环境污染事故调查诊断中的因果关系分析

因果关系分析与确定是整个环境污染事故调查诊断的核心，探讨了环境污染事故处理中因果关系的特点，因果关系分析基本原则和内容，因果关系分析的基本步骤，并简介环境污染事故中因果关系推定原则和环境暴露分析方法。     

基于主逻辑图的安全风险建模研究

概率风险评估已成为研究复杂系统安全风险较为成熟的方法 ,其风险模型的建立是基于故障树/事件树的 ,风险分析具有众多的静态特性。然而 ,大的复杂系统往往存在诸多动态因素 ,在风险研究需要考虑这些动态因素的情况下 ,基于传统故障树 /事件树的模型则难以提供支持。笔者对此进行了分析 ,提出了基于主逻辑图的安全风险建模 ;主要介绍了主逻辑图的概念及其建模方法 ,并对模型进行了分析 ;在此基础上 ,基于主逻辑图分析事故场景 ,对场景风险的量化评估进行了简要介绍 ,并结合某核反应堆例子进行了分析。

中国煤矿工人体能负荷、疲劳与工伤事故

煤矿井下事故对矿工威胁很大，体力负荷过重而导致疲劳是引起事故不可忽视的原因。测定不同工种井下矿工的体能负荷情况，并根据ＦＩＸ疲劳指数的测定，分析矿工劳动负荷与工伤事故发生之间的关系。研究表明，在疲劳状态下事故发生的危险性增加；劳动负荷越重，疲劳越重相对的事故发生率也越高。减轻疲劳对预防事故发生与保证工作安全具有很重要的意义     

Incidents in manual handling activities

More than 20000 handling manoeuvres in loading or unloading trailers in a large transportation company were observed. The aim of the study was to determine the frequency and nature of the incidents occurring whilst handling. The incidents were recorded and interpreted from a double perspective, namely as risk factors and as activity regulation factors. The study showed that on average, one incident occurred in every seven handling manoeuvres: 71% of them were related to the environment, and 29% to the activity. While numerous, the environment-related incidents were generally without consequences. In this respect, the activity incidents appeared more risky; also, the majority of these incidents occurred during the load positioning phase. The study also showed that loads are re-handled twice as often in unloading as in loading, the frequency of re-handlings varying widely from one handler to another. The reasons why so few of the observed incidents are reported in accident studies and their significance in the understanding of handling problems are discussed.     

Accidents and risk control

A framework for transformation of knowledge and experience from risk analysis to emergency education is presented. An accident model was developed built on the concept “uncontrolled flow of energy (UFOE)”, where essential elements are the state, location and movement of the energy. A UFOE can be considered as the driving force of an accident, e.g. an explosion, a release of heavy gases. A domain model has been developed for representing emergencies occurring in society. A domain is a group of activities with allied goals and elements, and the domain model uses three main categories: status, context and objectives. Ten specific domains have been investigated including process plant, energy production and distribution, natural disasters and different sorts of transport. Totally 25 accident cases were consulted and information was extracted for filling into the schematic representations with two to four cases pr. specific domain.     

煤矿人为事故发生可能性预测数学模型研究

研究发现，煤矿工人的冒险行为主要可以由生产条件、个人表现、工作状况及用工方式等影响因素预测，煤矿人为事故的发生可能性主要由煤矿工人的冒险行为表现预测。据此，便可建立预测煤矿人为事故发生可能性的数学模型     

关于安全投资效益目标函数的建立和优化

通过对安全投资与事故经济损失的规律性的分析研究，确立安全投资与经济效益的内在关系，进一步探索在我国现有财力和安全水平的基础上，找准安全投资的投向，优化安全投资的合理分配，从而实现最大限度地提高企业安全生产水平和安全投资效益。为政府部门或企业提供一套经过优化、科学合理、操作性又比较强的安全投资方案，供各级领导进行安全决策，实现本部门、本单位的安全投资计划时参考     

推广工伤保险对我国生产事故统计的影响

我国安全生产统计工作所依托的行政手段还不能完全适应变化中的市场经济环境 ,政府安全生产管理不到位 ,监管不严 ,各类事故的少报、瞒报、不报现象相当普遍 ,极大地影响了伤亡事故统计的准确性。2 0 0 4年我国已实施新的《工伤保险条例》 ,笔者认为 ,会在一个较长的时期内对生产事故统计带来较明显的影响 ,使生产事故造成的伤亡人数统计变得更为全面和科学 ,这种影响必然会对原有统计偏差的修正 ,有利于今后加强和完善对安全生产的宏观决策和管理 ,会从根本上促进安全生产水平的提高。     

The indirect involvement of buses in traffic accident processes

The involvement of buses in accidents usually is assessed implicitly on the basis of the direct involvement of the bus in the collision or in injury production. This paper deals with the scope and forms of indirect involvement of buses (as a sight obstruction, for example). Accidents were selected by identifying the presence of the term ‘bus’ or synonyms in the text parts of complete police reports (testimonies, statements by the persons involved, etc.) available in electronic form, then analysed in detail. Direct or indirect involvement of a bus is found in 3.6% of traffic injury accidents reported by the police in the community studied (direct involvement: 1.4%; indirect involvement: 2.2%). The different forms of indirect involvement are then described, and some possibilities of preventive measures are discussed.
