Overview of Risk Assessment

The risk assessment is a primary component of the risk management process. The objective of a risk assessment is to identify risks to organizational assets and propose an achievable level of protection that is commensurate with the level of risk, without exceeding that level of risk so that it will be cost effective. Risk is a function of the values of threat, vulnerability, and collateral damage via loss occurrence. The objective of risk management is to create a level of protection that mitigates vulnerabilities to threats and their potential consequences, thereby reducing risk to an acceptable level. Ideally, all risk would be eliminated. However, in practicality the elimination of risk is not feasible (Department of Homeland Security, 2008). 

The process of risk assessment will not prevent adverse events from occurring however, it enables the safety manager to focus on those things that are likely 

The methodology mnst be credible, and it must assess the threat, consequences, and vnlnerability to a specihc loss event. 

The methodology mnst be reprodncible, and it must produce similar or identical resnlts when applied by various safety professionals. 

The methodology must be defensible, and it must provide sufficient justification for deviation from the baseline.

The series of Risk Assessment Guidelines includes a guideline for neurotoxicity risk assessment (US-EPA 1998). This Guideline sets forth principles and procedures to guide US-EPA scientists in evaluating environmental contaminants that may pose neurotoxic risks, and inform US-EPA decision-makers and the public about these procedures. The Guideline includes a discussion of general dehnitions and issues, an overview of test methods, and the interpretation of data within the U.S. framework for risk assessment. 

REPROTOX is useful clinically. It provides succinct, authoritative overviews of the reproductive and developmental toxicity of a large number of chemical exposures, including many important occupational exposures. The system is designed for use by health professionals who are familiar with the general principles of risk assessment and is intended to assist in the counseling of individual patients. 

Answering to these calls, the aim of this paper is to provide a broad overview and analysis of how risk has been defined, and what risk perspective is taken in methods for risk assessment of maritime transportation. Our main interest is a number of risk-theoretic aspects, related to the underlying conceptualizations, perspectives and principles in the sense intended by Aven (2012a). Reflecting on foundational issues in the application area of risk assessment in maritime transportation requires a methodological framework. Two aspects of this framework are introduced in Sections 2 and 3, respectively addressing the risk concept (what risk is ), and the risk perspective (how risk is looked at ). While these aspects are closely linked in practical applications, making a clear distinction between these is important from a foundational viewpoint. 

Chapter 4 focuses on techniques which are applied to a new or existing system to optimize human performance or qualitatively predict errors. Chapter 5 shows how these teclmiques are applied to risk assessment, and also describes other techniques for the quantification of human error probabilities. Chapters 6 and 7 provide an overview of techniques for analyzing the underlying causes of incidents and accidents that have already occurred. 

In addition, the chapter will provide an overview of htunan reliability quantification techniques, and the relationship between these techniques and qualitative modeling. The chapter will also describe how human reliability is integrated into chemical process quantitative risk assessment (CPQRA). Both qualitative and quantitative techniques will be integrated within a framework called SPEAR (System for Predictive Error Analysis and Reduction). 

This chapter has provided an overview of a recommended framework for the assessment of human error in chemical process risk assessments. The main emphasis has been on the importance of a systematic approach to the qualitative modeling of human error. This leads to the identification and possible reduction of the human sources of risk. This process is of considerable value in its own right, and does not necessarily have to be accompanied by the quantification of error probabilities. 

The characteristics of the applied models have been described in detail in the chapters Environmental Fate Models [50] and A Revision of Current Models for Environmental and Human Health Impact and Risk Assessment for Application to Emerging Chemicals [49] and only a brief overview is given here. Since each model has its own approach (i.e., QWASI is focused on the aquatic system), the combined results are expected to give a wider view with in-depth analyses for different aspects compared to just one model with its special characteristics. 

In addition to an overview of government regulations, the book introduces the resources of the AICHE Center for Chemical Process Safety library. Guidelines are offered for hazard identification and risk assessment. The book concludes with case histories drawn directly from the authors experience in the field.

An overview is provided of ongoing risk assessments on halogenated phosphate ester flame retardants in Europe. On the basis of the so-called second and fourth Priority lists on Existing Chemicals (Council Regulation No793/93) three chlorinated phosphate ester flame retardants are selected. The selection is based on their hazard profile, volume and use pattern. The three substances involved are TCPP, TDCP and TCEP (Antiblaze V6 from Albemarle is also involved but, due to confidentiality, is not discussed. An outline is provided from a European point of view on topics such as methodology of risk analyses, data-gaps and worst case approach, industry involvement, downstream participation and possible impact of final report on industry. 2 refs. 

An Overview of Quantitative Methods for Assessment and Evaluation of Chemical Risks... 

The first edition1 of this book was published approximately 13 years ago. Its primary objective was to present an overview and a "roadmap" of the process of new drug discovery and development, particularly oriented to individuals or companies entering the pharmaceutical field. It was written by one of the authors (Smith), with no contributors, and drawn on Smith s experiences in the industry and field over the course of nearly 40 years. In the second edition, the scope of the first book has been expanded and technical details in the form of hard data have been included. In addition to the editors own commentary and contributions, the major part of the book is the result of contributions of experts in the industry. New chapters on risk assessment, international harmonization of drug development and regulation, dietary supplements, patent law, and entrepreneurial startup of a new pharmaceutical company have been added. Some of the important, basic operational aspects of drug discovery and development (e.g., organizational matters, staff requirements, pilot plant operations, etc.) are not repeated in this book but can be found in the first edition.
