Smoke from wildfire triggers ‘unhealthy’ air quality alert for Las Vegas Valley through Sunday

LAS VEGAS (KLAS) – An air quality alert for smoke and ozone is in effect for Clark County through Sunday. According to the Clark County Department of Environment and Sustainability (DES), “unhealthy smoke levels” from wildfires in northern California are drifting and looming over the Las Vegas Valley.

Exposure to ozone can cause coughing, wheezing, and shortness of breath, even in healthy people. However, residents with breathing problems, heart disease, young children, or the elderly should monitor outdoor activity, check air quality readings, and seek medical attention if they are sensitive to high levels of air. particulate matter and ozone.

DES explained that smoke is made up of tiny particles of dust and other pollutants that worsen respiratory illnesses and contribute to the formation of ground-level ozone.

The seasonal ozone advisory went into effect on Saturday as smoky conditions were expected throughout the day.

  • Stay indoors when you smell or see smoke.
  • Limit outdoor activities and exertion when ozone levels are high – exercise makes you breathe harder and increases the amount of particles you can inhale.
  • Keep windows and doors closed. Operate your air conditioner inside your home and in your car. Air conditioning filters smoke and particles.
  • Change your indoor air filters if they are dirty.
  • Schedule activities in the morning or evening when ozone levels are generally lower.
  • Replace yourself with less strenuous activity – walking instead of running, for example.
  • Reduce driving – combine errands into one trip.
  • Don’t idle your car unnecessarily.
  • Use public transport or carpooling.
  • Fill your gas tank after the sun goes down. Try not to spill gasoline while filling and don’t fill your tank.
  • Keep your car well maintained.
  • Consider landscaping that uses less water and gas powered equipment for maintenance.
  • Turn off lights and electronics when not in use. Less fuel burned in power plants means cleaner air.
