The emergency services have been at the scene for nearly two hours, trying to stop the blaze.
It is not clear what caused the fire, however, the conveyor belts that were being stored in the area caught fire and produced heavy fumes that drew the attention of a security guard.
The security guard quickly alerted emergency services, including the military police.
CPF members are currently restricting access to the area due to explosives present in Reclam, which used to be a recycling facility for ferrous and non-ferrous metal products.
The business has been non-operational for several months.
As of yet, no reports of injuries have been made.
