At approximately 11:10 AM on December 25 a slag pit eruption occurred at the No 4 Blast Furnace at ArcelorMittal Dofesco’s Hamilton plant. The incident was a series of eruptions that occurred during the Slag Casting process, when slag and molten iron from the Blast Furnace are separated and the slag is cast. In this case liquid slag & iron came into contact with moisture which caused the eruptions. The reaction was between water and primarily liquid iron and would have been comprised of mostly iron, iron oxide and water vapour, as well as silica, calcium, magnesium, carbon dioxide, and carbon monoxide. Thankfully there are no injuries. However the event caused a significant air emission. Ministry of Environment, Conservation and Parks have been alerted. Both ArcelorMittal and Hamilton Fire attended. Hamilton Fire has now left. The site is secure.
Sheri Ovis, a resident living nearby, told CBC Toronto that she heard bangs and it felt like three loud shockwaves. We went outside and saw the huge cloud of brown rusty coloured smoke. Other residents from Hamilton, Stoney Creek and Burlington reported hearing the blast, and some said it sounded like bombs going off.
