The woman, aged 37, was working around 1.30am when the incident happened. She was airlifted to hospital in Melbourne with serious crush injuries to both arms.
WorkSafe is investigating the circumstances surrounding the incident.
WorkSafe Regional Director Shane Gillard said the incident was a horrible reminder of the terrible damage that could be inflicted by dangerous machines.
“Our thoughts go out to this young woman and her family, friends and workmates,” he said.
He said dangerous machines had injured almost 11,000 workers in Victoria in the past five years.
“We know machines are essential to many businesses, but they can be dangerous and must be controlled.”
“Too many workers are still being injured by common types of machines.”
Mr Gillard said while the cause of today’s incident had yet to be determined, it served as a reminder to employers to “get on the front foot” by taking a preventative approach to identifying and controlling the risk of dangerous machines at their workplace.
“Workers should also speak up if they were concerned about safety,” he said.
“If we’re going to keep Victoria the safest place to work, employers and employees have to play their part.”
