Hazardous Air Quality - “Everyone should stay indoors and reduce activity levels.”
The DC region has blown past the expected Code Red Air Quality warning for Friday, July 18. It was only red for about an hour before moving to the purple “Very Unhealthy” for everyone range. Now, it’s mostly in the maroon “Hazardous” for everyone range, which is the highest this scale goes up to. This is due to wildfire smoke from Canada. Good thing rain is in the forecast for tomorrow.
If you have an N95 mask, such as the 3M Aura (which fits about 80% of adults), it is a very good idea to wear it. Under these conditions, a half piece respirator is better if you have one and need to go outdoors. Most hardware stores should have them in stock if you don’t have one on hand.
Remember that smoke rises, so stay on the lowest floor while indoors if you can. The PM levels for my upstairs rooms are much higher than my lower ones. You can seal leaky windows with painters tape and plastic sheeting to create a “safe room” with HEPA air purifiers or make a CR Box (I reposted a tutorial yesterday).

'Dangerous' air quality in Detroit, Minneapolis as thick wildfire smoke shrouds the sky for millions
Smoke from wildfires burning in Ontario have caused air quality to reach "dangerous" levels across Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve.

" Massive plumes of smoke are descending across parts of Canada and the United States, creating dangerous air quality and scenes reminiscent of the historic wildfire smoke outbreak from three summers ago.
" 'In 2023, a major fire outbreak in Quebec caused days of unhealthy air quality in the northeastern U.S.,' AccuWeather Vice President of Forecast Operations Dan DePodwin said. 'This event could cause similar levels of poor air quality in spots.'
"Air quality alerts have been issued for millions of people, including across all of #Connecticut, #Delaware, #Massachusetts, #Michigan, #NewHampshire, #NewJersey, #NewYork, #Ohio, #Pennsylvania, #RhodeIsland and #Wisconsin.
"Over 800 wildfires are currently burning across Canada, including dozens that are out of control across western #Ontario, the source of most of the smoke. 'Many of these fires may have been started by lightning,' AccuWeather Senior Meteorologist Brett Anderson said.
"On Wednesday, #Toronto had some of the worst air quality in North America, reaching 'very unhealthy' levels with an AQI of 220. #BostonMA was not far behind with an unhealthy AQI of 147.
" 'When the AQI climbs into the 150+ range for a full day outside, that’s in the ballpark of [smoking] 7 to 9 cigarettes,' Dr. Jonathan M. Tan, division chief of General Anesthesiology at Children’s Hospital of Philadelphia, told AccuWeather.
"Conditions deteriorated by Thursday morning, with widespread "dangerous" air quality across nearly all the Great Lakes region and into parts of the Northeast. Minneapolis and Duluth, Minnesota, as well as Detroit, were among the worst cities at daybreak Thursday, with AQIs over 340.
" 'Any exposure to the air, even for a few minutes, can lead to serious health effects on everybody,' Plume Labs said.
Avoid outdoor activities.' "#CanadianWildfires #CRBox #AirQuality
