Two people have been injured after a fire at an oil refinery in Wynnewood yesterday morning.

 CVR Energy says the fire, at Wynnewood Refining near Highway 77 and Powell Avenue, started around 8:20 in the gasoline hydrotreater. The hydrotreater is used to remove contaminants during the refining process. Garvin County Emergency Management Director Dave Johnson says all workers have been accounted for. Johnson says the injured were transported for treatment to Mercy from Pauls Valley and Wadley’s from Wynnewood.

 Just before 12:30, the source of the fire was isolated and emergency crews extinguished the fire. CVR Energy says an internal investigation will be conducted. No word on if an investigation will be conducted by OSHA.

 Wynnewood is located an hour south of Oklahoma City.
