Air Quality

Wildfire and Air Quality

Wildfire and Air Quality
 

Smoke from wildfires is a significant source of air pollution and can impact air quality in our community even when a fire is miles away.

Anytime you see or smell smoke during a wildland fire, know that local air quality has been compromised.

Wildfire and Health

Smoke is made up of a complex mixture of gases and particles including fine particulate matter (PM 2.5).  These microscopic particles can get into your eyes and respiratory system which can irritate the lungs and lead to a range of symptoms. Symptoms of smoke exposure include:

  • Watering and irritated eyes
  • Coughing
  • Wheezing
  • Difficulty breathing

While smoke can impact anyone, sensitive populations such as children, pregnant women, the elderly, and those with asthma and other respiratory concerns are especially at risk during a smoke event.

How to Prepare for Smoke from Wildland Fire

Because smoke travels, smoke from long-range fires can impact air quality and health even when smoke does not smell and is not visible.  The best way to know your potential risks due to smoke from wildfilres is to be aware of what the air quality is in your area.  Check the Air Quality Index and pay attention to Air Quality Alerts in your area.

The Colorado Department of Public Health and Environment provides Wildfire Smoke Health Advisories and Smoke Outlooks along with more information and resources concerning health risks from wildfires.

What You Can Do to Minimize Impacts from Smoke

  • In your home
  • In your car
    • Close windows
    • Run AC in recirculation mode
    • Change air filters every 20,000-30,000 miles
    • Do your best not to drive in smoky conditions

Frequently Asked Questions

Should I use a mask or respirator during a smoke event?

A mask or respirator may help to reduce exposure during a smoke event. It is important to learn how to protect your lungs from wildfire smoke or ash. 

Other considerations: 

  • Do not rely on dust masks or bandanas during a smoke event. These are not effective in reducing fine particles that you are breathing in
  • If you feel the need to use a mask during a smoke event, consider N95 or P100 Respirators
  • Even with a mask during a smoke event, it is a good idea to limit activities outside
When should I limit my outdoor activities?

While it is an individuals’ choice on when to limit activities, once air quality values approach moderately high, you may be affected and should consider limiting your activities. Learn more about the Air Quality Index levels of health concern.

If there is a fire close by should I consider evacuating?

Sign up for NOCO Alerts to be aware of evacuation alerts in your area.
