CHEYENNE, Wyo. (AP) — Wyoming safety regulators are seeking more than $60,000 in penalties against Sinclair Oil for a refinery fire that injured two workers.

The fire happened May 25 at the Sinclair Refinery in the town of Sinclair in south-central Wyoming. Three such fires at the refinery since early May have injured a total of seven workers.

The Wyoming Department of Workforce Services Occupational Safety and Health Administration Office announced a dozen citations against Sinclair on Friday. Eleven of the 12 citations were considered serious.

The violations include failing to inspect equipment and correct deficiencies, and failing to develop and implement safe work practices.

A spokesman for Salt Lake City, Utah-based Sinclair said Friday the company takes responsibility for possible safety deficiencies at the refinery and is working urgently to correct them.
