As the deadly wildfires that have been wreaking destruction in Los Angeles County enter their second week, the city said it was concerned about the health impacts to vulnerable groups from the smoke.
The N95 masks would be available in public facilities, including libraries, recreation centres and retirement homes.
Sensitive individuals are advised not to leave their homes, keep windows and doors closed, avoid strenuous physical activity and, if possible, use air conditioning or air filters.
Los Angeles declared a health emergency on Friday due to enormous amounts of smoke and fine dust in the air. (dpa/NAN)
