Smoke Development at Northvolt in Västerås

The alarm about a fire at Northvolt's facility outside Västerås was no fire.

It's a warm-up in a ventilation fan. That's where the smoke has come from. We're still there and trying to get the smoke out, says Kurt Jonsson, control operator at Rescue Centre Mitt.

The alarm came to SOS Alarm at lunchtime on Friday and the facility was evacuated. No one needed to be taken care of or taken to hospital.
