HAZOP
& HAZID

HAZOP (Hazard and Operability) studies are structured, systematic examinations of process deviations using specific guidewords, typically conducted on detailed designs.

HAZID (Hazard Identification) studies follow a similar format but use different guidewords (like fire, explosion, toxics release) and are often conducted earlier in the project lifecycle, prior to detailed design, to identify major hazards that might affect the process.

HAZID studies are typically conducted prior to the start of detailed design, often as input to risk assessments required for regulatory approvals. HAZOP studies are usually conducted when the detailed design is available, to identify specific operational issues and hazards that could arise from process deviations.

Both studies require a multidisciplinary team including process engineers, operations staff, and safety professionals. The specific team composition may vary depending on the process being reviewed, but should include those with detailed knowledge of the design and operation of the system being studied.

Our leaders are highly experienced and widely recognised in the industry. They are frequently approved as HAZOP study leaders for major developments by regulatory authorities such as the NSW Department of Planning. Many are accredited as Senior HAZOP Study leaders (the highest level) as per Orica's internal requirements.

Planager consultants lead many different types of HAZOP study techniques including: Process HAZOP Study (for both continuous and batch operations), Materials Handling HAZOP Study, Procedures HAZOP Study, Metal Handling HAZOP Study, Building HAZOP Study, Ship-to-Shore HAZOP Study, Machinery HAZOP Study, and Transport HAZOP.

The duration depends on the complexity of the process or system being reviewed. A simple HAZID might take 1-2 days, while a comprehensive HAZOP for a complex process could take several weeks. We can provide a more specific estimate after understanding the scope of your project.

Typical deliverables include a comprehensive report documenting the study methodology, team composition, nodes/sections reviewed, hazards identified, risk rankings, recommendations, and action items. We can customise the format to meet your specific requirements.

Yes, Planager is an accredited provider of Orica's HAZOP training courses. We offer Basic HAZOP (2 days), HAZOP Leader (2 days), Combined Basic and HAZOP Leader Course (3 days), and HAZOP Awareness (1-day) training. Our public course schedule is available on our website.

We have extensive experience across multiple industries including chemical and petrochemical, energy sector, oil and gas, mining and minerals processing, manufacturing, food and beverage, pharmaceutical, and water sector. Our recent projects page provides examples of our work across these sectors.

These studies are often key components of regulatory requirements, particularly for major hazard facilities, dangerous goods sites, and other high-risk operations. They demonstrate due diligence in identifying and managing process safety risks and are frequently required by authorities such as the NSW Department of Planning.

Yes, we can tailor our approach to suit your specific process, industry requirements, and organisational culture. Our extensive experience across different industries allows us to adapt the methodology while maintaining the technical rigour required for an effective study.

We can provide ongoing support including action item tracking, revalidation studies, implementation support for recommendations, integration with your management of change processes, and training to build internal capability. We aim to develop long-term partnerships with our clients to support continuous improvement in process safety.
