Residents of Richmondy, North Richmond and San Pablo are being told to shelter-in-place after a fire broke out at a Chevron refinery in Richmond. Authorities are asking people to go inside, close all windows and doors, and turn off fans, heaters and air conditioners. Residents should close fireplace dampers and vents, cover cracks around doors and windows with tape or damped towels. Large flames with thick black smoke are coming out of at least two refinery stacks at the facility. The black smoke is visible from as far away as the bay bridge. John Hamilton has this report:
