OSAA Air Quality Guidelines – Revised May 2018
These guidelines, created in consultation with the Oregon Health Authority (OHA), provide a default policy to those responsible or sharing duties for making decisions concerning the cancelation, suspension, and/or restarting of practices and contests based on poor air quality.
A. Designate Personnel: Given the random behavior of wind and air currents, air quality may change quickly. Schools shall designate someone who will monitor the air quality prior to and during outdoor activities. While typically due to wildfires, schools need to also consider non-wildfire situations if the air quality is unhealthy.
B. Areas With Air Reporting Stations: The Air Quality Index (AQI) should be monitored throughout the day, and during an event, to have the best data possible to make informed decisions about conducting practices and competitions. School personnel shall review the AQI information for all regions throughout the state on either the Oregon Department of Environmental Quality (DEQ) website at https://oraqi.deq.state.or.us/home/map, the Oregon DEQ app “OregonAir”, or on the Environmental Protection Agency (EPA) Air Now website at https://airnow.gov/index.cfm?action=airnow.local_state&stateid=38 to determine if action is necessary (see chart below). Schools shall regularly review the AQI throughout events to assess deteriorating conditions.
C. Areas Without Air Reporting Stations: Given the random behavior of factors related to the calculation of the AQI levels in different areas of the state (wind speed and direction) member schools not near a reporting station should consult with local state and/or federal authorities to help determine the AQI level in your specific area. If air monitoring equipment is not available, member schools should utilize the 5-3-1 Visibility Index to determine air quality.
5-3-1 Visibility Index:
Making visual observations using the 5-3-1 Visibility Index is a simple way to estimate air quality and know what precautions to take. While this method can be useful, you should always use caution and avoid going outside if visibility is limited, especially if you are sensitive to smoke.
Determine the limit of your visual range by looking for distant targets or familiar landmarks such as mountains, mesas, hills, or buildings at known distances. The visual range is that point at which these targets are no longer visible. As a rule of thumb: If you can clearly see the outlines of individual trees on the horizon it is generally less than five miles away. It is highly recommended that schools use pre-determined landmarks that were established on a clear day to determine their visual range.
Ideally, the viewing of any distant targets should be made with the sun behind you. Looking into the sun or at an angle increases the ability of sunlight to reflect off of the smoke, thus making the visibility estimate less reliable.
Be aware that conditions may change rapidly and always use the more conservative of multiple metrics (AQI, 5-3-1 Visibility Index, etc.).
D. Act: This chart will help determine the action needed based on the air quality in your area.

Required Actions for Outdoor Activities
51 – 100 5-15 Miles
Athletes with asthma should have rescue inhalers readily available and pretreat before exercise or as directed by their healthcare provider. All athletes with respiratory illness, asthma, lung or heart disease should monitor symptoms and reduce/cease activity if symptoms arise. Increase rest periods as needed.
101 – 150 3-5 Miles
Because they involve strenuous activity for prolonged periods of time, all outdoor activities (practice and competition) shall be canceled or moved to an area with a lower AQI. Move practices indoors, if available. Be aware that, depending on a venue’s ventilation system, indoor air quality levels can approach outdoor levels.
151 – 200 1-3 Miles
Because they involve strenuous activity for prolonged periods of time, all outdoor activities (practice and competition) shall be canceled or moved to an area with a lower AQI. Move practices indoors, if available. Be aware that, depending on a venue’s ventilation system, indoor air quality levels can approach outdoor levels.
>200 1 Mile
Because they involve strenuous activity for prolonged periods of time, all outdoor activities (practice and competition) shall be canceled or moved to an area with a lower AQI. Move practices indoors, if available. Be aware that, depending on a venue’s ventilation system, indoor air quality levels can approach outdoor levels.

Schools may also refer to OHA’s fact sheet regarding School Outdoor Activities During Wildfire Events at https://apps.state.or.us/Forms/Served/le8815h.pdf. NOTE: While OHA’s guidelines do allow for light outdoor activities in the orange level, the intensity and duration of high school practices/competitions are not considered light activity.
