LOS ANGELES (KNX) — A no-burn order is in effect for much of Southern California on Thursday, banning the burning of wood for all residents of the South Coast air basin, according to the South Coast Air Quality Management District.

The 24-hour ban goes into effect Thursday morning at midnight and will be in effect through 11:59 p.m. Residents of Orange County and non-desert portions of Los Angeles, Riverside and San Bernardino Counties are included in the ban and will not be allowed to burn wood or manufactured fire logs in any indoor or outdoor fireplaces.

Residential no-burn days are called for "when PM2.5 is expected to reach unhealthy levels due to air emissions and stagnant weather conditions," South Coast AQMD said in a statement.

"Do your part to help keep our air clean by not burning wood," the department said.

"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), increases in emergency room visits and hospitalizations."

No-burn days do not apply to mountain communities above 3,000 feet in elevation, the Coachella Valley, or the High Desert, South Coast AQMD said.

The No-burn day comes during "Check Before You Burn" season, where South Coast AQMD asks Southern Californians to watch what and where they're burning through the end of February.
