The shift in the international balance of power at the beginning of this decade dramatically changed the parameters of risk within which the DOE operates. Just a few years earlier federal and state regulatory authority were extended to the waste and environmental aspects of the nuclear weapons complex operations. For many, this also introduced an abrupt change to the historic perception of the risks of these operations. DOE, in the Energy and Research sectors, faces changes in risk management practices as these activities, still governed by DOE’s self-regulation authority in occupational and nuclear safety, are more and more compared to private sector counterparts for cost and safety performance. DOE intends to establish a contemporary, standards-based, integrated safety management system. However, the development of guidance for simultaneous accomplishment of both global and local changes in past practices is far from risk-free. The work of Department Standards Committee provides insight to change management challenges and opportunities on a department-wide scale. The Work Smart Standards protocol developed by the Committee promotes a focus on understanding the actual work/hazards matrix as seen from the perspective of multi-disciplinary teams with concise and relevant experience of that specific work. It also draws attention to the essential role that agreements play in achieving closure on planning and the implementation of plans in the face of persistent uncertainty from a wide variety of sources.","PeriodicalId":334155,"journal":{"name":"Safety Engineering and Risk Analysis","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121722129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Committee wanted proof that reliable Work Smart Standards sets could be selected consistently across the range of DOE sites, facilities, and work activities. The Committee got the evidence it needed. Whenever and wherever a Pilot demonstration followed the process rigorously, a reliable Work Smart Standards set was selected, confirmed, and approved. Indeed, the results from these “Pilot demonstrations” were so promising that fifteen “Second Round” Work Smart Standards applications are underway, with more in the wings.

Outcomes of motor vehicle accidents result from interactions among several or more pre-crash and at-crash factors. The inherent complexity of motor vehicle accidents often defeats traditional approaches to multivariate regression analysis. This paper introduces a new technique called crash scenario analysis. Rather than treating many causal factors as discrete variables, combinations of factors define crash scenarios. A single variable (scenario risk) measures the likelihood of crash outcomes for vehicles involved in each unique scenario. The authors applied crash scenario analysis to vehicle rollover and used logistic regression to estimate the importance of vehicular factors relative to scenario risk. Findings indicated that scenario risk was a much stronger predictor of rollover in fatal crashes than vehicle static stability factor (T/2H).","PeriodicalId":334155,"journal":{"name":"Safety Engineering and Risk Analysis","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130748634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three approaches were taken to investigate the potential risk associated with such devices. A review of studies involving other in-vehicle devices revealed that drivers can safely time-share visual attention between the road and a display. An experiment conducted in a controlled driving environment found that head and eye movements while using an on-board truck computer were similar to those for common devices and activities such as operating a radio or checking the odometer. Analysis of accident reports from North Carolina and the Fatal Accident Reporting System showed that in-vehicle devices were only rarely cited as distracters in accidents. Based on these findings and on the safety benefits provided by truck computers, it is expected that these will have a net positive impact on truck fleet safety.","PeriodicalId":334155,"journal":{"name":"Safety Engineering and Risk Analysis","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114712762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
