Our Goal

You will pass the CIH exam. Our objective is to make this statement a reality. In my experience as a CIH Review instructor I have seen many talented and intelligent CIHcandidates sit for and fail the CIH exam, not because they weren't smart, but because they did not hone their test-taking skills through practice.

Mental Marathon

Preparing for the CIHexam is very much like preparing for a marathon. Taking practice exams is the equivalent of training by running and should be a regular (at least weekly) part of your study plan and schedule. This practice exam provides over 60 multiple-choice industrial ventilation practice questions for CIH candidates (two 30+ practice exams).

Ventilation

Ventilation is probably the most important engineering control available to industrial hygienists. It's also quite possibly the most important topic on the CIH exam. Its only rival for importance is toxicology.

Learning Objectives and Topics

As a result of using this course (both taking the practice exams and studying the solutions), you will be able to use many of the most common ventilation equations that could appear on the CIH exam, and you will gain a deeper understanding of industrial ventilation concepts. Some of the concepts include:

• Flow

• Velocity

• Duct area

• Velocity pressure

• Static pressure

• Total pressure

• Capture velocity

• Centerline velocity

• Hood types

• Fan laws (flow, pressure, power)

• Ventilation evaluation methods

Recommended Approach

We recommend taking the Ventilation Test 1, studying for one or more weeks, and then taking the Ventilation Test 2. Don't review the solutions after either. Later, after you've completed a substantial amount of studying, come back to and take both tests, and then carefully review the solutions for questions or solutions you don't understand.
