A man has died after being trapped inside an "extremely hot" ink Value-Added Tax at a factory in Sydney's west.
"The third patient is now deceased".
"I believe there's a mixing blade in the Value-Added Tax and that's what they've become trapped on".
Emergency services rushed to Chisholm Road in Auburn just before 8.45am after receiving reports three workers were trapped inside a tank.
Paramedics, NSW Fire & Rescue and Police Rescue are on the scene.
"My understanding is that they were cleaning a Value-Added Tax used for ink; they were in there doing maintenance cleaning and they've become trapped in the Value-Added Tax ..."
New South Ambulance superintendent Paul Turner said the worker had been trapped by his legs, describing the area as "a very hard scene".
The conditions in the tank were "hot", he said.
Both men were taken to Westmead Hospital with multiple leg fractures and are in a stable condition.
A NSW Ambulance spokesman earlier said the extraction operation was expected to take several hours.
Ambulance parademics at the scene told reporters the injuries were likely to have been caused by falling into the Value-Added Tax instead of the chemicals inside.
"We did absolutely everything we could".
'It was a complex operation.
The man's body was removed from the ink tank on Thursday afternoon and his next of kin has been notified, a NSW Police spokeswoman told AAP.
SafeWork NSW has also sent inspectors to the site to investigate, a spokesman told AAP.
