In the event that the wildfires in Canada are effecting air quality at Pennsic, I have consulted with the KEMs of the East and the Middle. After some discussion, this is what we have come up with.
We are looking at fine particulate matter in the air ( PM2.5) which is measured in the Air Quality Index (AQI). Current measurements can be found at: https://fire.airnow.gov/ At 100 AQI ( PM 2.5 ) asthmatics and sensitive persons will begin having issues by higher degree. At 150 AQI ( PM 2.5) non- sensitive people will begin having issues. At 200 AQI ( PM 2.5) pretty much everyone will be in a dangerous situation. When the local AQI (PM 2.5) is over 200 outdoor martial activities are to be cancelled. At lower levels participants should act with caution and in the interest of their health. As always, Local Marshals may cancel official activities based on their reading of the environment. Additional information can be found at: https://www.airnow.gov/aqi/aqi-basics/
