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.
