ArcelorMittal Dofasco experienced what is referred to as a “bleeder pop” at one of our blast furnaces (this is where we utilize coke made from coal and lime stone to make liquid iron. Liquid iron is then used to create liquid steel).

The incident happened at approximately 12:30 a.m. this morning and lasted for 15 seconds. The incident was reported immediately to the Ministry of Environment and Climate Change and our environment team has conducted an investigation into the incident and its full impact. The release caused particulate (combination of iron, ore fines, coke fines, carbon and coal) to fall onto industrial property but did not extend into the community, away from our property.

Bleeder pops are common to all blast furnaces and happen when a safety valve is released because pressure in the furnace is too high.
