    Process Hazard Identification & Operability Analysis

    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 sites

    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

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

    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.
