Crews were working to assess the damage at a Valero refinery where a fire on Friday sent 19 people to the hospital.
Company spokeswoman Mary Rose Brown said yesterday that the McKee refinery in Sunray remained a "highly sensitive area" and access remained restricted.
She didn't know how extensive the damage was or how long it would take to repair the facility.
Friday's blaze is believed to have started at the refinery's "propane de-asphalting unit," where fuel is processed at high temperatures.
Two Valero employees and a contract worker were transferred to University Medical Center's burn unit in Lubbock on Friday night. One remained in critical but stable condition last night and the other two were in satisfactory condition. The other 16 people who were taken to hospitals had all been treated and released.
