CIH Reference Materials

Additional study and reference materials recommended by our instructors

Bioaerosols: Assessment and Control

This is a good text covering IH issues for bacteria, viruses, and fungal species. Many IHs find themselves working with mold-related issues. Another good reference source.

CIH EXAM Equations simply explained and with examples

An easy-to-understand text to help you understand the fundamental equations used in the CIH® exam formulas. 

Fundamentals of Industrial Hygiene

Provides very basic information on most industrial hygiene topics. Relatively easy read. Do not recommend purchasing if you have a good library or already own The Industrial Environment: Its Evaluation and Control.


Haz-Map is an occupational health database designed for health and safety professionals and for consumers seeking information about the health effects of exposure to chemicals and biologicals at work.

Industrial Hygiene Reference & Study Guide

We call this the "Little White Book." It is a short list of facts and information on each industrial hygiene subject. It is great for reviewing information, but it won't help much if you haven't studied the material in another text.

Industrial Ventilation: A Manual of Recommended Practice for Design

The basic reference for ventilation. We recommend reading the first five chapters. You can pass the exam without owning this manual, but you will probably want a copy if you stay in the field for any length of time.

Modern Industrial Hygiene Volumes 1, 2, & 3

The most comprehensive texts available on the current practice of industrial hygiene. Dr. Perkins has done an excellent job of editing the text so that there is minimal or no duplication between the chapters by the various authors. The contributors and reviewers did a fantastic job of presenting the material in a clear and precise manner. The texts present technical information important to the practicing industrial hygienist in a straightforward manner.

Radiation Protection: A Guide for Scientists and Physicians

A great text on radiation. Good reference book for your library, but probably not the best investment in studying for the exam.

Recognition of Health Hazards in Industry: A Review of Materials and Processes

A great book describing health hazards in a variety of industries. Describes many of the industries where IH really got a strong start. Many of us no longer work in these industries, but there are still questions on the exam based on prevalent exposures in specific businesses. Recommend reading chapters on welding, abrasive blasting, and surface coatings.

Safety Management: A Human Approach

This is the first real safety management book that I've read. It is well written, and it is definitely worth reading if you are a safety professional or industrial hygienist. Many of the management theories are discussed in the text. This is an excellent book.

The Cartoon Guide to Statistics

A great guide for statistics. Well written and easy to read. Very helpful for people with difficulty understanding statistical concepts.

The Dose Makes the Poison

A new favorite toxicology text. Written in a clear and understandable style with the general public in mind, this book is an excellent introductory guide to the history, concepts, and practice of toxicology.

The Industrial Environment - Its Evaluation and Control

This is considered to be the original "White Book." It was originally published by NIOSH and has been updated twice by the AIHA.

The Noise Manual

The basic text for noise and hearing protection. It is a good investment for your IH library, but not absolutely necessary for the exam.

TLVs and BEIs: Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices

A must have. Excellent source of information regarding the CIH exam. Recommend reading it cover to cover. Don't try to memorize TLVs, but you should understand the basis for TLVs. It also provides information on many IH subjects.

Toxicology Principles for the Industrial Hygienist

This book provides an in-depth review of toxicology. It is an excellent source of information on a difficult subject for the exam.
