Montreal weather: Air quality advisory issued because of smoke from Western wildfires
Smoke from wildfires in the Prairies has led Environment Canada to issue a special air quality warning.
The federal agency notes that poor air quality and reduced visibility are expected Friday and possibly Saturday.
People most likely to suffer health effects from air pollution include those who are 65 and older; pregnant; infants and young children; people with an existing illness or chronic health conditions and people who work outdoors.
Strenuous activities outdoors should be avoided. People should seek medical attention if serious symptoms manifest. Serious but less common symptoms include wheezing, chest pains or severe cough. Milder symptoms include eye, nose and throat irritation, headaches or a mild cough.
As smoke levels increase, health risks increase., the advisory notes. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events. When indoors, keep windows and doors closed as much as possible.
Measures to protect your indoor air from wildfire smoke include using a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner that can filter fine particles.
If you must spend time outdoors, a well-constructed, well-fitting and properly worn respirator (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke. Even though exposure may be reduced, there can still be risks to health.
Check in on others who are in your care or live nearby who may be more likely to be impacted by outdoor air pollution and always follow guidance from local authorities.
