
A May 8 flash fire in the refinery’s gas recovery unit burned four workers, three severely.
While worker David Jaramillo was treated and released the same day, fellow workers Tim Bjork, Eric Hansen and Quinn McCartney were flown to a Greeley, Colo., medical center. Bjork remains hospitalized in satisfactory condition at a Salt Lake City burn center. Wyoming OSHA’s investigation showed all four men were wearing flame-resistant clothing.
That fire and the injuries are still under investigation by Wyoming OSHA.
At least three citations will be issued to the refinery because of the May 8 incident, John Ysebaert, administrator of standards and compliance for the Wyoming Department of Workforce Services, said in an interview last week.
The Sinclair refinery processes about 80,000 barrels of crude oil a day, including oil from the Canadian tar sands, into gasoline and diesel. The refinery was founded in 1923.
