Certified Industrial Hygienist (CIH) The CIH exam spans occupational health across chemistry, biology, ergonomics, and regulatory frameworks? rarely contained within a single discipline. Prospective candidates should expect deep dives into exposure assessment methodologies, ventilation system design principles, and toxicology beyond surface-level definitions. A strong quantitative foundation helps; many questions require interpreting industrial hygiene data and selecting appropriate control strategies for real-world contamination scenarios.
