An official recommendation to wear a mask to protect yourself from wildfire smoke is being echoed by health experts as plumes of smoke make their way across parts of Canada, causing poor air quality.
As wildfires continue to burn in several provinces, smoky skies across parts of the country are prompting recommendations from health officials to wear face masks to avoid inhaling harmful smoke.
Health Minister Jean-Yves Duclos told reporters on Wednesday morning that he was feeling the impacts of the smoky air and encouraged people, especially those with pre-existing respiratory conditions, to wear an N95 mask.
“So, for all of these people, including others that may want to protect themselves against the bad consequences of bad quality air, wearing an N95 mask is the recommended procedure by health authorities," Duclos said on Wednesday.
He noted while wearing a mask is a personal choice, he still recommends Canadians wear one if they're outdoors, as the air quality is among the worst in the world.
“But we also know that these consequences will be worse, as the extent of the bad air quality continues. We are told by firefighters and other health officials that, unfortunately, the situation will continue for a few more days.”
As of Wednesday evening, several major cities across the country are reporting a moderate- to high-risk on the Air Quality Health Index including Vancouver, Edmonton, Saskatoon, Regina, Toronto and Ottawa. What's especially harmful about the current air quality in most regions are the extremely small particles—called fine particulates—that can travel into the lungs when we breathe, explains Joe Fida, CIO of Canadian air purifier company Blade Air.
"It is generally not healthy because it can cause inflammation, swelling—there's a lot of very adverse effects from it and the other problem is that they stay airborne for a very long time," Fida told CTVNews.ca in a phone interview on Wednesday.
