The fourth consecutive "Winter Spare the Air" alert has been issued for today.
The Bay Area Air Quality Management District's announcement means that wood, logs, or other solid fuels cannot be burned in fireplaces, fire pits or any other wood burning device indoors or outdoors for 24 hours.
The only exception is for households that depend on wood burning as a heat source.
Dry, mild weather this week has contributed to the buildup of pollutants that make the air unhealthy to breathe, according to the air district.
Those with respiratory conditions, children and elderly residents are advised to limit outdoor activity during Spare the Air days.
Residents who violate the ban will be levied a $100 fine or can take a wood-smoke awareness classes. Repeat violators will receive a fine of $500 or more.
More information about Spare the Air alerts is available at the air district's website at www.sparetheair.org.
This is the 19th alert for the season, which runs until Feb. 28.
