Environment Canada has again issued caution for residents in Eastern Ontario and Western Quebec Friday as wildfire smoke continues to cause health problems and reduced visibility on roadways.
“Wildfire smoke is expected over the area this morning into early afternoon,” the agency said in a statement at 4:30 a.m.
“As smoke levels increase, health risks increase.”
Shortly before 7 a.m., the federal Air Quality Health Index show Ottawa air quality at “10-High Risk.” That status is expected to continue through the day, slipping to “7-High Risk” Friday evening and overnight.
Officials continue to ask residents to try to limit outdoor activities.
Residents may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough.
People more likely to be impacted by outdoor air pollution include people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors.
The forecast for Friday is for a high of 26 C, with a mixture of sun and clouds through the day. The humidex level is expected to be about 28, while the UV index is expected to hit 8, or “very high.”
Local smoke is in the forecast for most of the weekend.
Residents are asked to try to
keep windows and doors closed as much as possible.
“Protect your indoor air from wildfire smoke.
“Actions can 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 outdoor travel is unavoidable, a well-constructed, well-fitting and properly worn respirator-type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce exposure to the fine particles in the smoke.
Even though exposure may be reduced, there can still be health risks, officials say.
