In this companion to his Safety Management: A Human Approach, consultant Petersen provides a systems approach (with reactive and proactive elements) to occupational safety. He is uncertain whether the passage of OSHA and related legislation since previous editions (1971, 1978) has enacted changes for the better or worse. The author is more sanguine about managers' embrace of behavioral research, which prompted this update, along with costly disasters such as Bophal and Chernobyl. Includes new sections on trends, ergonomics, and Statistical Process Control. Annotation copyrighted by Book News, Inc., Portland, OR
