Qualitative Risk Assessment
Qualitative Risk Assessment methodologies include:
- What if/Safety Checklist: Structured session to identify process hazards for a series of "what if" scenarios. A safety checklist is used to ensure that all likely hazards are included in the review.
- Hazard Operability Analysis (HAZOP): A systematic group approach to identify and assess process hazards for specific processes in the system.
Regardless of the methodology used, the qualitative risk assessment process should include:
- Input from SMEs, workers and management
- Suggested controls (engineering and/or administrative) for each hazard identified.
A number of reference books are available which outline the What If/Checklist and HAZOP methodologies along with example systems.
