Since the early 1970s there has been a considerable growth in the literature published on the topic of human reliability. However, the main emphasis has been on technical aspects of human reliability, rather than on an integrated safety approach combining safety engineering, organization and human factors. Up till now, information on the subject of occupational safety which covers human reliability as one aspect has been widely scattered in technical reviews or briefly mentioned in textbooks.This book provides a comprehensive overview on occupational safety with special emphasis on the human element. Examples of empirical studies as well as suggestions for practical measures are included to help in the understanding and application of the contents of the text. Although the prime objective of the book is to cover occupational safety from a human factors point of view, nevertheless some of the related areas are also discussed. Among others, they include problem solving in complex systems, judgmental and heuristic biases in decision making as well as characteristics of decision support systems in high risk industry. The inclusion of these topics clearly indicates the shift in attention of occupational safety from work activities on the shop floor to tasks of operators and supervisors in automated and semi-automated systems.The text will prove useful to students of psychology and human factors engineering. Additionally, it holds great utility for persons with an engineering background, such as industrial engineers, quality control engineers, system and design engineers and safety practitioners.
