"The Associate Safety Professional (ASP) Exam - Essential Practice by Farcas and Cena is, as the name implies, an essential set of questions in Occupational Safety. This book is well laid out in 19 sections. It draws the reader in, which certainly assists with their increased retention of the amount of material that has to be covered. The questions are well introduced with a short narrative before presenting the pertinent equations and solution to the over 700 example essential questions. The book serves as a formidable preparation for the ASP exam and a good review of basic principles, a reference for many of the day-to-day technical issues confronting the practicing worker's safety, and a guide for raising awareness of potential problems for which alert action is required. The authors bring a breadth of experience and insight into the issues handled in the text. They bring context to the basic principles highlighted by the examples of the questions and their solutions. ASP Exam - Essential Practice should be a must-have text for everyone in the field." Michael McCawley, Ph.D., West Virginia University.
