Smoke is causing or expected to cause poor air quality and reduced visibility. Elevated pollution levels are expected or occurring.
High levels of air pollution due to smoke from forest fires continue. Elevated ground round level ozone are possible today into Saturday.
Smoke plumes from forest fires in northeastern Ontario and Quebec is forecast to return to the area today or tonight. As a result, the air quality is expected deteriorate once again. The poor air quality will likely last into Saturday.
Ground level ozone concentrations may increase today and Saturday.
Air quality and visibility due to wildfire smoke can fluctuate over short distances and can vary considerably from hour to hour.
Wildfire smoke can be harmful to everyone’s health even at low concentrations. Everyone can take action to reduce their exposure to wildfire smoke.
People with lung disease (such as asthma) or heart disease, older adults, children, pregnant people, and people who work outdoors are at higher risk of experiencing health effects caused by wildfire smoke. Speak with your health care provider about developing a management plan for wildfire smoke events and maintaining a supply of necessary medications at home and always carrying these medications with you during wildfire season.
Stop or reduce your activity level if breathing becomes uncomfortable or you or someone in your care feel unwell. Contact your health care provider or local health authority if you develop severe symptoms or need advice.
Check the Air Quality Health Index (AQHI) and monitor your symptoms. People respond differently to smoke. Mild irritation and discomfort are common, and usually disappear when the smoke clears. Drinking lots of water can help your body cope with the smoke.
If you have an HVAC system in your home, use the highest rated MERV filter for your system (ideally rated 13 or higher) and set the fan to recirculate air constantly. You can also use a portable High Efficiency Particulate Air (HEPA) air cleaner. Keep your doors and windows closed if the temperature in your home is comfortable.
Take a break from the smoke at a location in your community where you can find clean, cool air.
If you must spend time outdoors, a well-fitted respirator type mask (such as a NIOSH certified N95 or equivalent respirator) that does not allow air to pass through small openings between the mask and face, can help reduce your exposure to the fine particles in smoke. These fine particles generally pose the greatest risk to health. However, respirators do not reduce exposure to the gases in wildfire smoke. It is important to listen to your body and reduce or stop activities if you are experiencing symptoms.
Be sure to check on people in your care and those around you who may be more susceptible to smoke.
Reduce sources of indoor air pollution. If you can, avoid smoking or vaping indoors, burning incense and candles, frying foods, using wood stoves and vacuuming. Dust on indoor surfaces can be removed by wiping and wet mopping during a pollution episode. ...read more
