Case Study: Process Safety – HAZOP Study
Training Topic: Process Safety – HAZOP Study<br>Trainer: Yashpal Singh, (Joint Secretary, National Safety Council – North Zone Chapter)<br>Organized By: National Safety Council – North Zone Chapter<br>Audience: EHS Professionals, Process Engineers, Safety Officers<br>Training Type: Classroom / Workshop-Based Training
Background
Process industries face significant risks arising from design deviations, operational upsets, and equipment failures. To systematically identify and control such risks, Hazard and Operability Study (HAZOP) is widely recognized as a critical Process Hazard Analysis (PHA) technique.
Recognizing the need to strengthen process safety competence among industry professionals, the National Safety Council (NSC), North Zone Chapter organized a dedicated training program on Process Safety – HAZOP Study.
As part of this initiative, Yashpal Singh was invited to deliver the HAZOP training, focusing on fundamentals, methodology, regulatory expectations, and hands-on application. The session emphasized not only theoretical understanding but also practical group-based learning using real P&IDs.
Training Objectives
The training aimed to:
- Explain why HAZOP is required in process industries
- Build strong fundamentals of process safety and PHA
- Enable participants to understand and apply the HAZOP methodology
- Improve capability to identify causes, consequences, safeguards, and risks
- Promote effective team-based HAZOP studies through group activities
Training Coverage
The session covered comprehensive Process Safety and HAZOP content, including:
- Why HAZOP is required
- Introduction to HAZOP
- Legal requirements and references related to HAZOP
- Fundamentals of Process Safety
- Process Hazard Analysis (PHA)
- HAZOP Methodology – Concepts and Principles
- Identifying causes
- Evaluating consequences
- Safeguards and risk assessment
- Recommendations and limitations of HAZOP
- HAZOP team roles and responsibilities
- Appropriate stages for performing HAZOP
- HAZOP preparation and documentation – Terms of Reference (TOR)
- Planning a HAZOP study
- Advancements and future trends in HAZOP
Group Discussion & Practical Activity
A key highlight of the training was the interactive group exercise, designed to simulate a real HAZOP workshop.
Trainer’s Briefing
- Process explanation by the trainer (5–10 minutes)
Group Formation
- 4 groups formed by the trainer
- Each group consisted of 7–8 participants
Discussion & Presentation
- 20 minutes allotted for group discussion
- 5 minutes per group to present findings
- One participant selected as group presenter
Materials Provided
- Printed P&IDs distributed to each group
Group Activities
- Group 1: Mark nodes on P&ID and write node descriptions
- Group 2: Prepare HAZOP worksheet
- Parameter: Pressure
- Guidewords: High / Low
- Group 3: Prepare HAZOP worksheet
- Parameter: Level
- Guidewords: High / Low
- Group 4: Prepare HAZOP worksheet
- Parameter: Flow
- Guidewords: More / Less
This activity helped participants experience actual HAZOP team dynamics and documentation practices.
Course Material
- Process and Machine Safety course material was shared with all participants
- The Process Safety content was prepared by HSE-RMS and published by NSC
- Machine Safety topics were delivered by another subject expert
- The shared material aligned fully with the process safety and HAZOP topics covered during the session
Learning Outcomes
After the training, participants were able to:
- Understand process safety fundamentals and HAZOP purpose
- Apply the HAZOP methodology step by step
- Identify deviations, causes, consequences, and safeguards
- Participate effectively in multi-disciplinary HAZOP teams
- Prepare and review HAZOP worksheets and documentation
- Conduct more structured and defensible HAZOP studies
Value Delivered
- Improved HAZOP competency among participants
- Strong linkage between theory and practical application
- Enhanced understanding of team-based hazard analysis
- Better preparedness for audits and regulatory expectations
- Access to standardized, NSC-published course material
Conclusion
The Process Safety – HAZOP Study training delivered by Yashpal Singh for the National Safety Council, North Zone Chapter successfully strengthened participant capability in systematic hazard identification and risk assessment.
Through a combination of technical lectures, structured methodology, and hands-on group activities, the program enabled professionals to apply HAZOP effectively in real industrial environments. This initiative aligns with the broader mission of HSE Process Safety Academy (HSE-PSA) to promote practical, standards-aligned, and industry-relevant process safety education.
