Safety Professional's Reference and Study Guide
This is another excellent resource for the ASP and CSP exams. It provides detailed explanations of material most likely to be evaluated on the Safety Fundamentals and Comprehensive Safety exams. The one hesitation I have about the book is the heavy reliance on Wikipedia in the reference citations. The material is strong, and it contains a large collection of important information under one cover. I believe this is one of the best references available in preparation for the ASP and CSP exams.
