Oregon coastal city issues evacuation order after fire at seafood plant

The city of Astoria, Oregon, has ordered the evacuation of residents and workers in the vicinity of a fire that broke out early Wednesday morning at the Pacific Harvest seafood processing plant, authorities said. The blaze, which ignited at approximately 04:30 local time in the plant’s refrigeration section, quickly spread to adjacent storage areas and prompted a rapid response from the Astoria Fire Department, the Oregon State Fire Marshal’s Office and emergency medical services. Officials warned that the fire’s intensity and the potential release of hazardous chemicals, particularly ammonia used in the plant’s cooling systems, could pose a serious health risk to the surrounding community.Emergency crews arrived on the scene within minutes of the first 911 call and deployed a combination of water hoses and foam to contain the flames..

Despite the swift action, the fire persisted for over three hours, prompting the fire marshal to declare a “major incident” and request mutual aid from neighboring jurisdictions, including the fire departments of Seaside and Tillamook. By the time the fire was declared under control at 08:15, the structure’s roof had collapsed in several sections, and thick black smoke continued to billow from the building, prompting officials to keep the evacuation order in place as a precautionary measure.The primary concern for health officials centred on the plant’s extensive use of ammonia, a colourless gas with a pungent odor that is commonly employed as a refrigerant in large-scale food processing facilities. Ammonia is highly toxic when inhaled in significant quantities, causing respiratory distress, eye irritation and, in extreme cases, pulmonary oedema..

The Oregon Health Authority’s Hazardous Materials Response Team was dispatched to monitor air quality and conduct on‑site testing for ammonia concentrations. Preliminary readings taken by the team indicated that ammonia levels in the immediate vicinity of the plant were above the state’s emergency exposure threshold, leading to the decision to expand the evacuation radius to a one‑kilometre perimeter around the site.Mayor Dan Gifford addressed the public at a press conference at 10:00, urging residents within the designated zone to remain outdoors and avoid re‑entering their homes until authorities deemed it safe. “Our top priority is the safety of our citizens,” Gifford said, adding that the city’s emergency operations centre was working closely with state and federal agencies to assess the situation and coordinate the response..

He also confirmed that the city’s emergency shelter at Astoria High School had been opened to accommodate displaced families, with provisions for food, water and medical assistance.The evacuation order affected roughly 1,200 individuals, including workers employed at the plant, nearby residents and patrons of the downtown area. The Astoria Police Department set up traffic control points on Highway 101 and the main thoroughfares leading into the city, directing motorists away from the affected zone and providing information on alternative routes. Public transportation services were temporarily suspended, and the local ferry terminal halted operations for the morning, further complicating the logistics of moving people out of the area..

The city’s emergency management team deployed three mobile command units to assist in the coordination of rescue efforts and to disseminate updates via the municipal website and social media channels.In addition to the health hazards posed by potential ammonia exposure, officials raised concerns about environmental contamination. The Pacific Harvest plant sits adjacent to the Columbia River, a critical habitat for salmon and other migratory fish species. The Oregon Department of Environmental Quality (DEQ) dispatched water sampling teams to test for chemical runoff that might have entered the river as a result of the fire..

Early results indicated no detectable levels of ammonia in the river water, but DEQ officials warned that ongoing monitoring would continue for at least 48 hours to ensure the river’s safety for both wildlife and recreational users.Local businesses, many of which rely on tourism and the maritime economy, reported a sudden decline in customer traffic as visitors chose to avoid the area amidst the evacuation. The Astoria Chamber of Commerce issued a statement expressing solidarity with first responders and urging the community to support affected businesses once the situation stabilises. “Our city’s resilience has always been tested by the forces of nature,” the statement read, “and we will emerge stronger together.”The cause of the fire remains under investigation..

Initial speculation suggested a malfunction in the plant’s refrigeration system, which could have ignited a buildup of flammable gases. However, fire investigators from the state marshal’s office have not ruled out other possibilities, including electrical faults or human error. The investigation team has secured the site and is collecting evidence, including surveillance footage, maintenance records and witness testimonies, to determine the origin of the blaze..

The plant’s owner, Pacific Harvest Inc., released a brief comment indicating full cooperation with authorities and pledging to conduct an internal review of safety protocols.Insurance experts note that the incident may have broader implications for the seafood processing industry, which increasingly relies on ammonia refrigeration due to its efficiency and lower environmental impact compared to traditional chlorofluorocarbon systems. “While ammonia is an effective refrigerant, incidents like this underscore the importance of rigorous safety standards and regular training for personnel handling hazardous substances,” said Laura Chen, a risk‑management consultant based in Portland. “Regulators may revisit existing guidelines to ensure that facilities have adequate detection, containment and emergency response measures in place.”As the day progressed, the evacuation order was partially lifted for a small number of households located on the periphery of the exclusion zone, provided that they remained indoors with windows closed and air filtration systems operational..

Residents were instructed to monitor local news broadcasts and the city’s official alert system for further instructions. The emergency shelter at Astoria High School continued to operate, with volunteers from the American Red Cross and local churches providing meals and counseling services to those displaced by the fire.State Governor Tina Kotek, who arrived in Astoria in the afternoon, toured the scene alongside the fire marshal and the health authority’s lead toxicologist. In a televised address, Kotek praised the swift response of first responders and affirmed that state resources would be made available to aid in the recovery effort..

“We will ensure that the people of Astoria have the support they need to rebuild and that we learn the necessary lessons to prevent future tragedies,” she said. The governor also announced that a special task force would be convened to examine the safety practices of ammonia‑based refrigeration facilities across Oregon, with recommendations expected within the next three months.In the coming days, city officials anticipate a gradual return to normalcy as air quality improves and structural assessments of the damaged plant are completed. The Astoria Planning Department will conduct a thorough review of the site’s compliance with fire‑code regulations, while the Oregon Occupational Safety and Health Administration (OSHA) plans.
