Residents and businesses near an Interstate 95 truck stop in Kenly were evacuated for several hours after a leak was discovered on a tanker truck hauling a pungent gas.
Officials lifted the evacuation about 2 p.m. Wednesday after a leaking valve on the truck was repaired at the truck stop. Authorities identified the gas as silicon tetrafluoride.
A Web site of the National Oceanic and Atmospheric Administration said the gas is colorless, nonflammable and corrosive, and can be fatal if inhaled.
Johnston County spokeswoman Robin Gurgainus said there were two people in the truck, and one became overcome by fumes. Gurgainus said the person was in stable condition at Johnston Memorial Hospital in Smithfield.
Gurgainus said the truck was hauling 12,500 pounds of the gas from North Carolina to Texas.
