— WHAT IS HAZOP —
HAZOP Study —
What It Is & Why It's Required
A HAZOP (Hazard and Operability Study) is a structured, systematic examination of a process design to identify hazards and operability problems. Conducted by a multi-disciplinary team using guide words applied to process parameters, HAZOP is the most widely used Process Hazard Analysis (PHA) methodology for chemical and process industries worldwide — and is mandated by MSIHC Rules 1989 for Gujarat industries handling hazardous chemicals above threshold quantities.
MSIHC Rules 1989 — MHI Mandatory
Major Hazard Installations (MHI) handling Schedule 1 chemicals above threshold quantities must conduct HAZOP or equivalent PHA. DISH Gujarat inspects MHI compliance including current HAZOP documentation.
MoEFCC EC Compliance Requirement
MoEFCC Environmental Clearance conditions for chemical/petrochemical projects typically require PHA/HAZOP as a pre-commissioning condition. EC renewal may require HAZOP revalidation.
Pre-Startup Safety Review
HAZOP conducted before plant startup identifies design deficiencies when changes are least costly — far cheaper than post-incident modifications or insurance claims from process accidents.

— WHAT YOU GET —
Every HAZOP Study Includes
From P&ID review to DISH Gujarat–ready reports — a complete process safety deliverable.
Pre-HAZOP P&ID Review
Thorough review of P&IDs, process descriptions, and operating procedures before sessions — ensuring all nodes are correctly identified and documentation gaps are addressed before starting.
Expert HAZOP Facilitation
Experienced HAZOP facilitator leads systematic multi-disciplinary team examination — guiding the team through guide words, capturing deviations, causes, consequences, and safeguards.
Comprehensive Risk Analysis
Full cause-consequence analysis for every identified deviation. Risk ranked using client-specific risk matrix (likelihood × severity). All credible major accident scenarios identified.
Safeguard & IPL Review
Existing IPLs (Independent Protection Layers) assessed for adequacy and reliability. Identification of safeguard gaps and recommendations for additional controls — procedural, hardware, or SIS.
DISH Gujarat–Compliant Report
HAZOP study report in DISH Gujarat–accepted format with all worksheets, node drawings, risk matrix, and action register. Suitable for MHI Safety Report and MSIHC renewal submissions.
Action Register & Tracking
Colour-coded action register with responsible person, risk priority, and target dates. Follow-up close-out verification available. HAZOP revalidation scheduled per MSIHC 5-year requirement.
Consequence Modelling (Optional)
PHAST/SAFETI consequence modelling for toxic releases, fire, and explosion scenarios identified in HAZOP. Dispersion plots, radiation contours, and overpressure maps for high-risk scenarios.
MOC & Revalidation Support
Management of Change (MOC) assessments for process modifications. HAZOP revalidation every 5 years or post-incident, documenting changes since previous study and new scenarios identified.

— OUR PROCESS —
HAZOP Study Process — Step by Step
Our 6-step HAZOP methodology follows IEC 61882, MSIHC Rules requirements, and DISH Gujarat documentation standards.
Pre-HAZOP Preparation
Collection and review of P&IDs, PFDs, process descriptions, operating procedures, MSDSs, equipment datasheets, and MSIHC consent conditions. Node division based on process sections, operating phases (startup, normal, shutdown, emergency), and utility systems.
HAZOP Team Formation
Formation of multi-disciplinary HAZOP team including process engineer, safety specialist, instrumentation engineer, operations representative, and maintenance lead. Prism's HAZOP facilitator leads the structured examination to ensure systematic coverage of all deviations.
Node-by-Node Examination
Systematic examination of each process node using standard guide words (No, Less, More, Reverse, Other Than, As Well As, Part Of) applied to process parameters (flow, pressure, temperature, composition, level) to identify all plausible deviations from design intent.
Cause-Consequence Analysis
For each identified deviation, the HAZOP team systematically identifies all plausible causes (equipment failure, human error, utility failure, external events) and consequences (fire, explosion, toxic release, environmental damage, business interruption). Risk ranking applied per client matrix.
Safeguard Assessment & Recommendations
Existing safeguards (IPLs — Independent Protection Layers) reviewed for adequacy against each identified scenario. Where risk exceeds acceptable level, actionable recommendations generated — design changes, additional instrumentation, procedural controls, or SIL-rated safety functions.
HAZOP Report & Action Register
Comprehensive HAZOP report in DISH Gujarat and regulatory-acceptable format: study methodology, node descriptions, worksheets with all deviations/causes/consequences/safeguards, recommendations, action register with responsible persons and target dates. Available for MSIHC renewal and EC compliance submissions.

What Our HAZOP Clients Say
Prism conducted HAZOP for all 12 nodes of our distillation unit. The team's process chemistry knowledge and PHA methodology were outstanding. The final HAZOP report with action tracker was comprehensive and accepted by DISH Gujarat without revision. Highly recommended for any MSIHC facility.
For our EC renewal, MoEFCC required an updated HAZOP study. Prism's team understood pharmaceutical synthesis processes — their deviation analysis identified 3 critical safeguard gaps in our reactor system that we had missed. Their final report sailed through MoEFCC technical scrutiny.
We had a HAZOP conducted by Prism for our new chlor-alkali plant prior to commissioning. Their systematic node-by-node analysis identified issues with our brine recycle loop that the design team had not flagged. Worth every rupee spent before startup.
