Tips to reduce ozone pollution:

  • Drive less. When possible, carpool, van pool or use public transportation
  • Avoid waiting in long drive-thru lines, for example, at coffee shops, fast-food restaurants or banks. Park your car and go inside
  • Re-fuel your vehicle in the early morning hours or after dark during cooler hours
  • Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers
  • Delay big painting projects until high pollution advisories have passed
  • Make sure that containers of household cleaners, garage and yard chemicals and other solvents are sealed properly to prevent vapors from evaporating into the air
  • Conserve electricity

 

Tips to reduce dust pollution:

  • Use a rake or a broom instead of using a leaf blower.
  • Avoid using gas-powered lawn and garden equipment
  • Avoid using woodburning fireplaces or stoves on no burn days
  • Drive slowly or not at all on unpaved roads and vacant lots
  • Avoid driving off-road vehicles in the dirt or on unpaved roads
  • Consolidate errands into one trip
  • Conserve electricity

"High Pollution Advisory" or "HPA" means the highest concentration of pollution may exceed the federal health standard. Active children, adults and people with lung disease such as asthma should reduce prolonged or heavy outdoor exertion. Maricopa County employers enlisted in the Trip Reduction Program are asked to activate their HPA plans on high pollution advisory days.


"Health Watch" means the highest concentration of pollution may approach the federal health standard. Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion during a health watch.
