Work at height remains work at height when it is carried out in a confined space, as a report into a fatality aboard the Vanuatu-registered bulk carrier Polska Walczaca from the Australian Transport Safety Board. The fatality occured while the victim was intalling a repaired safety handrail on a platform 5 metres above the tank bottom of a cargo hold.
The victim did have a safety harness but was not wearing it, it was found on the platform from which he fell. He also appears not to have worn his hard hat properly, it was found without signs of impact damage some distance from the victim.
The two most obvious lessons are: wear a safety harness, wear a hardhat properly. However, there are other issues worth looking at.
