LAS VEGAS (FOX5) — Clark County’s Division of Air Quality issued a season-long advisory for ground-level ozone and wildfire smoke that will run from April 1 through Sept. 30.
Forecasters say wildfire smoke drifting into Southern Nevada can worsen air quality by increasing particulate pollution and contributing to ozone formation.
The agency reported 18 days last year when ground-level ozone exceeded the U.S. Environmental Protection Agency’s health standard, down from 25 days in 2024. The EPA says ozone exposure can irritate the lungs and cause coughing, sore throat, chest pain and shortness of breath.
Clark County is also issuing a seasonal wildfire smoke advisory for the fourth year in a row, citing more frequent summer wildfires in the West.
The EPA says those most at risk during poor air quality include people with respiratory or heart conditions, young children and older adults. Officials advise anyone with health concerns to consult a doctor about air-quality sensitivity.
SMOKE AND OZONE SAFETY TIPS
- Stay indoors when you smell or see smoke.
- Limit outdoor activity and exertion when ozone levels are elevated.
- Keep windows and doors closed. Run your air conditioner inside your house and car.
- Change your indoor air filters if they are dirty.
- Schedule activities for the morning or evening when ozone levels are usually lower.
- Always consult your doctor first for medical advice.
TIPS TO REDUCE OZONE
Because exhaust from cars, trucks and other vehicles are major contributors to ozone:
- Reduce driving – combine errands into one trip.
- Don’t idle your car engine unnecessarily.
- Use public transportation or carpool.
- Fill up your gas tank after sunset. Try not to spill gasoline when filling up. Don’t top off your tank.
- Keep your car well maintained.
- Consider landscaping that uses less water and gas-powered equipment to maintain.
- Turn off lights and electronics when not in use. Less fuel burned means cleaner air.
