On Wednesday evening, ash could be seen falling from the sky in parts of Calgary
The Air Quality Health Index (AQHI) forecast for the city showed conditions were expected to reach 10+ on the scale Thursday, representing a potentially very high health risk.
On Wednesday evening, ash could be seen falling from the sky in parts of Calgary.
For those who must spend time outdoors, it is recommended to use a well-constructed, well-fitting and properly worn respirator-type mask to reduce exposure to the fine particles in the smoke, said Environment Canada in its air quality advisory.
“Consider rescheduling or cancelling outdoor sports, activities and events,” the weather service said.
Symptoms of exposure to smoke can include milder and more common symptoms such as eye, nose and throat irritation, as well as serious but less common symptoms such as chest pains or severe cough.
“Listen to your body and if you experience symptoms, reduce or stop outdoor activities,” Environment Canada said. “If you think you are having a medical emergency, seek immediate medical assistance.”
When indoors, keep windows and doors closed if possible, its statement said.
