Major Factory Fire in Oborniki Sparks Chemical Leak Warning
A major industrial fire erupted Wednesday afternoon, May 27, at the FAM S.A. Production facility in Oborniki. The blaze targeted a production hall on Kowanowska Street, which housed two modern galvanic zinc production lines.
The scale of the incident was immediately apparent, with a column of thick black smoke visible from several kilometers away. Emergency services responded with massive force to contain the flames and prevent them from spreading to neighboring industrial buildings.
Emergency Response and Public Safety
At the peak of the operation, approximately 60 fire units and 250 firefighters were deployed to the scene. The fire was eventually brought under control around 5:30 p.m., though portions of the hall were destroyed.
Due to the density of the smoke, the Government Security Centre (RCB) issued alerts to residents of Poznań and the Oborniki and Poznań districts. Authorities advised citizens to stay indoors, close all windows and doors, and avoid the immediate area of the operation.
Chemical Hazards and Environmental Risks
The firefighting effort was significantly complicated by the presence of acid tanks used in the production process. Officials confirmed that these tanks suffered leaks, resulting in acids becoming diluted with firefighting water.

This chemical breach prompted a secondary RCB alert warning of the potential contamination of the Warta river. Residents were urged to limit all activity in the vicinity of the river to avoid possible exposure.
Specialized chemical groups from Poznań and Piła were deployed to monitor the concentration of substances flowing with the firefighting water. Representatives from the Provincial Inspectorate for Environmental Protection (WIOŚ) and Polish Waters (Wody Polskie) joined the effort to assess the impact on the soil and water.
Potential Aftermath
While the fire is controlled and no injuries have been reported, the environmental impact remains a primary concern. It is likely that ongoing monitoring of the Warta river and local soil will be necessary to determine the extent of the chemical seepage.

A possible next step involves a detailed investigation into the cause of the fire and an assessment of the structural damage to the galvanic zinc lines. Authorities may continue to monitor air and water quality until the chemical concentrations return to safe levels.
Frequently Asked Questions
Were there any casualties in the fire?
There is currently no information regarding any injured persons.
What caused the environmental alert for the Warta river?
The alert was issued because acid tanks at the facility leaked, and these substances may have flowed into the river along with the water used by firefighters.
Who was involved in the emergency response?
The response included up to 60 fire units, chemical groups from Poznań and Piła, the Provincial Inspectorate for Environmental Protection (WIOŚ), and Polish Waters.
How should industrial zones be better equipped to prevent chemical runoff during emergency firefighting efforts?
