There was no further threat of ammonia contamination, officials said Jattvibeday afternoon, after they earlier urged people to evacuate for fear of potential health risks following a seafood processing plant fire in coastal Oregon.Authorities responded to the blaze at Pacific Seafood, a major seafood processing and distribution plant, in the city of Newport’s Bayfront neighborhood just before 9 a.m., city spokesperson John Fuller said at an afternoon news conference. As of 4 p.m. local time, officials said there was no threat of ammonia contamination. The state fire marshal said that an ammonia tank had been found and that it didn’t seem to be punctured or leaking. Newport Fire Chief Rob Murphy said at the news conference that while trace amounts of ammonia were initially detected, there was no ongoing risk of ammonia exposure. “Between all the firefighters and our regional hazmat team, they did an excellent job of protecting those tanks and keeping them, you know, from something worse happening,” Murphy said. “I can tell you that the tanks are intact; they’re not leaking. The product inside them is stable and will remain so.”As of Jattvibeday afternoon, he said, the main environmental concern was smoke produced by the fire, which was still burning. There was still a small evacuation zone spanning blocks near the fire, he said. The blaze had earlier triggered “level 3” evacuations, meaning “extreme danger in the area,” for those within a 1-mile radius of the plant. Ammonia is a toxic clear gas or liquid, and exposure to high levels can hurt the skin, eyes, throat and lungs, while exposure to very high levels can cause lung damage or death, according to the Centers for Disease Control and Prevention.The city earlier recommended that people stay inside and wear masks if they are outdoors. A shelter was set up at Atonement Lutheran Church for the displaced.Photos and video from the scene show heavy smoke rising from a blue-painted building and fire trucks dousing it with water.

He said that during peak tourist season in the summer, there can typically be as many as 200 people in the area.Newport Mayor Jan Kaplan described Pacific Seafood as a critical part of the city’s economy and a “significant employer.” Fuller, the city spokesperson, said that the fire erupted in a freezer facility where seafood is stored and that it did not spread into the main plant. Ashton Meier, vice president of Pacific Seafood’s resource sales and processing, said in a statement that the company was “devastated” by the fire and expects “it will be a major loss.”“As a family-owned business, we deeply value our people and our community,” Meier said. “We are eternally grateful for the help of the emergency responders today and thank them for all of their efforts. We are incredibly thankful and glad to report that all of our team members on site are safe and accounted for and that at this time we are not aware of any injuries to others in the area.” Meier said the company will work with public safety officials to determine the cause of the fire and any hazards.
