A fire broke out at the Shell Refinery around 2 p.m. Monday, a Shell spokeswoman said. No damage was reported.
The fire was in the light oil processing unit, according to Shell spokesperson Erin Hallissy.
"The unit was immediately evacuated and all personnel are accounted for," she said. "Our fire crews responded and quickly put it out. They continued to put water on the unit to cool it down."
Shell also notifed the Contra Costa Health Services Department that the facility had a level 2 incident, which does not require a shelter in place warning, but people with respiratory problems were advised to avoid the area.
