WorkSafe's Chief Inspector Steve Kelly said this tragic incident highlighted the need to ensure machinery was guarded.
"The worker shouldn't have been able to access the machine so easily," he said.
"Our message to all businesses is simple – if your worker has to interact with machinery then it must be guarded. The more human interaction needed around machinery, the more vital it is there is adequate guarding in place.
"This particular machine stretched across multiple buildings at the sawmill. Its sheer size
meant workers had to interact with it at different locations and it could only be restarted from one point.
"Had appropriate guarding been in place, this woman might still be alive today," he said.
