A special air quality statement issued for Calgary on Tuesday evening due to wildfires burning throughout the province had ended just after 3:30 p.m. Wednesday.
The statement, issued by Environment Canada at around 10:30 p.m., warned smoke was causing poor air quality and reducing visibility in Calgary and areas south of the city.
Calgary’s current Air Quality Health Index (AQHI)
By 12 p.m. on Wednesday, Alberta Environment and Parks listed Calgary’s Air Quality Health Index (AQHI) at 4 (moderate risk), with it forecast to sit at 4 throughout the day.
By 3 p.m., it had decreased to a 3 (low risk).
Precautions to take amid potential health concerns
Symptoms such as increased coughing, throat irritation, headaches or shortness of breath may be experienced due to the smoke. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk during such incidents.
According to the AHS website, when an air quality advisory is in effect, all individuals living in or travelling within the affected area are advised to take the following precautions to reduce exposure and risk:
- If air quality is because of smoke reduce presence of smoke in indoor environments:
- Close and lock all outside windows and doors, including attached garage doors.
- Turn down furnace thermostats and furnace fans to the minimum setting. Do not attempt to extinguish pilot light.
- If you have an air conditioner, keep the fresh-air intake closed and the filter clean to prevent outdoor smoke from getting inside.
- Avoid running fans, such as “whole-house fans” or “fresh air ventilation systems,” that bring more smoky outdoor air inside.
- Switch all floor registers to closed position.
- Close fireplace dampers on wood-burning fireplaces.
- Do not use wood burning fireplaces, wood stoves or other smoke-producing appliances or features, including candles.
- If you must drive to another location, keep windows and vents closed. Run car fans on recirculate mode to avoid drawing in outdoor air.
- Reduce levels of physical activity, as necessary, to decrease the inhalation of airborne pollutants.
- Do not smoke tobacco – smoking puts added stress on your lungs and those around you.
- Residents are reminded not to use backyard fire pits or fire boxes in parks when the air quality risk is high or very high.
- If air quality is because of smoke reduce presence of smoke in indoor environments:
Individuals with respiratory conditions (such as COPD and asthma), and individuals with existing cardiovascular conditions (such as angina, previous heart attack and congestive heart failure), may notice a worsening of symptoms. These individuals should take the precautions routinely recommended by their physicians if a worsening of symptoms occurs.
Children and elderly are also at higher risk of smoke-related illness.
