In IH, qualitative risk assessment is often used for what purpose?

• A. Used for final regulatory compliance decisions
• B. Used for initial hazard screening to prioritize hazards
• C. Used for precise exposure quantification
• D. Used for detailed quantitative risk assessment

Answer: (B)

Qualitative risk assessment in industrial hygiene is a quick, high-level way to judge which hazards deserve attention without needing detailed numerical data. It’s used to screen a range of hazards and rank them so you can focus resources on the most important ones. Typically this involves simple scales (for example high/medium/low) to judge both how likely an incident is and how severe the consequence would be, then combining those to prioritize risks.

This approach is ideal during the initial hazard screening phase because it helps you identify which hazards should receive more detailed evaluation or immediate controls, without waiting for exact exposure numbers. It guides where to gather data, what controls to implement first, and what warrants a deeper quantitative analysis later.

It’s not meant for final regulatory compliance decisions, which require formal documentation and standards-based evidence. It’s not for precise exposure quantification, which relies on measurements and numerical modeling. And it isn’t a detailed quantitative risk assessment, which produces numeric risk estimates rather than qualitative rankings.
