Outdoor Air Quality
Outdoor air quality and visibility may be affected due to forest fires. Wildfire smoke can be harmful to everyone’s health even at low concentrations. Individuals with respiratory conditions or other at risk populations are at a higher risk of experiencing health effects caused by smoke. If you must spend time outdoors, a well-fitted respirator type mask (such as a NIOSH certified N95 or equivalent respirator) that does not allow air to pass through small openings between the mask and face, can help reduce your exposure to the fine particles in smoke. Check the Air Quality Health Index (AQHI) and monitor your symptoms.

Understanding the Air Quality Health Index
The Air Quality Health Index (AQHI) is a tool used to understand how air pollution can affect your health. It uses a scale from 1 to 10+, with higher numbers indicating a greater risk. Here’s what the numbers mean:
- Low Risk (1–3): Ideal conditions for outdoor activities for everyone.
- Moderate Risk (4–6): Most people can continue outdoor activities, but those with heart or breathing problems should monitor for symptoms.
- High Risk (7–10): Consider reducing or rescheduling strenuous outdoor activities, especially if you experience symptoms like coughing or throat irritation.
- Very High Risk (10+): Everyone should avoid strenuous outdoor activity. Those at higher risk should stay indoors and limit exposure.
