In industries such as oil & gas, petrochemicals, and manufacturing, safety is paramount. Ensuring the protection of personnel, assets, and the environment requires robust safety management processes. Two essential methodologies in this regard are Hazard Identification (HAZID) and Process Risk Assessments (PRA).
What is HAZID?
HAZID, or Hazard Identification, is a structured and systematic process used to identify potential hazards associated with industrial operations. It is typically conducted during the early design and engineering phases to mitigate risks before they escalate.
Objectives of HAZID:
- Recognize potential hazards and their sources.
- Assess the severity of identified hazards.
- Propose mitigation measures to eliminate or minimize risks.
What is Process Risk Assessment (PRA)?
Process Risk Assessment involves evaluating the risks associated with industrial processes. It provides a comprehensive understanding of potential failure scenarios, their consequences, and the likelihood of their occurrence.
Types of Process Risk Assessments:
- Qualitative Risk Assessment: Uses descriptive techniques like HAZOP (Hazard and Operability Studies) and FMEA (Failure Modes and Effects Analysis).
- Quantitative Risk Assessment (QRA): Provides numerical data on the probability of incidents and their impacts.
- Layer of Protection Analysis (LOPA): Evaluates existing safeguards and assesses if additional protection layers are necessary.

Differences Between HAZID and PRA
| Criteria | HAZID | PRA |
| Objective | Identify hazards | Assess and quantify risks |
| Phase of Application | Early design phase | Design, operation, and maintenance |
| Approach | Qualitative | Both qualitative and quantitative |
| Focus | Hazard recognition | Risk likelihood and consequence |
| Outcome | List of hazards and control measures | Risk profile and mitigation plan |
Importance of HAZID & PRA
- Enhanced Safety: Minimizes the risk of accidents and incidents.
- Regulatory Compliance: Supports adherence to industry standards and legal requirements.
- Cost Management: Reduces costs related to incidents, downtime, and repairs.
- Operational Efficiency: Facilitates smooth operations by identifying and mitigating potential hazards.
