Forty firefighting units, consisting of some 100 firefighters, were deployed for the operation, which is ongoing.

There were no employees in the hall when the blaze, ultimately covering an area of about 400 square meters, broke out.

The roof of the hall partially collapsed, but firefighters managed to save another part of the facility and an adjacent building.

“The firefighting operation at the warehouse hall in the port lasted all night - the fire was located at around 2:00 a.m., and the firefighting is currently underway,” the state fire service said Monday morning on the X platform.

“This is the largest fire in Gdańsk in recent years,” said one officer.

The deputy chief of Poland’s national fire service said that the operation was “very difficult due to the very large amount of combustible materials, like plastic.”
