The Northern Sierra Air Quality Management District and the Public Health Departments of Nevada, Plumas and Sierra Counties are issuing a Joint Air Quality Health Advisory due to the likelihood of poor air quality conditions through Monday, August 1, 2022 resulting primarily from the Oak Fire near Mariposa County, CA.   

Wildfire smoke may be intermittent and affect different areas within the three counties of Nevada, Sierra and Plumas with elevated levels of particulate matter dependent upon wind direction.

Poor air quality has the potential to cause negative health impacts, particularly for sensitive groups and when exposure is prolonged.   

Exposure to elevated PM2.5 (fine particulate matter in smoke) concentrations can result in eye and throat irritation, headaches, nausea, shortness of breath, congestion, coughing, impaired lung function and chest pain, especially among sensitive individuals such as the elderly, children, people with asthma, people with heart or lung conditions, pregnant women and anyone who is exercising or working hard outdoors. 

If you smell or see smoke around you, the following actions are recommended:

  • Minimize outdoor activities even if you are considered healthy;
  • Stay indoors with doors and windows closed as much as possible; run the air conditioner on the “recirculate” setting if that is an option;
  • People with asthma should follow their personal asthma management plan;
  • People with heart disease, respiratory conditions or chronic health issues should stay indoors;
  • Contact your doctor if you have any symptoms of cough, shortness of breath, chest pain, or severe fatigue;
  • Keep airways moist and stay hydrated by drinking plenty of water;
  • Avoid breathing additional smoke, such as from cigarettes/Vape pens or barbecues.
