Emergency services responded to a dangerous ammonia leak aboard a vessel docked at Skattøra in Tromsø on Wednesday morning. Four crew members required hospitalization after exposure to the toxic gas.
Operations commander Christian Andreassen from Troms police district confirmed the incident. Authorities established a security perimeter and evacuated areas near the leak source in the ship's engine room.
First responders contained the gas leak quickly according to on-site commander Christoffer Skjelbred. He stated the situation appeared serious initially but emergency teams gained control rapidly.
All four affected crew members were transported to University Hospital of North Norway for medical evaluation and treatment. Officials have not yet determined the severity of their injuries.
The vessel carries a total crew of 22 people. Ventilation procedures are currently underway to clear the ship of remaining toxic fumes. Normal operations can continue in the surrounding area with no current exposure risk to others.
Police investigation will determine the cause of the ammonia leak once conditions permit safe examination. Traffic along nearby Stakkevollvegen road remains unaffected.
Ammonia leaks represent serious workplace hazards in maritime industries. The chemical can cause respiratory damage, burns, and potentially fatal exposure at high concentrations. Norway's strict maritime safety regulations typically prevent such incidents, making this event particularly notable.
Northern Norway's fishing and maritime transport industries frequently use ammonia in refrigeration systems. Proper maintenance and safety protocols are essential for preventing dangerous exposures. This incident highlights the ongoing challenges of managing hazardous materials in remote Arctic locations.
Local emergency response capabilities proved effective in this case, containing the situation within hours. The rapid containment prevented potential environmental contamination and broader health impacts. Similar incidents in the past have sometimes required larger evacuations and longer recovery periods.
Maritime safety experts will likely examine whether this indicates broader maintenance issues within Norway's fishing fleet or represents an isolated incident. The investigation findings could influence future safety regulations and inspection protocols.
The affected vessel remains docked at Tromsø Terminal on Skattøra while cleanup and investigation continue. Crew members not hospitalized are presumably assisting with the ventilation process and initial damage assessment.
