South Coast AQMD’s annual Check Before You Burn program is set to return, reminding residents to check whether a No-Burn Day has been declared before using wood-burning fireplaces, stoves, or outdoor fire pits.

A No-Burn Day is a 24-hour ban on residential wood burning, including fireplaces, stoves, and outdoor fire pits, in the South Coast Air Basin. These temporary restrictions are called when pollution levels are expected to be high due to air emissions and stagnant weather conditions. High fine particle pollution episodes are most common on calm and cool winter days, when added pollution from wood burning can quickly lead to unhealthy air quality.

Exemptions apply for mountain communities above 3,000 feet in elevation, the Coachella Valley and High Desert, homes that rely on wood as a sole source of heat, and those without natural gas service. Gas fireplaces are also exempt.

Wood smoke contains PM2.5, which can cause throat and eye irritation, aggravate asthma, and trigger respiratory or cardiovascular health problems. Long-term exposure can increase the risk of strokes, heart attacks, and certain cancers. Children, older adults, people with lung or heart disease, and those who spend significant time outdoors are especially vulnerable. Burning wood negatively impacts air quality both indoors and in nearby neighborhoods.

By participating in Check Before You Burn, residents can help improve air quality in their communities and protect public health.
