Diemould Tooling Services, an Adelaide engineering firm, has been convicted and fined $72,000 over safety failings which led to the death of an 18 year old first year apprentice.

Daniel Madeley was fatally injured on June 5, 2004, when his dustcoat became caught on the unguarded spinning shaft of a horizontal borer at the company's Edwardstown premises, dragging him into the machine.

Safework South Australia's investigation uncovered a number of safety failures including the fact that the machine was completely unguarded, there were no interlock devices to prevent contact with dangerous moving parts, training and supervision were inadequate, the dangers of the borer weren't identified and loose fitting dustcoats should have been banned under a safe operating procedure.
