Several tons of automobile grinding residue caught fire Monday night at a factory for manufacturing heavy equipment converted to storage space in Frameries, Belgium.
Smoke released from the fire was analyzed and found to be non-toxic. However, RTL reports that waste grinding residue is not allowed to be stored at the facility.
Mutual aid was requested from the nearby Walloon region city of Mons.
Firefighters had been called to the site for a major fire previously in January.
