Industrial Hygiene Monitoring & Risk Assessment

A qualitative and quantitative industrial hygiene risk assessment evaluates workplace exposure to harmful substances to ensure compliance with occupational safety standards.

Qualitative Assessment

• Uses expert judgment to estimate exposure risks.
• Prioritizes high-risk hazards for further analysis.
• Expresses likelihood in terms like “low,” “moderate,” or “high.”

Quantitative Assessment

• Uses data and measurements to assess exposure levels.
• Compares findings to occupational exposure limits (OELs).
• Expresses exposure levels numerically (e.g., ppm, mg/m³).

When to Use Each Method

• Qualitative: Used for initial risk assessments and hazard prioritization.
• Quantitative: Used for detailed exposure evaluations and regulatory compliance.
