An ozone action day means pollutants are expected to be in the “unhealthy for sensitive groups” range. People and businesses are urged to avoid activities which lead to ozone formation. These activities include refueling vehicles or topping off when refueling, using gasoline-powered lawn equipment, and using charcoal lighter fluid.
Positive activities include car pooling, biking to work, delaying or combining errands and using water-based paints.
The DNR recommends that active children and adults, and persons with respiratory diseases such as asthma, limit prolonged outdoor exertion.
