Celanese had several process safety incidents and near misses in 1996. Although there were several root causes, this article will address only one of them; human error. The system which was developed by Celanese to improve this human element is the conduct of operations system. The conduct of operations system has improved process safety performance of the human element by focusing on three operational areas: training, procedures, and general operations. Conduct of operations is a proactive approach to improve the current practices, improve the support systems and the behavior of the operator. The benefits include the following:
- Consistent application of training and procedures
- Reduction in human error, and
- Less process safety incidents

This article describes a company's experience with process safety metrics and describes systematic methods to improve safety performance. As a result of a major accident, an internal investigation identified that although a site may have numerous measures for tracking operational and safety performance, these measures may not focus on leading indicators that could provide early warning of potential major incidents. To systematically reduce incidents, especially, low probability high consequence process safety events, it is necessary to focus on prevention and specifically the strength of the barriers. The approach described in this article, therefore, aims to create a combination of Process Safety Performance Indicators that lead to stronger more robust barriers. While industrial history tells us that such high consequence events are infrequent, this significant process safety risk is always present in production operations, and thus needs to be continuously assessed and reduced through systematic safety management. Within one company, this recognition has resulted in a substantial strengthening of process safety risk management through a more comprehensive system of controls embedded within its new Operating Management System, which is being implemented at the site level across all of its operations globally. This article explores the ongoing methodology and approach being used to select a limited but crucial set of Process Safety Performance Indicators to enable effective measurement and the appropriate management of process safety performance. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009 相似文献

Consequences of acrylic resin reactor runaways can be devastating, as it is evident in investigation reports of industrial accidents. Critical in preventing major accidents is the safety screening of any acrylic resin formula to be manufactured in large scale. Computer model simulations facilitate the evaluation of “layers of protection” against acrylic polymerization runaways. This work describes the adaptation of a chemical process dynamic simulator (DuPont™ TMODS™) for use in simulating acrylic polymerization runaways. “Loss of cooling” and “monomer pooling (accumulation)” scenarios are the causes of these runaways. Simulations show that scenarios leading to “monomer pooling” result in more energetic runaways and to larger emergency relief capacity requirements than “loss of cooling” scenarios. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009 相似文献

Quantitative Risk Analysis (QRA) has become an often used method in the process industry for improving safety and for land-use planning. In computing the risk by this methodology the frequency of an accident is often assessed by using generic failure frequencies which are based on historical data of incidents from databases. Little or no adjustment is made for the effectiveness of the safety management of the industrial site. Since most incidents are caused by management problems, QRA has to take into account the local safety management system. Otherwise, the results of QRA will not provide reliable information of the hazards and the corresponding risk from installations. Therefore, today's understanding of safe industrial operations requires an integrated risk assessment under the consideration of technical, organizational, and managerial aspects. This article describes a method which allows assessing the effectiveness of the local safety management system and its integration into the QRA using a single management factor. This method was developed with the aim of providing a tool which would allocate a quantitative measure for the effectiveness of the local Safety Management System for the purpose of using it directly in the QRA. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009 相似文献

This paper discusses the globalization process of business-to-business born globals in a rapidly growing industry, the wireless technology industry. Deviations in these patterns in regards to the mainstream pattern of internationalization and earlier born global literature are discussed. Furthermore, the roles of the founders and managers, the networks, the financial resources of the companies, and the innovations behind the companies under consideration are analyzed. A conceptual framework and propositions explaining the product, operation and market strategies of born globals are developed. The results suggest that born globals in the wireless sector do in fact deviate from the traditional internationalization process in many areas. Their expansion even to distant markets is rapid and they apply advanced product strategies at an early stage. However, their business operations are found to proceed at a more conventional pace and the notable difference from traditional firms is the rapid establishment of sales and marketing subsidiaries. Results emphasize the key role of the resources and capabilities of born globals in influencing the advancement of product categories, operation strategies, and global market presence. Born global firms were found to lack the resources and capabilities accumulated by traditionally internationalizing firms, and they therefore need to acquire them either through the earlier experience of the founding team, which should be complementary in nature, or from external domestic and international network actors. 相似文献

为了探讨油库区火灾应急过程中风险因素与事故情景间的量化作用关系,揭示事故发展演化的基本规律,通过对近50年来国内外240例油库区典型火灾爆炸事故的统计分析,从人-物-环境-管理4个方面,建立了二者间的结构方程模型。结果表明:各因素与情景间影响关系显著,其中人的因素影响系数最大,为0.46,且对火灾扩大的情景影响更大,而“误判断”这一具体因素事件最易发生。所构建的结构方程模型能较清晰地量化应急过程风险因素与情景间的作用关系,可为揭示事故发生发展的作用机理提供一定的科学依据,同时为油库区火灾事故应急安全管理提供参考。 相似文献

It is undeniable that safe operation and process reliability are not only compatible but highly interrelated. Reliable production units rarely have safety incidents, whereas unreliable ones tend to repeatedly experience abnormal operation. To prevent incidents, personnel, procedures, and equipment must be aligned to facilitate rapid identification and response to failures of the control system and protective safeguards. Safe and reliable performance requires minimization of the root causes that lead to abnormal and emergency operation. The challenges to accomplishing this in a timely manner are considerable, but not insurmountable. This article discusses various challenges to sustaining safe operation of process equipment. Each challenge is introduced using a philosophical saying from a Chinese fortune cookie to remind the reader that the barriers against progress are not new but have existed from many years. In most cases, the solutions are also well known and generally require deployment of robust equipment, proven techniques, and competent resources. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009 相似文献

Given industry competitiveness, how do firms' new product development (NPD) process designs differ when responding to an innovation mandate? How do NPD design elements differ across firms when implementing NPD processes? These design elements are strategic business unit (SBU) senior management involvement, business case content, customer interactions, and cross‐functional integration. What are the consequences of different combinations of NPD process design elements for innovation productivity? We explore these questions via a collective case study of newly implemented NPD process designs at three different SBUs of a major US‐based international conglomerate, 1 year after receiving the mandate to grow through innovation. Our analysis suggests that industry competitiveness and firm characteristics influence the NPD process design as SBUs employ distinct combinations of NPD design elements. The differential emphasis on design elements leads to variation in process design and divergence in innovation productivity. 相似文献

Michael G. Luchs K. Scott Swan Mariëlle E. H. Creusen 《Journal of Product Innovation Management》2016,33(3):320-341
The authors provide synthesized summaries of research on product design conducted over the 20‐year period from 1995 to 2014, as well as suggestions for future research. Building on the conceptual model of product design proposed by Luchs and Swan, the current project describes research findings based on a review of 252 articles drawn from eight of the academic journals most influential to marketing thought, and identified by their inclusion of the terms “product design” or “industrial design” within their abstracts, subject terms, and/or author supplied keywords. Specifically, the authors provide integrated summaries of 25 product design subtopics organized within Luchs and Swan's original 11 product design research topic categories, which, in turn, address the following three general product design research categories: context and strategy, product design process, and product design consequences. These summaries are followed by suggested future research opportunities to address gaps in the literature. In addition to seeking inspiration for future research based on a review of extant research, the authors illustrate an approach for exploring research opportunities based on current and emerging industry trends, such as sustainability, the sharing economy, and the emergence of consumer‐oriented health and performance management products. For each identified industry trend, the authors provide illustrative design implications with consequent illustrative research opportunities. This balanced approach to identifying near‐term research opportunities based on extant research and based on industry trends, i.e., looking forward and externally, may in turn improve the potential impact of future research on both knowledge development and on industry practice. 相似文献

Through a critical case study of the crash of American Airlines Flight 587, this paper draws upon ‘the Social Shaping of Technology’ (SST) approach to offer a reconceptualisation of the technology‐push and market‐demand model for High‐Reliably Organisations (HROs), providing support for a third factor, called here a ‘safety‐pull’. A safety‐pull is defined as organisationally supported reflexivity in which technology innovators and frontline operators collaborate to consider the potential implications of adopting new technologies in HROs and the complex ways this change may impact human operators' work performance, often in risky and unanticipated ways. In contrast to accidents occurring solely as the result of individual operator error, analysing the safety‐pull provides a way to tease out the wide range of factors that can contribute to HRO failures and offers a new SST perspective through which to examine high‐risk operations. 相似文献
