Do Your Share For Cleaner Air


The University participates in a program to voluntarily help reduce the generation of ozone during periods that unhealthy levels are predicted. We do this by communicating information about how to reduce emmissions which lead to ozone production and urge people to take these precautions.


For example:

Limit daytime driving and combine errands

When you must drive, try to avoid congested periods

Ride public transportation or carpool to work

Maintain your vehicle's emission control equipment

Walk or ride a bicycle for short, easy trips

Postpone the use of gasoline-powered mowers until evening

Refuel your car in the evening - and don't "top off" your tank

Avoid lighting your barbeque with starter fluid

Avoid prolonged idling and jackrabbit starts

Use latex rather than oil-based paints

  • Research shows that prolonged exposure to high concentrations of ground-level ozone can cause lung damage in humans. Like a sunburn on your skin, ozone can "burn" cells in the lung's airways , ultimately leading to permanent lung damage. Young children, the elderly and people with respiratory problems are more at risk to the effects of ground-level ozone and should avoid the outdoors. Even healthy adults exercising outside may experience lung problems on high ozone days.
