SITUATIONAL AWARENESS: WILDFIRE SMOKE
Wildfire smoke from northern Minnesota and southwestern Ontario is affecting air quality and visibility across Wisconsin, including Lincoln County. Conditions can change quickly as winds move smoke into or out of the area.
Wildfire smoke contains fine particulate matter known as PM2.5. These microscopic particles can travel deep into the lungs and may enter the bloodstream.
Short-term exposure may cause:
• Burning eyes or throat irritation
• Coughing, wheezing, or shortness of breath
• Headaches, fatigue, or reduced exercise tolerance
• Worsening asthma, COPD, or other respiratory conditions
• Increased risk of serious cardiovascular events in vulnerable individuals
Most healthy adults recover quickly, but wildfire smoke is not harmless. Repeated or prolonged exposure may affect lung function and increase the risk of respiratory illness. Research into other potential long-term effects remains ongoing.
Children, older adults, pregnant women, people with heart or lung conditions, outdoor workers, and anyone spending extended time outside should take additional precautions.
Simple actions residents and visitors can take:
• Monitor the Air Quality Index and local alerts before outdoor activities.
• Reduce strenuous outdoor activity and move activities indoors when possible.
• Keep windows and doors closed and set air conditioning to recirculate.
• Use a properly sized portable air cleaner or a MERV 13 HVAC filter if your system can accommodate it.
• Keep vehicle windows closed and use the recirculate setting.
• When outdoor exposure cannot be avoided, wear a properly fitted NIOSH-approved N95 or P100 respirator. Cloth face coverings do not provide reliable protection from wildfire smoke.
• Do not remain in a dangerously hot home simply to keep the windows closed. Seek an air-conditioned location with cleaner air when necessary.
Seek medical attention for severe difficulty breathing, chest pain, confusion, fainting, or symptoms that are rapidly worsening.
Smoke can travel hundreds of miles from the fire itself. You do not need to see flames for wildfire smoke to affect your health.
Be aware. Limit your exposure. Check on family members, neighbors, and others who may need assistance.
