A malfunctioning relief valve caused an ammonia leak at a turkey plant in Adams County, PA, which led emergency responders to issue a shelter in place notice Saturday for three municipalities.
The shelter in place call went into effect at 5:45 p.m. and lasted for an hour. The notice affected New Oxford, Oxford Township and Hamilton Township.
The leak came from a turkey plant, fire officials said. The leak came from a relief valve from the roof of the building, according to the release.
The leak has been blamed on recent high temperatures. The gas leaked from the refrigeration system at Plainville Farms in New Oxford.
There were no injuries in the incident.
