Friday will be the 26th day this season that an alert has been issued by the Bay Area Air Quality Management District, which is banning wood burning in the region because of poor air quality.
A dry, stagnant weather pattern with little wind continues to linger in the Bay Area and does not appear to be leaving any time soon, air district officials said.
"Unfortunately, weather conditions that allow smoke to build up and cause public health impacts have not changed," Jack Broadbent, executive officer of the air district, said in a statement today.
During a Spare the Air day, residents and businesses cannot use fireplaces, woodstoves, outdoor fire pits or any other wood-burning devices indoors or outdoors.
Homes that only have stoves or fireplaces as a source of heat are exempt from the ban.
Violators are subject to a $100 fine or the option to take a wood smoke awareness class. Violators face a $500 fine or higher for subsequent offenses.
Wood smoke has fine particles and other pollutants that make the air harmful to breathe and cause air pollution, according to the district.
Children, the elderly and those with respiratory conditions are most susceptible to the effects of poor air quality, district officials said.
This winter has seen the worst air quality since 2006, primarily due to the dry weather, air district spokesman Aaron Richardson said.
There were 30 "Winter Spare the Air" days for the entire winter season in 2006-2007.
"We are threatening our record for (alerts). And we're only halfway through the season," Richardson said.
The winter season started Nov. 1 and runs until Feb. 28.
