HAZOP (Hazard and Operability) Training

A HAZOP workshop can be one of the most powerful safety tools in a high-hazard facility… or it can be a painful meeting that produces a long spreadsheet nobody uses. The difference is competence: the team needs to understand design intent, how deviations are generated, how guidewords are applied to P&IDs, and how to turn discussion into clear, defensible recommendations.

That’s exactly what our HAZOP training is built for.

At MHI Risk Engineers, our HAZOP (Hazard and Operability) Training builds deep competence in facilitating and participating in effective hazard studies using international best practices. It’s practical, hands-on, and designed for real industrial environments where the stakes are high.

This course supports organisations conducting formal HAZOP studies, Layer of Protection Analysis (LOPA) and Safety Instrumented Systems (SIS) assessments within Major Hazard Installation (MHI) environments in South Africa.

Who this course is for

HAZOP training is ideal for:

If your team sits in hazard studies but struggles with consistency, clarity, or decision-making, this training will tighten that up quickly.

Learning outcomes (what you’ll be able to do)

Participants gain practical understanding of how HAZOP outputs feed into LOPA, Quantitative Risk Assessment (QRA) and SIS design decisions.

01

Understand design intent and deviation principles

You’ll learn how a HAZOP study is built on design intent and how deviations are systematically generated — not guessed.

02

Apply HAZOP guidewords to P&IDs

We focus heavily on using guidewords properly (e.g., No, More, Less, Reverse, Other than) on Piping & Instrumentation Diagrams (P&IDs) and defining logical nodes.

03

Team roles, facilitation techniques, and tools

You’ll understand:

  • the roles of facilitator, scribe, and discipline representatives

  • how good facilitation keeps the workshop structured and productive

  • how software tools can support documentation and action tracking (without replacing good facilitation)

04

Integrate HAZOP with SIL determination and LOPA

We show how HAZOP outputs feed into:

SIL determination and safety instrumented function decisions
This is where many organisations lose the thread — and where good integration makes hazard studies far more valuable.
LOPA (Layer of Protection Analysis)

05

Hands-on workshops using realistic case studies

This course includes practical workshop sessions so learners don’t just “understand” HAZOP — they can actually do it.

Relevant standards and best practice

We align the training with recognised international guidance, including:

What you get after the course

Depending on your needs, you can expect:

The training references IEC 61882 for HAZOP methodology and integrates principles aligned with IEC 61511 and South African MHI regulatory requirements.

Strengthen your hazard study capability

If you want HAZOP workshops that are structured, efficient, and consistently high-quality, HAZOP training is the fastest way to build that capability across engineering, operations, and HSE.

FAQ: HAZOP Training

What is HAZOP training?

HAZOP training teaches people how to participate in and/or facilitate a Hazard and Operability Study using a structured method. It covers design intent, deviation generation, guideword application, node selection, documentation quality, and how to turn findings into practical recommendations.

HAZOP stands for Hazard and Operability (Study). It’s a systematic technique used to identify hazards and operability problems in process systems.

There isn’t one universal “qualification” that makes someone competent at HAZOP. Competence typically comes from:

  • a relevant technical background (process/ops/instrumentation/maintenance/HSE)

  • understanding the HAZOP method and standards

  • practical workshop experience

for facilitators: strong facilitation skills and consistent documentation discipline
HAZOP training gives the method foundation and practice exposure; competence is built further through real studies.

A simplified HAZOP workflow looks like this:

  1. prepare scope, documents (P&IDs), and design intent

     

  2. split the system into nodes

     

  3. apply guidewords to parameters to generate deviations

     

  4. identify causes, consequences, and existing safeguards

     

  5. decide if risk is acceptable; recommend actions where needed

     

  6. assign actions, owners, and due dates

     

  7. follow up and close out actions with verification

It depends on scope and complexity. A small system might take a day or two; complex facilities and full project studies can take multiple days or weeks in phases. Duration is influenced by:

  • number of nodes and P&IDs

  • quality of preparation and documentation

  • team availability and decision-making speed

complexity of safeguards and follow-up requirements

  • SAMTRAC pricing varies by provider and whether it’s online, part-time, or classroom-based. If you share the provider you’re comparing, we can benchmark it — but for this page, the key point is that SAMTRAC is a broader safety qualification, while HAZOP training is a specialist process hazard study capability.

A common way to group hazards is:

  • physical/safety hazards

     

  • chemical hazards

     

  • biological hazards

     

  • ergonomic hazards


Some frameworks also include psychosocial hazards. In process industries, fire/explosion and toxic release hazards often sit within physical/chemical categories but deserve focused attention.

Example: A line is designed to deliver cooling water to a reactor (design intent: maintain temperature).
Deviation: No flow (guideword “No”).
Possible causes: pump trip, valve closed, blockage.
Consequence: temperature rise → runaway reaction risk.
Safeguards: temperature alarm, interlock shutdown, redundant pump.
Recommendation: improve interlock logic / add proof testing / ensure procedures prevent valves being left closed.

A practical grouping is:

  • qualitative

     

  • semi-quantitative

     

  • quantitative

     

  • dynamic/continuous


HAZOP is primarily a qualitative hazard study method, but it can feed into semi-quantitative and quantitative methods like LOPA and QRA.

“OHS course” can mean many different courses (short courses, certificates, diplomas). Duration depends on the provider and level. HAZOP training is typically shorter and highly specialised compared to general OHS programmes.

They serve different purposes. Generally:

  • IOSH is often positioned as a practical introductory/operational safety qualification

  • NEBOSH is widely recognised internationally and can be more rigorous depending on the level
    Neither replaces specialist process safety training like HAZOP; they complement it.

  • A practical seven-step hazard analysis flow is:

    1. define scope and boundaries

    2. gather information (P&IDs, procedures, design intent)

    3. identify hazards and deviations

    4. identify causes

    5. identify consequences

    6. evaluate safeguards and risk acceptability

    7. recommend improvements and track closure

Effective HAZOP studies form the foundation of structured risk management in high-hazard industries. This training strengthens facilitator competence and supports defensible hazard analysis across industrial facilities in South Africa.
