What to know before the study, how to prepare, what to do during the workshop, and how to follow up effectively.
Hazard and Operability studies (HAZOPs) are one of the most widely used methods for identifying hazards and improving process safety in high hazard industries. HAZOP training usually focuses on the technical aspects of the study: establishing nodes, deviations, safeguards, and defining the facilitator’s role.
While the workshop itself is often the most visible part of the process, a successful HAZOP depends just as much on what happens outside the technical discussions — the planning, coordination, and post-study follow-up that keep the process moving and ensure it delivers value. These activities are sometimes treated as administrative tasks on the periphery of the study and are often picked up on the job rather than taught directly. However, they are critical not only to the success of the HAZOP itself, but also to ensuring that its outputs, decisions, and associated data are captured accurately for future reference.
This guide is designed for anyone stepping into the HAZOP Project Manager role — or managing a HAZOP process for the first time. You do not need to be a technical specialist to manage a HAZOP effectively, but you do need to understand how the process works and what is required at each stage. It covers the following topics:
Who is a HAZOP Project Manager?
A HAZOP Project Manager is a person responsible for planning, coordinating, and managing a HAZOP study to ensure it delivers its intended outcomes.
This role is not always a defined role within a project — the role could be assigned formally or informally to a project engineer, design engineer, or a traditional project manager, or split between a number of people. However, every HAZOP needs to be planned and managed to ensure the study runs smoothly and achieves its objectives, and whoever is responsible for that is the HAZOP project manager.
Regardless of the person’s regular role, the HAZOP Project Manager is the bridge between the technical team involved in the HAZOP workshop and the broader project goals. They don’t need to be a technical specialist, but they do need to understand how the process works and what is required at each stage.
What all HAZOP Project Managers Should Know
Before you schedule your first HAZOP, it helps to understand what the Project Manager role actually involves. The Project Manager is not there to lead the technical discussion or make technical decisions on behalf of the team. The Project Manager’s role is to coordinate the process, connect the right people, and make sure the study is set up to run effectively from planning through to action close-out.
That means understanding not only what happens during the workshop, but also what needs to happen before it starts and after it finishes. Having that wider view early will make the rest of the process much easier to manage.
Here are five practical tips to help you understand what you need to know before you dive in.
1. You don’t need to be a HAZOP expert
A common concern for first-time HAZOP Project Managers is whether they need to be highly technical to do the role well.
In most cases, the answer is no. You do not need to be involved in identifying hazards, challenging safeguards, or leading the technical discussion in the room. That is the role of the facilitator and study participants.
What you do need is a working understanding of how a HAZOP is structured, what the study is trying to achieve, and what inputs and outputs are required at each stage. The more familiar you are with the process, the easier it will be to plan effectively, coordinate the right resources, and ask the right questions at the right time.
2. The design lead is your ally
One of the most important working relationships you will have during a HAZOP is with the design lead.
They will often be your main source of information on design maturity, technical documentation, discipline input, and project priorities. Building a strong relationship early makes it much easier to understand when the study should take place, what information will be available, and who needs to be involved.
A good design lead can help you sense-check timing, identify gaps in readiness, and keep the wider technical team engaged. In practice, they are often one of your most valuable partners in getting the study set up properly.
3. Understand facilitation capability early
Facilitation is a critical part of a successful HAZOP, so it is important to establish early how this will be delivered.
Some organisations have internal HAZOP facilitators and scribes available, while others rely on external support. Either approach can work well, but the key is to understand what is available, who is suitable, and whether they can support your required timescales. If an external facilitator is needed, this may affect procurement, budgets, scheduling, and preparation activities.
Identifying this early helps avoid unnecessary delays and gives everyone more time to align on scope, expectations, and deliverables.
4. Timing is critical
Choosing the right time to run a HAZOP can have a major impact on its effectiveness.
If the study is scheduled too early, the design may not be developed enough for the team to carry out an effective analysis. That can lead to wasted workshop time, unnecessary actions, and avoidable rework later in the project. If the study is scheduled too late, there may be limited opportunity to implement changes without affecting cost or programme schedules.
The goal is to find the point where the design is mature enough to support meaningful review, but still flexible enough for recommendations to be addressed efficiently. This is something that should be discussed early with the design lead and other key stakeholders.
5. Project management continues after the workshop
For many first-time Project Managers, the workshop can feel like the main event. In reality, it is only one part of the overall HAZOP process.
Once the sessions are complete, there is still important work to do — from reviewing the draft report and coordinating comments, to assigning action owners, tracking progress, and supporting close-out. In many cases, this post-study phase can take longer than the workshop itself.
Understanding that from the outset helps you plan more realistically and avoid treating the workshop as the finish line. A HAZOP only creates value if the outputs are properly captured, reviewed, and followed through.
How to Plan and Prepare for the HAZOP Study
Planning sets the foundation for a successful HAZOP. Thorough preparation ensures the right people are involved, the right information is available, and the study can run efficiently from day one. Good planning also makes your role as Project Manager much smoother, giving you confidence that the workshop and follow-up activities will be effective.
Here are five practical tips to guide your preparation and planning.
1. Familiarise yourself with the HAZOP process
To manage a HAZOP effectively, you need a solid understanding of how the process works.
Review corporate procedures, templates, and examples of previous HAZOP studies to familiarise yourself with how things are typically done in your organisation. Understanding the flow of the study will help you anticipate requirements, identify potential bottlenecks, and communicate effectively with both the facilitator and participants.
If you are new to the process, AI tools can also be a useful way to familiarise yourself with HAZOP terminology, typical study structure, and the roles involved — provided you use them to build understanding, not to replace your organisation’s procedures or technical expertise.
Being familiar with the process also helps you understand what inputs are needed, what outputs to expect, and when decisions or approvals may be required. This background knowledge allows you to support the facilitator and the wider HAZOP team more effectively.
2. Assemble the right team
The success of a HAZOP depends heavily on having the right people in the room.
Work with the design lead to select participants with the necessary discipline expertise, as well as the facilitator and scribe. Ensure that all critical functions are represented and that participants will be available when needed.
Early engagement of the right people helps avoid last-minute scheduling conflicts and ensures that discussions are productive. A well-prepared team is the key to identifying hazards thoroughly and generating actionable recommendations.
3. Define the study scope early
A clear and agreed-upon scope is essential for an effective HAZOP.
Work with the facilitator and design lead to draft a Terms of Reference that outlines what will be reviewed, which systems or nodes are included, and any exclusions or assumptions.
Sharing and agreeing on the scope with participants before the study begins sets expectations, prevents misunderstandings, and ensures the workshop stays focused on the most important areas. It also makes follow-up and reporting much more straightforward.
4. Ensure key resources are available
A HAZOP cannot run effectively without the right information and tools.
Confirm that all necessary documents — such as P&IDs, process descriptions, operating procedures, and control philosophies — are current and accessible. Check that any required software, templates, or tools are available and functional.
Having everything prepared in advance reduces delays during the study, avoids unnecessary interruptions, and keeps the facilitator and participants focused on the analysis.
5. Plan logistics carefully
Whether the study is virtual or in-person, smooth logistics are crucial.
Confirm session schedules, room bookings, IT setup, and participant readiness. If virtual, ensure all attendees have access to systems, software, and any online collaboration tools needed.
Proper logistical planning minimizes distractions and keeps the workshop running on schedule. A seamless setup allows participants to focus on the HAZOP itself, rather than struggling with technical or organizational issues.
What to Do During the HAZOP Study
Once the HAZOP workshop begins, your focus shifts from planning to coordination. Your role is to make sure the study runs smoothly, stays on track, and has the support it needs to be effective.
That means staying close enough to the process to spot issues early, while giving the facilitator and technical team the space to focus on the analysis itself.
Here are five practical tips to help you manage the workshop effectively.
1. Be present at key points
You do not need to be involved in every technical discussion, but it is important to stay visible and engaged throughout the workshop.
A good approach is to be present at the start and end of each session so you can understand what has been covered, check progress against the plan, and identify any issues or gaps before the next session begins. This also helps you stay aware of anything that may affect logistics, attendance, or workshop timing.
Being present at key points allows you to maintain oversight without disrupting the flow of the study.
2. Protect the facilitator’s focus
The facilitator’s job is to lead the technical discussion, manage the pace of the study, and make sure the team works through the scope effectively. Your job is to help create the conditions for them to do that well.
That means stepping in to resolve anything that could distract them from the workshop itself — whether that is interruptions, missing attendees, access to documents, scheduling issues, or conflicting demands on participants’ time.
The more effectively you can remove those distractions, the easier it is for the facilitator to keep the workshop focused, productive, and on track.
3. Manage logistics in real time
Even with good preparation, issues can still arise once the workshop is underway. Rooms may not be available, IT may fail, key documents may be inaccessible, or schedules may need to shift at short notice.
As Project Manager, part of your role is to deal with these issues quickly and calmly so they do not interrupt the flow of the study more than necessary. This is especially important for virtual or hybrid workshops, where software access, screen sharing, connectivity, and file availability can have a direct impact on how efficiently the sessions run.
Staying on top of logistics in real time helps keep the workshop moving and reduces avoidable disruption for the team.
4. Maintain team continuity and engagement
A HAZOP relies on having the right people involved at the right time.
If key disciplines are absent, distracted, or dropping in and out of sessions, the quality and continuity of the study can suffer. Keep an eye on attendance throughout the workshop and make sure participants know when they are expected to be involved. If key individuals are unavailable or engagement starts to dip, address it early rather than waiting for it to become a bigger issue.
A team that is present, prepared, and engaged is much more likely to contribute effectively and maintain the quality of the review.
5. Check in regularly with the facilitator and team
Short check-ins during the workshop can be extremely valuable. They do not need to be formal or time-consuming, but they do help you stay aware of how the study is progressing and whether any adjustments are needed.
Use these touchpoints to understand whether the workshop is moving at the right pace, whether the scope is being covered as planned, and whether there are any concerns around participation, fatigue, logistics, or follow-up needs.
These conversations also help you spot problems early and make practical adjustments without interrupting the wider flow of the workshop.
What to do after the HAZOP study
The workshop itself is only one part of the HAZOP process. The real value comes afterwards — when findings are reviewed, actions are assigned, recommendations are implemented, and the outcomes of the study are properly followed through.
This phase is often less visible than the workshop, but it is no less important. In many cases, post-study management can take longer than the study itself, especially where multiple actions, stakeholders, and approvals are involved. This is often the stage where the Project Manager’s role really comes into its own — maintaining momentum, keeping responsibilities clear, and ensuring the study continues to move forward long after the workshop has ended.
Here are five practical tips to help you manage the post-study phase effectively.
1. Ensure the HAZOP team reviews the issued report
Once the workshop is complete, one of the first priorities is for the HAZOP team to review the draft report and make sure it accurately reflects what was discussed.
You may not be the right person to validate the technical content yourself, but you can coordinate the review process to ensure the right people check it carefully. This includes confirming that discussions, assumptions, recommendations, and actions have been captured correctly, and that any missing context or misunderstandings are addressed before the report is finalised.
A well-reviewed report is essential. It not only provides the foundation for managing recommendations and actions but also serves as a formal record that can be referred to in the future as an authoritative source of information.
2. Assign action owners and approvers
A HAZOP only creates value if its actions are clearly understood and followed through to completion.
In industry, avoidable incidents have occurred when known risks were assigned but never acted on. Ensuring this step is handled effectively is therefore crucial to the success of the process.
Once the report is in a suitable state, work with the design lead and relevant stakeholders to assign owners and approvers to each recommendation, turning them into actionable items. It is essential that action owners and approvers understand:
What is being asked of them,
Why the action was raised,
What outcome is expected, and
When it needs to be completed.
Clarity at this stage helps prevent delays, confusion, and actions being passed around without progress.
3. Ensure key resources and systems are in place for action management
Effective management of HAZOP actions requires more than assigning responsibility — the right people must have the tools and systems they need to complete actions, demonstrate completion, and maintain a clear record.
Success depends on having appropriate systems and resources in place to support both the HAZOP team and the wider organization. This is one area where effective software, can make a significant difference by providing automated action tracking, clear visibility and accountability, and a more efficient use of time with reduced effort for the HAZOP team.
Confirm that any action tracking software, templates, registers, or document control systems are fit for purpose and accessible to those who need them. Ensure supporting documentation is available where required, and that stakeholders understand how actions will be tracked, updated, and closed out.
A clear, usable system helps maintain momentum after the workshop and ensures that recommendations are followed through efficiently.
4. Track timelines and progress
Once actions have been assigned, your role shifts into maintaining visibility and momentum.
Monitor deadlines, dependencies, review points, and completion dates so that progress does not stall once people return to their day-to-day responsibilities. Regular follow-up is often needed to keep actions moving, especially when they involve multiple disciplines or approvals.
Using the right systems or software can make follow-up more efficient by automating reminders, tracking progress, and providing clear visibility for the Project Manager and all members of the team. However, these tools are most effective when supported by structured processes, consistent oversight, and proactive engagement to ensure the study continues to progress smoothly.
5. Be on hand to manage challenges
Even when actions are clearly assigned, challenges can still arise during close-out. People may change roles, priorities may shift, approvals may be delayed, or the original action owner may no longer be in the business or the right person to take something forward.
Part of your role is to help manage those issues when they arise — whether that means clarifying expectations, helping reassign ownership, escalating delays, or reconnecting the right people to keep things moving.
This kind of coordination can make a significant difference to whether HAZOP actions are completed effectively or gradually lose momentum over time.
Closing
The true value of a HAZOP is realised through careful planning, effective coordination, and diligent follow-through. While the workshop itself is often the most visible part of the process, the work before and after the sessions is what ensures meaningful outcomes and lasting impact.
A HAZOP Project Manager plays a central role in making this happen — connecting the right people, keeping the study on track, and ensuring recommendations are implemented effectively.
Here are the key takeaways from this guide to help you in your role as a HAZOP Project Manager:
Understand your role: You don’t need to be a technical expert, but you must know the HAZOP process, its stages, and what is required at each point.
Engage stakeholders early: Build strong relationships with the design lead, facilitator, and participants to ensure the right information, resources, and timing.
Plan thoroughly: Scope, team, documentation, and logistics must be prepared in advance to give the study the best chance of success.
Stay present and proactive during the workshop: Coordinate, monitor engagement, manage logistics, and support the facilitator to maintain momentum.
Follow through post-study: Assign clear action owners, ensure systems and processes are in place, track progress, and manage challenges to convert HAZOP findings into real-world improvements.
By focusing on these principles, HAZOP Project Managers — whether engineers, traditional Project Managers, or otherwise — can ensure the study delivers value, meets project objectives, and enhances process safety across the organisation.
