Rescue services worked for much of the night to prevent the fire from spreading to surrounding properties.
The police have opened a preliminary investigation into public endangerment and endangerment of others. There are no reports of personal injuries, says Johan Ljung, the duty officer.
The fire alarm was reported at 8:30 p.m. on Thursday.
There are chemicals in the premises and there was rapid fire development.
An emergency public alert was issued, but has now been revoked.
