LOPA (Layer of Protection Analysis)

Assessing whether safeguards are sufficient through LOPA (Layer of Protection Analysis)

LOPA (Layer of Protection Analysis) provides a structured, semi quantitative method for evaluating whether existing protection layers reduce risk to a tolerable level. It supports consistent and defensible risk based decisions.

When LOPA is used

  • Following HAZOP or PHA studies

  • Where safeguard adequacy is unclear

  • To support SIL determination

  • During risk based design decisions

What we deliver

  • Clear comparison of risk against tolerability criteria

  • Justification for additional safeguards where required

  • Transparent and auditable risk decisions

How LOPA links to other process safety services

LOPA (Layer of Protection Analysis) integrates closely with HAZOP, Functional Safety, consequence modelling and Process Safety Management decision making.

Frequently Asked Questions About Process Safety Consultancy

What is process safety consultancy and how does EHS International support it?

Process safety consultancy focuses on preventing major accident hazards such as fires, explosions, toxic releases and catastrophic equipment failures. At EHS International, our process safety consultants work with organisations to identify and control risks arising from hazardous substances, complex processes, ageing assets and human factors.

Our consultancy is practical and evidence based. We focus on real world application, ensuring process safety controls are effective, proportionate and integrated into day to day operations rather than existing only on paper.


How is process safety different from health and safety and how does EHS International address both?

Health and safety typically focuses on preventing personal injuries such as slips, trips, falls and manual handling incidents. Process safety addresses low frequency, high consequence events that can result in multiple fatalities, environmental harm and severe business disruption.

EHS International supports organisations to manage both disciplines effectively. Our process safety services complement occupational health and safety systems by strengthening governance, leadership oversight and control of major accident risks.


Which industries does EHS International support with process safety consultancy?

EHS International delivers process safety consultancy across a wide range of high risk and regulated sectors, including:

  • Chemical and pharmaceutical manufacturing

  • Energy, utilities and power generation

  • Oil, gas and petrochemical operations

  • Manufacturing and engineering environments

  • Food and beverage processing with hazardous substances

  • Warehousing, logistics and Dangerous Goods operations

Our consultants have hands on experience in complex industrial environments and tailor solutions to the specific hazards and regulatory obligations of each sector.


When should an organisation engage EHS International for process safety support?

Organisations typically engage EHS International when they are:

  • Designing new plant, processes or facilities

  • Modifying existing equipment, processes or layouts

  • Introducing new chemicals or raw materials

  • Preparing for regulatory inspections or audits

  • Responding to incidents, near misses or enforcement actions

  • Reviewing ageing infrastructure or legacy systems

Early engagement allows us to identify risks proactively and support safer decision making throughout the lifecycle of your operations.


What is a HAZOP study and how does EHS International deliver them?

A HAZOP study is a structured and systematic hazard identification technique used to assess potential deviations from intended process design and their consequences.

EHS International facilitates HAZOP studies using experienced, independent leaders who guide multidisciplinary teams through a clear and robust process. Our focus is on meaningful outcomes, ensuring actions are clearly defined, prioritised and aligned with operational reality.


How does EHS International support Process Safety Management (PSM)?

Process Safety Management is a structured framework used to manage major accident hazards throughout the life of a facility. EHS International supports organisations to design, implement and continuously improve PSM systems that are proportionate to their risk profile.

Our support includes gap analysis, system design, governance frameworks, documentation development, leadership engagement and workforce training. We focus on embedding PSM into everyday operations rather than treating it as a compliance exercise.


Does EHS International provide on site process safety consultancy?

Yes. EHS International provides on site, hybrid and remote process safety consultancy depending on the scope and nature of the work. On site support is often used for hazard studies, audits, inspections and practical assessments, while remote support can be effective for documentation review, system development and advisory work.

Our flexible delivery model allows us to support organisations efficiently without compromising quality or effectiveness.


Can EHS International support regulatory compliance in Ireland, the UK and internationally?

Yes. EHS International supports organisations in meeting Irish, UK and international process safety and Dangerous Goods regulatory requirements. Our consultants work closely with clients to interpret legislation, prepare for inspections and demonstrate compliance to regulators and stakeholders.

We also support organisations operating across multiple jurisdictions by aligning process safety systems with recognised international standards and best practice.


Does EHS International work with in house EHS and engineering teams?

Absolutely. EHS International works collaboratively with internal EHS, engineering, operations and leadership teams. Our role is to provide independent expertise, technical depth and objective challenge while strengthening internal capability.

Many clients engage us as a long term process safety partner to support continuous improvement, audits, training and strategic risk management.


Is EHS International suitable for smaller organisations?

Yes. Process safety risks are not limited to large organisations. EHS International works with organisations of all sizes, tailoring the scale and depth of consultancy to the complexity and hazard profile of the operation.

Our proportionate approach ensures smaller organisations receive practical, achievable solutions that deliver real risk reduction.


How long does a typical process safety project with EHS International take?

Project duration depends on scope, complexity and objectives. Some process safety reviews or gap analyses can be completed within days, while more complex projects such as full PSM implementation or major hazard studies may take several weeks or months.

EHS International provides clear scopes, deliverables and timelines at the outset to ensure transparency and certainty.


How do we start working with EHS International?

The first step is a confidential conversation with one of our process safety specialists. We take time to understand your processes, hazards, regulatory obligations and business objectives before recommending a practical and proportionate approach.
