Four workers were hurt, with three in critical condition in a burn center, following a fire at the Sinclair Oil Corp. refinery in Wyoming, according to Wyoming Trib.com.
The fire started shortly after 10 a.m. Tuesday in the refinery’s gas recovery unit, which is a few miles from Rawlins, Wyoming.
Refinery employees Tim Bjork, Eric Hansen and Quinn McCartney were transported by air to Northern Colorado Medical Center in Greeley, Colo., according to Trib.com. The fourth injured worker, David Jaramillo, was taken to and received treatment at Carbon County Memorial Hospital. He was released Tuesday night.
All four men were wearing flame-retardant clothing when the fire broke out, Trib.com reported.
The Occupational Safety and Health Administration was investigating the cause of the fire at the refinery, which has had several safety issues before Tuesday’s incident.
The Wyoming facility had fires two days in a row in September in its oil processing unit, Trib.com reported.
Sinclair Wyoming Refinery Corp. paid a $5.4 million settlement to state regulators in June following a 2010 oil leak into waste water ponds that killed numerous birds, according to Trib.com.
In total, the refinery has forked over $7 million to Wyoming environmental regulators in the past few years for the disbursement of pollution “into the sewers and dangerous gas into the air,” according to Trib.com.
Sinclair is headquartered in Salt Lake City.
