  1. 1. Prison sentences for fatal crane accident 17 November, 2009 A court in Taiwan has given prison sentences to six people held responsible for a fatal crane accident in April of this year. The Taipei District Court handed down prison sentences ranging from eight to 10 months for those involved in the accident that killed three Chinese tourists when the tower crane‘s jib hit their bus. On the afternoon of April 24, the jib fell from the 37th LIFTING MATTERS floor of a high rise construction in Taipei's Xinyi District, landing on the back of a tour bus carrying 25 tourists from Guangdong Province of China. Prosecutors said that the luffing jib tower crane had a Published in the interest of promoting safety in the crane industry maximum capacity at its boom length and radius of 3.2 tonnes and yet was lifting a total of five tonnes. In addition, the crane was being operated in high winds and the construction company had not cordoned-off the area below the lift. The district court found the rigging company and the sub -contractor‘s engineer and five other employees, includ- Sharing and Learning ing the team leader, a crane operator and three other men from the crane operations team, guilty of causing death by occupational negligence. The judgment said the six showed remorse for their crimes and were unlikely to repeat such negli- gence and so received two years probation. The sentences can also be appealed. http://www.vertikal.net/en/news/story/9089/ THE EXECUTIONER, THE AXE AND THE SAFETY OFFICER Once upon a time there lived three men: a doctor, a chemist, and an Safety Officer. For some rea- son all three offended the king and were sentenced to die on the same day. The day of the execution arrived, and the doctor was led up to the guillotine. As he strapped the doctor to the guillotine, the executioner asked, "Head up or head down?" "Head up," said the doctor. "Blindfold or no blindfold?" "No blindfold." So the executioner raised the axe, and z-z-z-z-ing! Down came the blade--and stopped barely an inch above the doctor's neck. Well, the law stated that if an execution didn't succeed the first time the prisoner had to be released, so the doctor was set free. Then the chemist was led up to the guillotine. "Head up or head down?" said the executioner. "Head up," said the chemist. "Blindfold or no blindfold?" "No blindfold." So the executioner raised his axe, and z-z-z-z-ing! Down came the blade--and stopped an inch above the chemist's neck. Well, the law stated that if the execution didn't succeed the first time the prisoner had to be released, so the chemist was set free. Finally the Safety Officer was led up to the guillotine. "Head up or head down?" asked the execu- tioner. "Head up." "Blindfold or no blindfold?" "No blindfold." So the executioner raised his axe, but before he could cut the rope, the Safety Officer yelled out, "WAIT! I see what the problem is!"

  2. 2. EDITORIAL OFTEN the most visible pieces of equipment on a construction site or in a factory, cranes also have the potential to be the most dangerous, with accidents resulting in extensive damage to equipment and workers. Since the Australian Standards 2550 series was introduced, the onus is on the equipment owner to demonstrate that their inspection regime and maintenance procedure is equal to or better than the Australian Standards. Under the standard, cranes are required to be checked periodically every three months, with major certification and refurbishment compulsory at 10 years for mechanical and 25 years for structural inspection to assess their suitability for continued safe operation. So companies and crane operators, who for their own reasons short cut on accepted good mainte- nance practice, should seriously consider their position within the crane industry for their own safety and that of their own and other workers. The Australian State, Territory and Commonwealth Governments have agreed that by the end of 2011, new harmonised Occupational Health and Safety model legislation will replace all existing State and Territory OHS laws. What harmonisation promises is that these standards will be expressed and enforced consistently throughout the country. Each state will have it‘s own regulator. Importantly, these regulators have agreed to work to a national enforcement and compliance protocol, so that they interpret and en- force the new law in the same way. Australia‘s workplace safety standards and outcomes are among the best in the world, and legisla- tion that is consistent across all jurisdictions will ensure we stay that way. The HSE alert (page 3) is from 2004 but a reminder to check on our procedures around luffing ropes would be timely. A very funny story (page 04) ‗Bricklayer‘s Report‘, should bring a smile to your faces and a revisit to the 160T Demag tip-over in Perth last month (page 05) sheds more light on what actually happened. The ‗Fatality During Load Testing‘ report (page 06) again underlines the highly dangerous practice of using mobile phones during crane operations. An alert from the HSE in the UK on the safe erec- tion, operation, maintenance and dismantling of tower cranes appears (page 08). Working at heights it seems will always be an issue on worksites around the world as can be seen in the articles on pages 07, 09, 10 and 11.
