Improving Process Safety in Food Manufacturing: A Case Study on Plant Upgrade Risk Assessment

Improving Process Safety in Food Manufacturing: A Case Study on Plant Upgrade Risk Assessment

A leading global food manufacturer commissioned Finch to support the safety assessment of a brand new expansion Plant Upgrade at one of its UK production facilities.

Project Summary

The project was in its detailed design phase, and the client sought to ensure that the upgraded system met rigorous safety standards before installation.

Challenge

The client had recently completed a Hazard and Operability (HAZOP) study that identified 19 hazardous scenarios with high residual risk. These scenarios posed potential threats to personnel safety, including exposure to hazardous chemicals, equipment failure, and process deviations. The client needed a deeper analysis to determine whether additional safety measures, particularly Safety Instrumented Functions (SIFs), were required to reduce risks to acceptable levels.

Our Approach

Finch Consulting facilitated a Layer of Protection Analysis (LOPA) workshop across two sessions, involving a multidisciplinary team from the client’s engineering, operations, and safety departments. The sessions were conducted remotely via Microsoft Teams, ensuring accessibility and collaboration across locations.

Our consultants:

  • Reviewed the HAZOP findings and selected scenarios for LOPA assessment.
  • Applied industry standards (IEC 61508 and IEC 61511) to guide the methodology.
  • Evaluated initiating event frequencies, independent protection layers (IPLs), and conditional modifiers.
  • Calculated required Safety Integrity Levels (SILs) for each scenario.
  • Documented all findings in a structured LOPA worksheet for transparency and traceability.

Key Outcomes

- No additional SIFs were required for the scenarios assessed, indicating that the existing safeguards were sufficient.
- 13 general recommendations were made to enhance operational safety and commissioning procedures.

These recommendations were handed over to the client for implementation prior to commissioning.

Impact

By partnering with Finch Consulting, the client gained:

  • Confidence in the safety integrity of their upgraded plant design.
  • A clear roadmap for procedural and design improvements.
  • Assurance that personnel safety risks were thoroughly assessed and mitigated
