Special air quality statement in effect for:

Poor air quality over Southern and Central Alberta.

Forest fire smoke drifting in from the Northwestern United States is reducing visibilities and creating poor air quality over much of Southern and Central Alberta.

Areas around Edmonton and Central Alberta as well as near the U.S. border are most likely to be affected by the smoke and lower air quality today, tonight and tomorrow.

Today air quality health index values are not expected to be as high as earlier in the week over much of Southern Alberta however, the fires continue to produce large amounts of smoke and the atmospheric flow pattern remains similar to last week so it is possible that elevated air quality values will return over the next few days.

Individuals living in or travelling in this area are advised to be aware of potential health concerns that can be associated with current air conditions. In the current conditions, even healthy individuals may experience temporary irritation of eyes and throat, and possibly shortness of breath.

To reduce exposure to the current air conditions, all individuals can: 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 fire place dampers on wood burning fireplaces.

Do not use wood burning fireplace, 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 re-circulate 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, as it is now.

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, due to the current air conditions.

These individuals should monitor for worsening of symptoms and 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.

Individuals experiencing symptoms can also call health link at 811 to speak to a registered nurse.

Air quality can vary with weather conditions and prevailing winds. Because air quality is expected to be variable, this advisory will remain in effect until further notice.
