Only the basement remains of the tenement house at 12 Kraszewskiego Street in Poznań. It was here – as the tvn24.pl portal learned – that investigators, experts and firefighters who took part in the tragic fire extinguishing operation, during which two of their colleagues died, appeared. – We will conduct a procedural experiment. For us, these are key activities – says prosecutor Marek Piegat, the prosecutor supervising the proceedings concerning the burned tenement house.
Investigators are currently uncovering more fragments of the tenement house. A partial inspection of the scene is scheduled for Thursday. – We do not have any breakthrough findings yet – says prosecutor Marek Piegat to tvn24.pl.
As tvn24.pl has established, at 9 am a trial experiment was launched with the participation of firefighters taking part in the action. However, not everyone can take part in it. Obviously, two firefighters who died in the fire are missing. Some of the firefighters were absent due to their health, several are performing other duties and were unable to appear on Kraszewskiego Street at that time.

Investigators will reconstruct the firefighters' route, determine where they were moving, who was standing where, and where the explosion caught them.
The firefighters participating in the experiment will be questioned individually by investigators. “We will put all the findings on one grid, which will give us a detailed picture of what the entire operation looked like. For us, these are key activities,” Piegat explains.

They entered the battery warehouse
To determine the cause of the fire and explosion, investigators will need detailed laboratory tests. They managed to enter, among other places, workrooms where batteries were being repaired. “There are a lot of cells there, some of them burnt out,” Piegat reveals.

Now they will try to analyze which cells could have reacted and started the fire or explosion in the tenement house, and which were burned as a result of the fire. “We are collecting them, trying to count them. It is a painstaking task. We will try to determine how many cells there could have been and what their fuel potential was, which could have fueled this event,” Piegat explains.
The data that investigators collect will be needed to model the digital course of the event. This will be done by experts from the Poznań University of Technology. – The time of their work will depend on the number of supercomputers used for this purpose and the amount of data – explains the prosecutor.

As he adds, the amount of data and numbers to enter and formulas exceeds the capabilities of ordinary computers. – We do not know yet whether we will use only the supercomputers that the university has in its resources, or whether we will use supercomputers from the Poznań Supercomputing and Networking Center – says Piegat.

A fire and explosion in a tenement house at 12 Kraszewskiego Street in Poznań occurred on the night of 24-25 August. Emergency services were called to a fire in the basement. Residents began evacuating before the emergency services arrived. Five minutes after the call, firefighters were already on site. While searching the basement for the source of the fire, two explosions occurred, after which the fire quickly spread.
Two firefighters who were conducting reconnaissance in the basement were killed. Eleven firefighters and three civilians were injured. Deputy Minister of Internal Affairs Wiesław Leśniakiewicz said that “the force of the explosion was so great that it ripped off the helmets of the firefighters' heads”. At the peak of the firefighting operation, about 100 firefighters and about 30 vehicles were working on the site.
An investigation into the fire was launched. Demolition of the burned tenement house began in early September.
