WEST BOUNTIFUL -- A leak of hydrofluoric acid forced the evacuation of the Holly Refinery on Friday.

About 600 workers were in the refinery at the time.

South Davis Metro Fire Chief Jim Rampton says refinery workers contained the leak before fire and hazardous materials crews arrived.

One man was taken to the hospital with minor acid burns.

Rampton says the refinery is shut down to undergo maintenance and upgrades
