Wood fires are banned in the Bay Area on Monday, the first "Spare the Air" day issued by the Bay Area Air Quality Management District.

Burning wood or other solid fuels both indoors and outdoors is banned within the air quality district, which includes Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara and parts of Sonoma and Solano counties.

The alert was issued because air quality is expected to be unhealthy on Monday, the air quality district said.
