Björn witnessed the explosion: "I felt the vibrations in the floor 150 meters away"

It was he who alerted SOS Alarm as he ran out and out to the front door where it had just slammed.

- We saw a big explosion, a strong light and sparks that flew, I guess it was ice shattering, and then smoke development. From what I have understood, the bang has been heard over most of Ludvika.

How did you react?

- I felt that I had to quickly go there and check if anyone had been injured. I was not afraid of my own part, but I did not want to stay where I was if there could be injured who needed help, says Björn Wåhlander.
