Chileno Fire Prompts Sonoma County Health Warning

SONOMA COUNTY, CA — As firefighters began gaining ground on a fire burning along the Marin-Sonoma border, Sonoma County health officials warned that smoke from the blaze could reach unhealthy levels.

Marin County authorities said Sunday evening that fires in the Chileno Valley have been stopped. Firefighters contained one of the smaller fires Sunday at about 4:50 p.m.

At 6:58 p.m., firefighters contained the two remaining vegetation fires.

The Chileno fires burned about 340 acres combined. Authorities said they will be investigating the source of the blaze. No evacuations were ordered.

Health officials warned that the smoke could cause adverse health effects across Sonoma County and the region, while high temperatures could worsen the effects.

County health officials advised residents to check on neighbors, family members, and others who may need help.

Residents should watch for coughing, wheezing, shortness of breath, chest tightness, a scratchy throat, or unusual fatigue. Anyone whose symptoms worsen should contact a health care provider.

Officials also recommended drinking water throughout the day to help the body manage smoke exposure.

Residents should avoid smoking, wood burning, lawn mowing, driving, barbecuing, painting, and other activities that produce dust or worsen air quality. A stove vent should be used while cooking when possible.

Pets should also remain indoors when possible. Farm animals should be checked on them and provided with plenty of clean, fresh water

Air quality can fluctuate across Sonoma County because of several factors. Officials advised residents to monitor conditions where they live and work and take precautions if air quality worsens.

Anyone who must go outside should wear a well-fitting N95 or KN95 mask. People with heart or lung conditions should consult a health care provider before using one.

Residents should use portable HEPA air cleaners when available and set air conditioners and vehicle ventilation systems to recirculate air.

More information for protecting workers outside is available on the Cal/OSHA wildfire smoke emergency standard.
