Work in confined spaces is 150 times more dangerous than the same jobs carried out elsewhere. An example is work-at-height, where what is important is how far you can fall regardless of where it is, as an unfortunate seafarer discovered to his cost on the 498 tonne trawler Darwin on 19 August 2009.
A report on the incident released by the Danish Maritime Authority concludes that the seafarer lost his grip on the ladder while climbing out of a RSW-tank, was fatally injured in the fall and did not recover consciousness.
