Check Before You Burn Season Continues through February

Sitting next to a fireplace may provide comfort and warmth, but few people may realize that it can be detrimental to health and act as a source of air pollution.

Wood smoke contains many kinds of pollutants including PM2.5, also known as fine particulate matter. This can affect those with respiratory conditions such as asthma or COPD, along with children, who are more sensitive to these pollutants.   

During the winter months, South Coast AQMD issues mandatory no-burn alerts on days when fine particulate levels are expected to be high. Wood-burning can emit more than five tons of harmful fine particulate matter (PM2.5)  per day in the South Coast Air Basin. This is more than three times the amount of PM2.5 emitted from all of the power plants in the Southland. If we can reduce the amount of wood burning, this will help in meeting the federal air pollutant standards for PM2.5.

January and February are the final two months of Check Before You Burn season. Sign up to receive no-burn alerts via email or text at and don’t forget to make the pledge to protect public health by not burning wood on no-burn days. Spread the word on social media using the hashtag #CheckBeforeYouBurn. For more information, visit
