Possible ammonia contamination prompts evacuations after Oregon seafood plant fire, officials say

Evacuations Expanded in Newport After Fire Raises Ammonia Concerns

Activelifezero.com – Emergency crews in Newport, Oregon, continued responding Sunday after a fire at a Pacific Seafood processing facility led officials to warn of a possible ammonia release and order evacuations across a widening area of the coastal city.

By late Sunday morning, the evacuation area had grown to a one-mile radius around the plant. The order affected both commercial waterfront blocks and nearby residential neighborhoods in Newport, a city with a population slightly above 10,000.

“The evacuation is due to a potential ammonia contamination in the area from the plant.”

City officials urged people in Newport to remain indoors when possible. Anyone who needed to leave a building was advised to wear a mask while conditions remained under review. Firefighters were still working to bring the blaze under control, with city-posted video showing crews spraying water onto the facility.

Highest evacuation level issued

The Lincoln County Sheriff’s Office placed the area within one mile of the seafood plant under a Level 3 evacuation notice. That designation is the highest evacuation level and means people in the affected zone should leave immediately.

Authorities also closed a portion of US 20, from Harney Street westward to US 101, and asked the public to avoid the area while emergency activity continued. A shelter for displaced residents and visitors was opened at Sam Case Elementary School.

The initial evacuation boundary covered roughly a half-mile area around Newport’s Bayfront district. The waterfront area includes businesses and visitor attractions, but it has comparatively few homes. Once the perimeter was enlarged, it reached residential sections closer to the processing plant.

Although autumn is outside Newport’s busiest tourism period, the city continues to receive weekend visitors. The evacuation and road restrictions therefore affected not only residents but also people who may have been visiting restaurants, shops and attractions near the waterfront.

Workers accounted for, no injuries reported

Pacific Seafood said all of its employees had been accounted for and that it was not aware of any injuries. The company said its immediate focus was assisting emergency responders as they worked to protect people in and around the facility.

“However, the situation is still ongoing and we are focused on supporting emergency responders to help ensure everyone is safe.”

City spokesperson John Fuller said there had been no reported injuries as of Sunday morning. He estimated that hundreds of people had evacuated after officials expanded the emergency zone.

Investigators had not yet determined what caused the fire or whether ammonia had escaped from the plant. Those questions remained central as fire crews continued operations and officials monitored conditions in the surrounding area.

Smoke seen over waterfront area

Videos recorded in Newport showed a heavy plume of smoke rising above the city. Oregon resident Coby Bertalotto described difficult driving conditions after encountering the smoke near the waterfront.

“Driving through that thick smoke … It was thick enough that I couldn’t see the side of the road.”

Bertalotto said he proceeded carefully and noticed a “rubbery” odor outdoors. He described several blocks near tourist-oriented businesses, including candy stores, bars and Ripley’s Believe It or Not, as being heavily affected by smoke.

“There are probably about three or four blocks that are just getting smoked out.”

Smoke conditions can shift quickly with wind and firefighting activity, which helps explain why officials asked the public to stay away from the scene. People outside the evacuation area were also encouraged to limit unnecessary time outdoors while the potential hazard was being assessed.

Why ammonia warnings matter

Ammonia is commonly used in industrial refrigeration systems, including some food-processing operations. In high airborne concentrations, it can irritate the skin, eyes, throat and lungs. Possible effects include coughing and burns, and people with asthma may be especially sensitive.

That risk is why emergency officials treated the possibility of contamination as a public-safety concern even before a release was confirmed. Leaving the designated area promptly, staying inside when directed and keeping clear of closed roads can help responders work without added traffic or exposure risks.

Residents within the evacuation boundary were instructed to follow local emergency directions rather than return for belongings or attempt to travel through the restricted zone. Anyone needing assistance could use the shelter established at Sam Case Elementary School.

The situation remained active Sunday, with authorities continuing to evaluate the fire, air-safety concerns and the scope of the evacuation. Further updates were expected as crews completed their response and investigators examined the seafood plant incident.
