The Bay Area Air Quality Management District has banned the burning of wood, manufactured logs or any other solid fuel, indoors or outdoors, for 24 hours.
The ban — making it illegal to light a New Year's Day fire — has been put in place to avoid trapping pollutants in atmosphere, according to the district.
Cold, still weather due to continue through mid-week causes air to cool close to the ground, creating an inversion layer of warmer air above. In windless conditions, wood smoke and other pollution can get trapped under this lid of warm air can and build up rapidly to unhealthy levels.
"Sitting by the fire during the holidays may conjure up fond memories, but it’s important that everyone forgoes burning during this alert so we can all enjoy a happy, healthy holiday," Air District executive officer said Jack Broadbent said.
The district says that exposure to wood smoke — as with cigarette smoke — has been linked to serious respiratory illnesses and even increased risk of heart attacks. Breathing fine particles or soot accounts for more than 90 percent of premature deaths related to air pollution, according to BAAQMD.
It is illegal for Bay Area residents and businesses to use their fireplaces during a Spare the Air Alert. Woodstoves and inserts, pellet stoves, outdoor fire pits, or any other wood-burning devices are included in the ban. An exemption is available for residents and businesses that burn wood as their sole source of heat and have no other permanently installed heating source, according to the district.

Wood smoke is the largest source of wintertime air pollution in the Bay Area, according to BAAQMD, and contains harmful pollutants such as particulate matter and carbon monoxide, as well as toxins which are linked to increased cancer rates in adults. In the winter, wood smoke from the 1.4 million fireplaces and wood stoves in the Bay Area contributes about one-third of the harmful particulate pollution in the air.
