“It is difficult to tell where smoke, ash or soot from a fire will go, or how winds will affect the level of these particles in the air, so we ask everyone to remember that smoke and ash to can be harmful to health, even for people who are healthy,” LA County’s Health Officer, Dr. Muntu Davis, said in a statement. “If you can see smoke, soot, or ash, or you can smell smoke, pay attention to your immediate environment and take precautions to safeguard your health.”

Children and people with respiratory conditions were urged to stay indoors as much as possible even in areas where smoke, soot, or ash are not visible, or there is no smell of smoke.
