CSB to investigate Utah refinery blast, fire which injured four people

A four-member team will travel to Woods Cross, Utah, to investigate a Jan. 12 refinery explosion and fire which injured four people, the US Chemical Safety and Hazard Investigation Board said on Jan. 13.

The fire at the Silver Eagle refinery injured two employees and two contract workers who were standing about 10 feet from a tank filled with flammable hydrocarbons when it exploded, CSB said. All were hospitalized for treatment of second and third-degree burns.

Fire crews evacuated other employees and residents within a half-mile radius soon after the blast which occurred around 5:30 p.m. MST. Evacuees waited at a high school before they were permitted to leave four hours later. The fire was extinguished by 3:45 a.m. on Jan. 13.

An official for Silver Eagle Refining Inc., which bought the 10,250 bbl per day plant from ConocoPhillips Co. in 2003, said that the company would begin working immediately with federal and local investigators to determine the explosion and fire's cause.

CSB said that its crew, which was scheduled to arrive the afternoon of Jan. 14, would be lead by investigator supervisor Donald Holmstrom.
