The importance of adequate training, reviewing and maintaining control measures, even something as simple as PPE, has been sadly highlighted once more.
A 27-year-old German woman who fell 13 floors to her death on a Perth construction site on Monday had taken her safety harness off only moments before.
Gerry Hanssen, managing director of contractor Hanssen, said Marianka Heumann was ready to end her shift putting silicone in a lift shaft and had taken her safety harness off.
'She must have been ready to knock off but doubled back to fix a mistake,' he told ABC radio.
'She took the harness off and must have looked back and she left a small section 20cm out or something and she obviously thought 'I better fix that before I go'.'
The fall from the high rise apartment complex would have been about 60 metres and the woman was pronounced dead at Royal Perth Hospital.
