LOS ANGELES (CNS) — The South Coast Air Quality Management District Monday extended a mandatory prohibition on indoor and outdoor wood burning in much of the Southland through Tuesday night due to a forecast of high air pollution in the area.

The residential wood-burning ban is now in effect through 11:59 p.m. Tuesday for all those in the South Coast Air Basin, including the non-desert portions of Riverside, San Bernardino and Los Angeles counties and all of Orange County.

Monday was the fifth straight day the ban was extended. The original ban had been in effect through 11:59 p.m. Thursday.

The order does not apply to mountain communities above 3,000 feet, the Coachella Valley or the high desert. Homes that rely on wood as a sole source of heat, low-income households and those without natural gas service also are exempt from the requirement.

The no-burn rule prohibits burning wood as well as manufactured fire logs, such as those made from wax or paper.

Gas and other non-wood burning fireplaces are not restricted, the SCAQMD said.

Fine particles in wood smoke, also known as particulate matter or PM2.5, can get deep into the lungs and cause respiratory problems such as asthma.
