起重机械作业人员职业适性检测指标研究 总被引:5,自引:1,他引:4
采用Delphi法对起重机械作业人员职业适性指标进行了研究。咨询专家就各备择指标对工作重要性及发生事故的关系进行了评估。结果表明:专家积极程度与意见集中程度良好;事故重要性与工作重要性排序一致性良好,两者呈高度正相关。依据专家对“重要性”的排序,再通过专家会议与现场考证等方法,最终确定了起重机械作业人员职业适性检测指标体系。 相似文献

Lifting operations and associated equipment have become commonplace within the UK construction industry. However, recent high profile accidents involving lifting equipment have shown that the result of its misuse can have serious cost and health implications.The main aim of the research was to investigate lifting operations on construction sites exploring different options, their effectiveness, and their effect on safety. This research looked into the processes in place; the factors that have to be taken into consideration when placing and using lifting equipment; and the competent persons required when operating equipment. With these aims, literature review was conducted. This was followed by investigation on three construction sites. These case studies were enhanced through interviews with general site staff, managerial staff, and appointed persons.The findings revealed six main points to improve safety in lifting operations. These are: through planning; training; equipment selection, use and inspection; feedback/communication; appointed person’s role; and database. Thorough planning of lifting operations has positive effects on safety. There is need for tighter accreditation of all qualifications in the lifting operations field. The charter of major lifting equipment from specialist contractors should be considered as industry best practise. Companies should avoid authoritarian working culture to facilitate efficient feedback to improve safety. The appointed person should have site based role. Site inspections and maintenance should be monitored on a national database form.Practitioners can benefit from this paper as it provides information on experiences from three construction sites. Furthermore, researchers can use the findings for their future studies. 相似文献
