Process Safety Analysis (HAZOP)

6 weeks · 0 milestones

Conduct a Hazard and Operability (HAZOP) analysis for a real or representative process section, applying the HAZOP methodology systematically to identify potential deviations, their causes, consequences, and safeguards. The analysis must cover: at least 2 process nodes (defined sections of the P&ID) with all relevant guide words applied to each parameter (flow, temperature, pressure, composition, level), a completed HAZOP worksheet for each node (deviation, cause, consequence, severity/likelihood rating, existing safeguards, and recommendations), identification of at least 3 significant hazard scenarios with unacceptable risk that require additional safeguards, and a safeguard recommendation table. The analysis must be based on a real or realistic P&ID — not a hypothetical system described in prose. Preferred proof: a HAZOP study conducted as part of a real project safety review. Accessible alternative: HAZOP of a publicly documented process (many published process engineering case studies include simplified P&IDs suitable for HAZOP exercises; IChemE publishes free guidance with example systems). The HAZOP methodology is fully documented in free HSE and CCPS guidance documents — no software license required. Proof artifacts: the HAZOP worksheet (analysis artifact) and the safeguard recommendation table (documentation artifact). Verification: a process safety engineer challenges the consequence assessment for the most severe scenario identified — 'you assessed this as a toxic release to atmosphere; have you considered the domino effect on adjacent equipment?' — requiring you to reason through your own hazard scenario.
