PHOENIX — Environmental regulators have issued an ozone health watch
Friday in metro Phoenix as the area’s pollution levels may approach the federal
health standard for air quality.
Officials said people who are unusually sensitive to air quality should consider
limiting their time outdoors, because ozone can irritate the lungs and aggravate
existing health conditions such as asthma.
Authorities recommended that people avoid waiting in their cars at drive-thru
restaurants, unplug electronic devices and appliances that aren’t being used, and fuel their cars after dark or during cooler evening hours.
