"The refinery is still online and production has not been impacted," Cindy Govender said in response to questions.
On Friday night an official at the refinery, situated in the eastern port city of Durban, said an explosion had occurred outside the refinery.
Govender confirmed three people were injured and hospitalized and that it was too early to ascertain the extent of the damage to infrastructure or the cause of the fire.
"Investigations are currently underway," she said.
