Air Quality Alerts and Advisories

Unhealthy air pollution from wildfire smoke has triggered air quality alerts across the western U.S. and Canada.

- Washington: The Colville Reservation and Chelan County are under air quality alerts.
- Canada: An advisory was issued for Calgary, Alberta, due to high-risk wildfire smoke.
Impact on Las Vegas
Las Vegas has not been spared from the impact of these widespread wildfires. The smoke has significantly degraded air quality, prompting health advisories. Residents are advised to limit outdoor activities, particularly vulnerable groups such as children and the elderly.
Safety Measures for Dealing with Wildfire Smoke
To protect yourself from wildfire smoke, consider the following tips:
- Monitor Air Quality: Stay informed about air quality conditions and forecasts in your area.
- Stay Indoors: Keep windows and doors closed to minimize indoor pollution.
- Use Air Purifiers: High-efficiency filters labeled “MERV13” or higher are effective in removing smoke particles. Portable HEPA air purifiers can also help.
- Avoid Outdoor Activities: Limit heavy exertion outdoors and avoid activities that increase indoor pollution, such as burning candles or using wood-burning appliances.
- Wear Masks: If you need to be outside, use an N-95 or P-100 respirator mask for some protection.
Cleaning Up After a Wildfire
When cleaning ash after a wildfire, wear protective gear, including goggles and an N-95 or P-100 mask. Avoid skin contact with ash, and use gloves, closed-toe shoes, socks, and long pants and shirts. Clean ash from pets and outdoor belongings, mist floors with water before sweeping, and avoid using leaf blowers. Dispose of ash properly and avoid letting contaminated water enter storm drains.
The ongoing wildfires in the western U.S. and Canada are causing significant air quality issues, affecting millions of people, including those in Las Vegas. As the fires continue to burn, it is crucial to stay informed and take necessary precautions to protect your health and safety. With climate change exacerbating these fire conditions, it’s more important than ever to be prepared and vigilant.
