FROM THE EPA:
The Butte County Air Quality Management District and the Butte County Public Health Department have issued an Air Quality Advisory to notify the public of poor air quality conditions in Butte County due to smoke from the Cherokee Fire, La Porte Fire, Cascade Fire, and Honey Fire. Take actions to reduce your exposure to wildfire smoke if you’re in an area being impacted.
The major air pollutant of concern during wildfire impacts is fine particulate matter, also known as PM2.5. While all persons may experience varying degrees of symptoms, the more sensitive individuals, such as the young, the elderly, pregnant women, smokers, and those with respiratory conditions are of greatest risk at experiencing more aggravated symptoms. These symptoms may include, but are not limited to coughing, watery and itchy eyes, and difficulty in breathing.
Persons experiencing questionable or severe symptoms during smoky conditions should seek professional medical advice and treatment. The following actions are recommended as needed when wildfire smoke impacts your location:
• Limit your outdoor activities, especially children and people with chronic heart and lung diseases.
• Avoid the use of non-HEPA paper face mask filters and bandannas which are not capable of filtering extra fine particulates (more information);
• Check or replace air conditioner filters. Run air-conditioners on the “re-circulate” setting, if available. A small percentage of newer homes have ventilation systems that actively bring in outdoor air. These should be turned off or set to a “re-circulate” mode. Do not run swamp coolers or whole house fans;
• If you need to drive through smoke, make sure your windows are closed and run your air conditioner on the re-circulate setting.
• If you do not have air conditioning and it is too hot to remain indoors during unhealthy conditions, consider temporarily relocating to an alternative location;
• Reduce sources of indoor air pollution.
