Our service
With a wealth of experience working with COMAH sites, we can help you demonstrate full compliance with regulations. We have helped organisations responsible for critical infrastructure through to boutique distilleries to ensure their COMAH capability and compliance exceeds the COMAH Regulations guidelines. We have had numerous successes in lifting legal actions imposed on COMAH establishments. In fact, we have never in our company's history failed to adequately address regulatory expectations either in advance of an inspection or when being brought in to address actions raised post inspection.
Our Approach
Phase 1 - Orientation
High-level discussion and orientation of the task. We rely on operator and engineer engagement as well as
time on site to physically see the task in action or enacted by way of a “walk and talk” or “touch drills”.
Phase 2 - Documentation
We analyse all relevant documents, e.g. HAZOP, LOPA,
procedures, WCCs and ICCs, and use our proprietary software TASC© to produce a draft of the Task Analysis.
Phase 3 - Workshop
Once we have drafted the TA - based on the documentation provided - we will hold a
workshop with the operators who do the task. It is our strong preference that this is done on site and will
include a task walkthrough to present the “work as done” not “work as imagined”
Phase 4 - Human Error Analysis
With the TA constructed, a site walk-through is completed and the work, as done, is validated, we are ready
to run into the HEA. The HEA will be chaired by IHF and should be properly attended by nominated individuals from the Engineering fraternity.
Phase 5 - Reporting & Outputs
Finally, we would align the output from the HEA (above)
with the LOPA and Fault Tree Analysis (FTA) to report on the Human Error Probability (HEP). The outputs are added to the LOPA and FTA to ensure the overall reliability calculation is accurate.
Previous clients
Interconnector (Owned by Fluxys & Snam)
Interconnector controls the UK – Belgium Methane-transfer pipeline. IHF was engaged to conduct HAZID studies, safety-critical task analysis and provide general human factors advice.
United Molasses Storage (UMS)
At the recommendation of the HSE, UMS approached IHF with an urgent need to review and re-design their Management of Change procedures and documentation for their Hull and Liverpool Bulk Liquid Storage facilities. This procedure is now in place across all UMS sites in the UK.
Tenants Distribution
IHF reviewed and updated two Safety Critical Procedures from an HEA and HRA perspective for Tennants Distribution. This was conducted using our systematic method that includes the COMAH delivery guide and SRAM, IHF experience/expertise and very recent guidance provided to us by the regulator.
