A special air quality statement is in effect for the City of Lethbridge.
According to Environment and Climate Change Canada, wildfire smoke is causing, or is expected to cause, poor air quality and reduced visibility. The agency said conditions are expected to improve in most areas by the weekend, but smoke levels and visibility can change quickly over short distances and from hour to hour.
Officials urge residents to scale back outdoor activities as smoke concentrations rise, particularly when air quality deteriorates. They also encourage people to reduce or reschedule outdoor sports, activities and events. Health officials said people may experience mild symptoms, including eye, nose and throat irritation, headaches or a mild cough. Less common but more serious symptoms include wheezing, chest pain or a severe cough. Anyone experiencing a medical emergency should seek immediate medical attention.
Seniors, people who are pregnant, infants and young children, people with existing illnesses or chronic health conditions and outdoor workers are encouraged to reduce or reschedule strenuous outdoor activities because they are at greater risk from wildfire smoke.
Anyone who develops symptoms is encouraged to seek medical attention.
People can reduce the amount of smoke entering their homes by keeping windows and doors closed whenever conditions allow, while ensuring indoor temperatures remain safe during periods of extreme heat. Officials also recommend using high-quality air filters or certified portable air cleaners where possible.
Anyone who must spend time outdoors is advised to wear a well-fitting respirator, such as a NIOSH-certified N95 or equivalent, to reduce exposure to fine smoke particles, although some health risks may remain.
Residents are also encouraged to check on neighbours and others who may be especially vulnerable to wildfire smoke and to follow guidance from local authorities.
The advisory was issued by Environment and Climate Change Canada, Alberta Environment and Protected Areas, Alberta Health and Alberta Health Services.
