The Ministry of Labour is investigating two industrial accidents at ArcelorMittal Dofasco.
Police say a 23-year-old Hamilton man suffered serious but non-life-threatening injuries Tuesday afternoon when the dump-style machine he was driving crashed and tipped over.
The crash caused a diesel spill that Dofasco soon contained.
The second accident took place at around 2:30 am Wednesday morning.
A 26-year-old Hamilton woman suffered minor injuries when the truck she was operating tipped over.
