HAZID/HAZOP Consultancy
Arthian’s consultants deliver HAZID and HAZOP studies to identify hazards, assess risks, and strengthen process safety. Practical, audit‑ready support tailored to complex operations.
Arthian delivers HAZID (Hazard Identification) and HAZOP (Hazard and Operability) studies to support the assessment and development of a safe and complaint design across high-hazard sector. These structured assessments help identify potential risks, operability issues and major accident hazards, ensuring compliance with COMAH, DSEAR and functional safety frameworks.
We support:
- Distilleries and drinks manufacturing
- Chemical and pharmaceutical facilities
- Energy from waste and renewables
- Industrial gases, fuels and storage
- High-risk manufacturing and processing sit
What are HAZID and HAZOP Studies?
A HAZID is a high-level, early-stage risk assessment that identifies potential hazards across systems, processes and site layouts. It’s typically used:
- During concept or FEED stages
- For new developments or major modifications
- For ‘non process’ facilities such as warehousing and logistics
- To screen for Major Accident Hazards (MAHs)
- As part of COMAH safety report preparation
A HAZOP is a detailed, node-based assessment that evaluates how process deviations could lead to safety or operability issues. It’s used to:
- Analyse process lines, vessels and control systems
- Identify causes and consequences of deviations
- Recommend safeguards and actions
- Support LOPA, SIL and functional safety analysis
The Road to HAZID & HAZOP
A successful HAZID or HAZOP starts long before the workshop takes place.
Whether you’re developing a new facility, modifying an existing process, introducing new equipment or expanding production capacity, the quality of a safety study depends on the quality of the information available.
Many projects require engineering development before a HAZID or HAZOP can provide meaningful value. Our team supports every stage of the journey, helping clients develop the technical information needed to identify hazards, assess risks and make informed decisions.
By combining process engineering and process safety expertise within one team, we can support projects from initial concept through to implementation, ensuring studies are undertaken at the right time and with the right information.

We lead workshops that define hazard sources, assess risk pathways and recommend mitigation strategies, often forming the foundation for later HAZOP or LOPA studies.

Our HAZID and HAZOP Services
We provide expert scribing and documentation services to ensure process safety studies are captured clearly, consistently, and in line with regulatory expectations. Our approach ensures your safety assessments are well-documented, defensible, and ready for review by regulators and stakeholders.
Our services include:
- Professional scribing for HAZID and HAZOP workshops
- Structured documentation of safety study outputs across disciplines
- Support for auditability and regulatory compliance under industry standards
- Clear records that enhance traceability and risk management
We leverage trusted, industry-recognised tools to ensure consistency, traceability, and quality in process safety documentation. By using proven platforms, we help teams streamline safety studies and enhance decision-making across complex projects.
Our capabilities include:
- Use of PHA Pro for structured hazard identification and risk assessment
- Application of Bowtie XP to visualise risk pathways and control measures
- Delivery of high-quality outputs that support auditability and regulatory compliance
- Integration of software outputs into broader safety and risk management frameworks
We ensure safety study outputs are fully aligned with wider regulatory frameworks, supporting compliance and operational integrity. Our holistic approach ensures your safety documentation is consistent, defensible, and ready for regulatory scrutiny.
Our services include:
- Seamless integration of HAZID, HAZOP and risk analysis outputs into COMAH safety reports
- Alignment with DSEAR requirements for hazardous substances and explosive atmospheres
- Support for OBRA (Occupied Building Risk Assessment) to protect personnel and assets
- Incorporation of findings into SIL (Safety Integrity Level) assessments for functional safety
We help clients move from safety study outputs to meaningful implementation by prioritising actions and managing risk effectively.
Our services include:
- Tracking post-study actions to ensure accountability and follow-through
- Assigning risk rankings to support informed decision-making
- Helping clients prioritise mitigation measures based on impact and feasibility
- Providing structured outputs to support regulatory compliance and internal governance
Our services are available nationwide, with flexible delivery options to suit client needs—whether remote participation or on-site support is required.
Frequently Asked Questions
What’s the difference between HAZID and HAZOP?
HAZID is a high-level screening of potential hazards across systems and layouts. HAZOP is a more detailed study that examines how process deviations might lead to safety or operability issues.
When is a HAZOP typically required?
It’s most commonly carried out during detailed design or pre-commissioning stages, but can also support Management of Change and major modifications.
Do you facilitate the studies and provide documentation?
Yes—we lead workshops, document outcomes, and support clients with action tracking and study reports ready for internal use or regulatory submission.
Can HAZOP findings support other safety assessments?
Absolutely. HAZOP outputs often inform risk ranking, mitigation plans, and are used in preparing COMAH safety reports or other regulatory deliverables.
