Nyrstar has yet to agree to discuss over the incidents which occurred at the smelter early this January. The first incident involved a 53-year-old male worker who sustained burns to both his face and neck while cleaning a hot flue.
Sometime afterwards, a 43-year-old worker suffered burns on his feet, thighs and hands while cleaning waste products in the same area.
Both men were treated at Royal Adelaide Hospital.
SafeWork SA has rejected any request to reveal further details until a thorough investigation has been conducted to determine if there have been any breaches of work health and safety laws
