July 31, 2018 - 2:53 pm

LAS VEGAS (KXNT) - Combine smoke from wildfires burning in California and Arizona, with ozone, and it leads to Clark County issuing an air quality advisory through Wednesday.

Clark County’s Department of Air Quality (DAQ) is issuing an advisory for Tuesday, July 31 – Wednesday, Aug. 1. Elevated levels of smoke and ozone are forecast for southern Nevada, due to wildfires in California and Arizona, Air Quality officials said. Smoke is comprised of small dust particles that can contribute to ground-level ozone formation.

According to the U.S. Environmental Protection Agency, people who may be most sensitive to elevated levels of particles and ozone include individuals with respiratory problems, cardiac disease, young children or senior citizens. Consult your physician if you have a medical condition that makes you sensitive to air quality conditions.

Exposure to ozone can induce coughing, wheezing and shortness of breath even in healthy people. A seasonal ozone advisory is currently in effect.


*Stay indoors when you smell or see smoke.

*Limit outdoor activity and exertion when ozone levels are elevated – exercise makes you breathe heavier and increases the amount of particulates you may inhale.

*Keep windows and doors closed. Run your air conditioner inside your house and car. Air conditioning filters out smoke and particles.

*Change your indoor air filters if they are dirty.

*Schedule activities for the morning or evening when ozone levels are usually lower.

*Substitute a less intense activity – walk instead of jog, for example.

*Reduce driving – combine errands into one trip.

*Don’t idle your car engine unnecessarily.

*Use mass transit or carpool.

*Fill up your gas tank after sunset. Try not to spill gasoline when filling up, and 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 at power plants means cleaner air. 


The Department of Air Quality monitors air pollution through a network of monitoring sites throughout the Las Vegas Valley. Data is collected from these sites and reported at our monitoring website:
