Certified Occupational Health Air Quality Specialist (COHAQS) Industrial hygienists pursuing COHAQS (Certified Occupational Health Air Quality Specialist) face a curriculum uniquely grounded in real-world sampling methodologies?gravimetric analysis, optical microscopy, and direct-reading instruments?rather than theory alone. The exam integrates EPA regulations, OSHA standards, and NIOSH protocols into scenario-based questions that mirror actual workplace investigations, distinguishing it from generalist certifications that treat air quality as peripheral to broader safety concerns.
