- This is a completely new basic industry for Sweden where we also need to build up this knowledge together with the rescue service, healthcare and also, for example, the Swedish Work Environment Authority and the unions, says Anders Thor, press officer at Northvolt.

In the video, SVT follows the facility on Finnslätten in Västerås.

There was, for example, an incident on Christmas Day that led to major efforts by the fire brigade, police and medical care.

An event you now learn from in several ways.

- Now we are working on how we can create security in that things happened automatically and that people were not exposed to danger.

We have discussions with both the fire brigade and the health service about how we can make the efforts smaller, says Anders Thor.

The safety and work environment work that is done in Västerås will also be a certain basis for that in the company's giant factory in Skellefteå, according to Anders Thor, press officer at Northvolt.
