A mandatory No-Burn Day alert has been issued by the South Coast Air Quality Management District, prohibiting all residential wood burning in the South Coast Air Basin due to high levels of air pollution.
The alert, which will be in effect from midnight to 11:59 p.m. Friday, applies to residents in Orange County and the non-desert areas of Los Angeles, Riverside and San Bernardino counties.
Exemptions apply to mountain communities above 3,000 feet, the Coachella Valley, and the High Desert, as well as homes that rely on wood as their sole heat source or are in low-income households without natural gas service.
The No-Burn rule bans the burning of wood, including manufactured fire logs made from wax or paper, in fireplaces and any indoor or outdoor wood-burning devices. The purpose of the ban is to protect public health when high levels of fine particulate air pollution are forecast.
“Smoke from wood burning can cause health problems. Particles in wood smoke — also known as fine particulate matter or PM2.5 — can get deep into the lungs and cause respiratory problems, including asthma attacks,” South Coast AQMD said in its statement.
This is the first No-Burn alert for the 2024-2025 season.
A smoke advisory was also issued for most of the Los Angeles area due to the Mountain Fire burning in Ventura County.
Smoke was expected to most heavily impact the areas including the San Gabriel Mountains, San Fernando Valley, Santa Clarita Valley, Northwest coastal Los Angeles County and part of West San Gabriel Valley.
Officials urged Angelenos to stay indoors with windows and doors closed, use air conditioning or air purifiers to limit exposure, and avoid vigorous physical activity outdoors. They say to also minimize indoor air pollution by not burning wood or using candles, and wear a properly fitted N95 or P100 respirator if you must go outside.
Heavy winds also kicked up ash and dust into the air, leading to a Windblown Dust and Ash advisory being issued Wednesday.
