Quantitative risk assessments cannot eliminate risk, nor can they resolve trade-offs. They can, however, guide principled risk management and reduction - if the quality of assessment is high and decision makers understand how to use it. This book builds a unifying scientific framework for discussing and evaluating the quality of risk assessments and ...

Treated briefly in this chapter are the methods that allow quantification of the probability of a particular type of accident occurring. It is not enough simply to identify all possible types of accidents, their causes and their evolution sequences. Neither is it sufficient to be able to predict the effects of an accident, assuming a specific group of ...

QRAS—the quantitative risk assessment system
Reliability Engineering & System Safety, 2006This paper presents an overview of QRAS, the Quantitative Risk Assessment System. QRAS is a PC-based software tool for conducting Probabilistic Risk Assessments (PRAs), which was developed to address risk analysis needs held by NASA. QRAS is, however, applicable in a wide range of industries.

Asbestos Exposure —Quantitative Assessment of Risk
American Review of Respiratory Disease, 1986Abstract Methods for deriving quantitative estimates of asbestos-associated health risks are reviewed and their numerous assumptions and uncertainties described. These methods involve extrapolation of risks observed at past relatively high asbestos concentration levels down to usually much lower concentration levels of interest today −

A method for quantitative risk appraisal for pesticide risk assessments
Journal of Toxicology and Environmental Health, Part A, 2016Pesticide risk assessments are fraught with uncertainties that arise from the process of estimating exposure to and toxicity of chemicals. Regulatory agencies resolve those uncertainties in a health-protective (conservative) manner, typically acknowledging only inter- and intraspecies uncertainties quantitatively.

Quantitative Risk Assessment: State-of-the-Art for Carcinogenesis
The American Statistician, 1983A critical evaluation of the use of statistical models in carcinogenic risk assessment is made with emphasis on the strengths and weaknesses of current practice. The objective is to bring together information from the fields of toxicology and statistics to develop a sound scientific basis for making risk decisions. It is emphasized that risk assessment

Quantitative risk assessment: Qualms and questions
Teratogenesis, Carcinogenesis, and Mutagenesis, 1988AbstractWithin the past ten years, quantitative risk assessment has come to play a central role in the federal regulation of carcinogens. Federal agencies use quantitative risk both to set priorities and to establish exposure levels. The use of quantitative risk assessment is mandated by Executive Orders requiring performance of cost‐benefit analysis ...

Qualitative and quantitative risk assessment
Food Control, 1999Abstract Risk assessment and HACCP are related, but fundamentally different processes. Four major elements of risk assessment are commonly described (hazard identification; exposure assessment; dose-response assessment or hazard characterization; and risk characterization).

Quantitative Risk Assessment for Developmental Toxicity
Biometrics, 1992Pharmaceutical companies and governmental regulatory agencies are becoming increasingly aware of the need for improved statistical methods for developmental toxicity experiments. Although a number of statisticians have become interested in this area, activity has centered mostly on the development of methods to analyze binary outcomes, such as ...

Risk Assessment in Genetics: A Semi-quantitative Approach
2001Public awareness of genetic predisposition to diseases such as breast cancer threatens to put severe strain on genetics services. Computer-based decision support for general practitioners (GPs) has the potential to reduce unnecessary referrals, but issues of communicating about levels of risk and uncertainty must be addressed.
