Crews deployed 20 fire trucks to the scene, and upon arrival, firefighters discovered intense fire activity, with flames reaching 60 metres in height.

An 800 metre exclusion zone has been established and evacuations are underway, as ongoing explosions and stores of chemicals are making it an extremely dangerous and complex operation.
