System safety concept overview

My first book, Safeware, presents a broad overview of what is known and practiced in System Safety today and provides a reference for understanding the state of the art. To avoid redundancy, information about basic concepts in safety engineering that appear in Safeware is not, in general, repeated. To make this book coherent in itself, however, there is some repetition, particularly on topics for which my understanding has advanced since writing Safeware. 

System Safety Engineering and Management, by Harold E. Roland and Brian Moriarty (1990) is a good but more involved book. It provides an extensive review of the concepts of system safety and their methods of application. An overview of a system safety program is given. The descriptions of several analytical techniques are valuable. For the application of some of them, quite a bit of knowledge about mathematics is necessary. 

As indicated previously, some introduction to the concept and method of PSSR at a given facility is often presented as part of a process safety management system new employee overview. But two major categories of personnel may benefit from special consideration - the first category is your facility s PSSR leaders and team members and the second is your management team and the remainder of the workforce. 

Our paper is organized as follows. The goal structuring notation is introduced in Sect. 2.1. In Sect. 2.2, we give a brief overview of ISO 26262. Our method is presented in Sect. 3. This section also describes our UML profile, which is used to express the functional safety concept. Based on this profile, we define the validation conditions. The tool support is outlined in Sect. 4. We introduce the illustrative example of an electronic steering column lock system as case study in Sect. 5. Section 6 presents related work, while Sect. 7 concludes the paper and gives directions for future work. 

Chapter Two, Error and Harm in Health Care, departs momentarily from the patient safety manifesto, as already mentioned, to provide background knowledge on current research in patient safety, the patient safety movement to date, and the reasons why today s health care system is so error-prone. Chapter Three, Understanding the Basics of Patient Safety, provides an overview of basic concepts and terms in the science of patient safety. These concepts and terms fe>rm the foundational touchpoints of the book. 

While the fundamental concepts of a safety management system can be the same, we will discuss in Chapter 5, Overview of Basic Safety Management Systems , how it is deployed and sustained will vary based on the organization s culture. Program elements, safety-related... 

As issues with the current safety culture and the safety management system are identified, the PDCA/DMAIC concepts provide a framework for administration of the safety management system elements. Refer to Figure 6.2 for an Overview of the DMAIC and the PDCA Processes Relationship . 

Patient safety is a major concern in health care systems worldwide and has gained increasing attention since the Institute of Medicine published its report To Err Is Human in 1999 [1]. Based on extrapolations of study data, this report estimated that approximately 44,000-98,000 Americans die annually due to adverse events in health care. Patients with serious conditions, multimorbidity, and with intense and fragmented health care utilization, like end-stage renal disease (ESRD) patients, are at increased risk for suffering adverse events. It is thus vital that clinicians caring for ESRD patients make patient safety a top priority and cooperate on safety with their colleagues within and across other clinical specialties inside and outside the hospital. In this chapter, we will introduce the fundamental terms and concepts of patient safety and present readers an overview of essential data. We describe examples of important innovations which contribute to patient safety and briefly discuss future needs and developments. 

In Chapter 1 we introduce the concept of SHE (safety, health and environment) information systems. It will provide a frame of reference in our subsequent analysis of the different tools and methods used in accident control through experience feedback. We make a comparison with the human information processes and identify basic similarities and differences. Chapter 2 gives an overview of different boundary conditions of a SHE information system, both inside and outside a company. Chapter 3 introduces four different approaches in safety practice and describes how these will contribute in subsequent parts of the book to our understanding of how to prevent accidents. In Chapter 4 we will look into a case from the environmental field. It demonstrates a successful application of basic principles of experience feedback in the reduction of emissions from a fertiliser plant. We use this example to present some of the issues dealt with in later parts of the book and demonstrate how they form a coherent whole. 

The IAEA s Technical Reports Series No. 387 [4] presents an overview of concepts and examples of systems discussed in this Safety Guide and may provide useful background material for some users. 

Hazard and associated risk controls and mitigation should be supported by a safety system that incorporates core human behavioral concepts. The following discussion provides an overview of the basic elements of human behavior and how to apply them to the workplace. 

In addition to the hazard, risk recognition, and JHA development concepts, a brief overview of Six Sigma tools is provided for use as part of a continuous improvement effort for a safety system. Many different uses of specific tools such as diagrams, charts, analysis techniques, and methods provide step-by-step help to estabhsh a process that can continually improve.
