CIH EXAM Equations simply explained and with examples
Dr. Daniel Farcas, CIH, CSP, CHMM wrote this book to help those preparing for the Certified Industrial Hygienist (CIH®) exam. Its easy-to-understand manner will help you with the fundamental equations used in the exams’ formulas and grasp the basic concepts of the calculations. As the title says, each formula is simply explained with detailed examples.
Fundamentals of Industrial Hygiene
Modern Industrial Hygiene Volumes 1, 2, and 3
Volumes 1 and 2 have been available in the past, but I've been hesitant to recommend the texts prior to the release of volume 3. They were somewhat incomplete. The series has one more volume to go with the evaluation of physical hazards, and I am looking forward to the release of volume 4 as well. However, I believe the first three volumes provide enough of a firm foundation in the practice of industrial hygiene and preparation for the Board for Global EHS credentialing Certified Industrial Hygienist (CIH) exam.
Volume 1 focuses on recognizing, evaluating, and controlling chemical agents. Topics include an overview of industrial hygiene and diseases in the workplace, as well as tools and methods for assessing workplace hazards.
Volume 2 provides insight into the biological aspects of industrial hygiene. It includes chapters on the respiratory system, dermal exposures, ergonomics, epidemiology, and biological agents. This is a good occupational toxicology text, as well as an instruction manual on how to evaluate biological hazards.
Volume 3 is devoted to controlling the hazards of chemical agents. The main focus is on ventilation, but it also reviews respiratory protection and personal protective equipment, as well as describing administrative risk management tools.
We believe Modern Industrial Hygiene is the highest quality comprehensive text for industrial hygiene on the market today. The series provides basic information on most industrial hygiene topics and is relatively easy to read. We do not recommend purchasing if you have a good library or already own The Industrial Environment: Its Evaluation and Control.
