<strong>What you can do:</strong> </p><ul style="list-style-type:disc;"><li>
<strong>Check in on others</strong> who may be more affected. People at higher risk include those with lung, heart or other chronic conditions, pregnant people, infants, children, older adults, and outdoor workers.</li><li>
<strong>Improve indoor air quality.</strong> Use portable HEPA air cleaners or do-it-yourself box fan air cleaners. If your home has a built-in ventilation system, install filters rated MERV 13 or higher to remove smoke. If possible, adjust the ventilation system to reduce smoke coming indoors.</li><li>
<strong>Keep windows and doors closed while running air filtration.</strong> If it's hot, focus on staying cool.</li><li>
<strong>Spend time in places with air conditioning</strong> if your home is smoky or too hot. Try community centres, libraries, or malls.</li><li>
<strong>Seek medical help if you experience severe symptoms</strong> such as wheezing, chest pain, trouble breathing or severe cough. Call 911 in emergencies.</li><li>
<strong>Manage chronic conditions</strong> and carry rescue medications with you (e.g. inhalers).</li><li>
<strong>If you must be outside, a well-fitted N95, KN95, or KF94 mask</strong> offers the most protection. Medical masks offer some protection and single layer coverings (e.g. bandanas, scarfs, shirts) offer none.</li><li>
<strong>Check the Air Quality Health Index (AQHI) often</strong> throughout the day because conditions can change quickly. See
