ELLINGTON, Conn. (AP) -- A leak at a juice company sent a cloud of ammonia over town early Tuesday, leading to the evacuation of about 1,000 people.
The leak from a tank was reported about 2 a.m. at the Natural Country Farms plant and wasn't plugged until around seven hours later, officials said.
The leak developed after a 2-inch pipe flange came loose in an area where 8,000 gallons of anhydrous ammonia, used as a refrigerant, is stored, fire officials said. Crews in chemical protection suits were sent in to stop the leak.
``It's going to clean itself up once we ventilate,'' Assistant Fire Chief Gary Feldman said. ``It's not like an oil spill, where we've got a bunch of gunk to clean up. It's just going to dissipate.''
Environmental tests found that even in areas of heavy concentrations of the ammonia, the gas didn't reach a level considered dangerous, officials said.
Earlier, police knocked on doors in this northeastern Connecticut town to notify people of the leak. About 1,000 people left their homes; some decided to stay and were allowed to do so.
Among the evacuees were Diana Gamage and her two children, age 15 and 12.
``I thought the house was on fire. I opened the door and saw all the firefighters standing there. That's the first thing I thought,'' Gamage said.
One plant employee was taken to a hospital for treatment and four residents with pre-existing medical conditions were taken to hospitals as a precaution, Feldman said.
The state Department of Environmental Protection had people at the scene and the U.S. Environmental Protection Agency had been notified, he said.
