Prioritizing prevention opportunities in the Washington State construction industry, 2003-2007

Objective

This study compares construction industry groups in Washington State by injury severity and cost, and ranks industry groups according to potential for prevention.

Methods

All Washington State workers' compensation compensable claims with date of injury between 2003 and 2007 were classified into North American Industrial Classification System (NAICS) industry groups. Claims were then aggregated by injury type and industry groups were ranked according to a prevention index (PI). The PI is the average of the rank orders of the claim count and the claim incidence rate. A lower PI indicates a higher need for prevention activities. The severity rate was calculated as the number of days of time loss per 10,000 full-time equivalents (FTEs).

Results

For all injury types, construction industry groups occupy 7 of the top 15 PI ranks in Washington State. The severity rate among construction industry groups was twice that for non-construction groups for all injury types. Foundation, structure, and building exterior contractors (NAICS 2381) ranked highest in prevention potential and severity among construction industry groups for most common injury types including falls from elevation, fall on same level, struck by/against, and musculo-skeletal disorders of the neck, back, and upper extremity (WMSDs). Median claim costs by injury type were generally higher among construction industry groups.

Conclusions

The construction industry in Washington State has a high severity rate and potential for prevention. The methods used for characterizing these industry groups can be adapted for comparison within and between other industries and states.

Impact on Industry

These data can be used by industry groups and employers to identify higher cost and higher severity injury types. Knowledge about the relative frequencies and costs associated with different injury types will help employers and construction industry associations make better informed decisions about where prevention efforts are most needed and may have the greatest impact. The results of this study can also be used by industry stakeholders to cooperatively focus on high cost and high severity injuries and explore best practices, interventions, and solutions as demonstrated by efforts to prevent musculoskeletal disorders in masonry (Entzel, Albers, & Welch, 2007). Initiating construction industry groups to focus on high cost and high severity injuries may also help prevent other types of injuries.     

小煤矿透水事故分析及预防

通过对乡镇小煤矿透水事故典型案例分析,得出其事故发生原因主要在于从业人员素质较差、内部管理混乱、技术装备力量薄弱和行业主管部门监督不力。因此,煤矿防治水害要坚持以防为主。同时,提出不仅要从辨识透水征兆、留设防水煤柱、规范探放水安全距离、组建探放水机构等技术方面上,还要加强从业人员培训、编制防灾救援预案、行业主管部门监督等方面采取措施。另外,还提出"防、堵、疏、排、截"5项综合治理措施。     

煤矿安全风险预控与隐患闭环管理信息系统设计研究

从事故风险管理理论出发,借鉴国外风险管理的流程和方法,总结国内煤矿安全管理中隐患治理的先进实践经验,设计了满足煤矿危险源辨识、评价、管理标准与措施制定流程的风险预控管理,隐患治理中的反馈式闭环管理以及员工"三违"的流程管理需求的煤矿安全管理信息系统。通过安全管理信息系统的实施,能够使煤矿的风险管理系统化、规范化,煤矿生产中的潜在危险源得到有效管理,隐患及人员不安全行为能够得到及时控制,避免或减少煤矿事故的发生。     

基于层次分析法的烟火药制造过程爆炸事故分析

结合烟花爆竹行业安全评价经验,在危险源辨识理论的指导下,运用因果图法对该过程发生的爆炸事故进行定性分析,找出导致事故发生的因素;再运用层次分析法(AHP)进行定量分析,建立层次结构模型,求出各因素的权重,得出各因素的重要程度,从而确定导致事故发生的关键因素,以此作为事故预防的重点。结果表明,人的不安全行为是影响事故的主导因素,此结论符合烟花爆竹行业生产现状,可以为企业制定合理的、有针对性的对策措施提供依据。     

化工生产事故预防信息系统研究

为指导操作人员正确地处理化工生产过程中的问题,防范人为误操作导致的事故发生,开发了以化工生产的危险与可操作性分析结果和典型事故原因分析结果为知识库的事故预防信息系统.系统实时在线监测化工生产过程中的关键变量,通过判定变量间的影响关系,实现对化工生产过程潜在危险的辨识、预警并给予实时操作指导,以确保生产安全,提高装置的生产效率.最后,以丙烯聚合工艺为例,在多功能过程试验控制平台上进行了验证,探讨了事故预防信息系统的应用方法.     

分布式防震减灾系统的初步设计
