叉车用安全装置的开发

以机械设备为起因的工伤事故中,叉车事故比较常见。首先介绍了日本国内叉车事故的分类统计数据,从硬件设备方面,概述了叉车减灾的主要措施,针对驾驶员在行驶中将肢体伸出驾驶仓外时易发生冲撞或挤压事故的情况,提出了基于光幕及激光扫描器的驾驶员肢体伸出仓外的监控方法。然后根据叉车的不同刹车性能指标,探讨了如何设定检测领域大小的问题。对蓄电池式1.5t叉车进行的实验表明,在检测系统能直接控制刹车的情况下,我们提出的方法是行之有效的。     

基于CA-SEM的煤矿安全事故风险因素结构模型

围绕煤矿安全风险管理的内涵,通过因子分析和层次聚类分析,识别煤矿安全事故风险主要包含人因风险、管理风险、信息风险、环境风险和设备风险5个风险因素层的22项风险因子。以人因风险层的6个风险因素为内源潜变量,其他4个风险层的16个风险因素为外源潜变量,构建煤矿安全事故风险因素的CA-SEM模型。运用SPASS17.0和AMOS7.0剖析各风险因素层以及各风险因子对煤矿安全事故风险的综合影响及其作用机理,从而为实现煤矿本质化安全提供决策依据。     

营运驾驶员驾驶事故影响因素仿真研究

解决营运驾驶员驾驶事故频发的不安全行为问题,基于复杂适应系统（CAS）理论和多主体建模与仿真（ABMS）方法,构建营运驾驶员驾驶事故模型。通过调节车辆状况、管理者管理监督水平、营运驾驶员情绪状态、安全教育水平、驾驶经验和环境综合条件等因素,运用NetLogo仿真平台分析安全管理水平、营运驾驶员安全责任意识、心理负荷水平对驾驶事故的影响。研究表明:营运驾驶员驾驶事故的发生系统是一种典型的CAS,营运驾驶员驾驶事故是三大主体属性和行为环境交互的结果,且交互作用程度不同。因此,运输企业要考虑多种因素,采取相应的措施来降低营运驾驶员驾驶事故的发生。     

基于加权线性回归模型组的湖北省工矿事故死亡人数分析预测

以2005-2014年湖北省工矿企业事故死亡人数为基础,通过对时间序列图分析可知,该省工矿企业事故具有明显的周期性、季节性。另外,依据安全系统特征属性,系统近期的状况相对远期的状况对未来预测更具有影响力。因此,各个季节数据的权重应有所不同。综合考虑以上两种情况,提出对4个季节建立不同的线性加权线性回归模型,并进行组合,形成加权线性回归模型组,进而对2015-2016年各个季度进行预测。最后,与传统的时间序列分析方法比较可知,加权线性回归模型组的方法建立的模型显著性、拟合度更高,并且模型的可读性更强、更简单。     

Risk taking and accident frequency among Finnish forestry workers

The results of previous studies on the relationship between risk taking and accidents have been contradictory. The aim of this study is to examine the relationship between risk taking and accident frequency among Finnish forestry workers. The subjects were 228 forestry workers whose risk taking was measured on a questionnaire with 25 items. The accident frequency was calculated based on both company-recorded and self-reported accidents. There were no significant relationships between risk taking and accident frequency. Even after elimination of age and work experience by partial correlations, there was no significant correlation between risk taking and accident frequency. Of the personality traits of the forestry workers, impulsiveness and neuroticism correlated significantly with risk taking but not with accident frequency. Two explanations for the failure to find significant correlation between risk taking and accident frequency are given.

The significance of domino effect in chemical accidents

A historical survey was performed on 330 accidents involving domino effect, occurred in process/storage plants and in the transportation of hazardous materials; only accidents occurred after 1st-January-1961 have been considered. The main features – geographical location, type of accident, materials involved, origin and causes, consequences, domino sequences – were analyzed, with special consideration to the situation in the developing countries and compared to those from other previous surveys. Among the involved substances, LPG was the most frequent one, followed by liquid hydrocarbons. Process plants (38.5% of cases) and storage areas (33%) were the most common settings; 10.6% of past domino accidents occurred in transfer operations. The ratio between “two-step” and “three-step” domino accidents was found to be 6. A specific analysis of the accidents (84) occurred in the 21st century was performed, comparing them with the total set of accidents. Finally, a set of specific recommendations inferred from the results is provided.
