A 37-year-old Bulli man was killed in an industrial accident at Coniston on Wednesday afternoon.
Police say the man and a colleague were handling large sheets of glass using an overhead crane at a glass manufacturer in John Cleary Place when the glass fell on him about 3pm.
Work colleagues attempted to assist the man but he had died by the time the ambulance officers arrived at the scene.
The second man was being treated for head injuries at Wollongong Hospital.
WorkCover is investigating how the accident occurred, while police are preparing a report for the coroner.
