Wildfires Turn Air Toxic In Western U.S.

Wildfires across several states and Canada are leading to air quality alerts and evacuation orders in the western United States. As of Wednesday, the National Interagency Fire Center reported 79 large, active wildfires that have scorched more than 1.4 million acres. States like California, Oregon, Arizona, and Washington are experiencing significant smoke and haze due to these fires.

In the Northwest, evacuation orders have been issued for 15 active fires, according to the Associated Press. Meanwhile, Canada is also grappling with the fire crisis, with about 430 active wildfires in British Columbia and 177 in Alberta. These fires have led to the evacuation of up to 25,000 people from Canada’s largest national park in the Canadian Rockies.

To address the smoke pollution, air quality alerts have been issued in several areas of the western United States. The Oregon Department of Environmental Quality has warned residents in eastern counties like Harney, Malheur, Grant, Baker, and Morrow. In Idaho, similar advisories are in place for central counties including Ada, Canyon, Gem, Owyhee, Payette, and Washington. In Washington, areas including the Colville Reservation, Chelan County, and the Methow Valley are under alert. Additionally, Calgary in Alberta has received an air quality advisory due to wildfire smoke.

To protect themselves, residents should monitor local air quality conditions and forecasts. Those with air conditioning should regularly change filters, preferably using high-efficiency ones designed to trap smoke particles. Portable air purifiers can also be beneficial. During periods of poor air quality, staying indoors with closed windows and doors is advisable. For those who must be outside, using a respirator mask such as an N-95 or P-100 can provide some protection. Children and individuals with heart or lung conditions may be more affected by unhealthy air.

When cleaning up ash from wildfires, it is important to wear protective gear including goggles and a snug respirator mask. To minimize skin contact with ash, use gloves, closed-toe shoes, socks, and long clothing. For cleaning, mist floors with water before sweeping or mopping, then dispose of the ash in plastic bags. Wash ash off pets and outdoor items, such as vehicles and toys, to prevent further exposure.
