transfer of the liquid steel into the caster, causing a spill. The area was controlled and secure as of approximately 2:25 PM. Fortunately there are no injuries as employees are not allowed in the area for safety reasons. However, the incident resulted in a significant visible emission, likely due to both fire and contact between the liquid steel and water. The company’s Fire Department responded and managed the incident, while Hamilton Fire was also on site to support. Most of the douse water, approximately 30,000 litres, evaporated and the remainder went into the facilities treatment plant and containment pond. No foam or chemicals were used in fighting the fire
However, the incident caused a grey plume to rise into the air. The emission contained dust from the steel, steam generated by the reaction between the water used by firefighters, and the liquid steel and smoke from the combustibles in the area that caught fire. ArcelorMittal Dofasco's spokesperson Ms Marie Verdun said "Combustibles would be things like equipment, cabling, and fluids in the equipment, for example.”
A report has been made to the Ontario Ministry of Environment, Parks and Conservation’s Spills Action Centre, which later said that workers allowed the molten spill to solidity and then cleaned it up.
