At IHF we have a wealth of experience working with COMAH sites, in particular helping COMAH sites demonstrate compliance with the new regulations. We have helped organisations responsible for critical infrastructure through to boutique distilleries to ensure their COMAH capability and compliance exceeds the COMAH Regulations 2015 guidelines.
We have had numerous successes in lifting Actions Legal imposed on COMAH establishments and upstream oil and gas companies. In fact, we have never in our 7 year history failed to adequately address regulatory expectations either in advance of an inspection or addressing issues after an inspection.


Some examples of our success include:
Interconnector: Interconnector controls the UK – Belgium Methane-transfer pipeline. IHF have been 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.
Tennants 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.


IHF designs, develops and delivers highly experiential and interactive training for organisations of all sizes within the Oil & Gas sector. These courses include:

  • e-Learning
  • Major Accident Hazard awareness (MAH)
  • Human Factors Awareness (HFAT)
  • Safe Working Behaviours/Behavioural Based Safety (SWB/BBS)
  • Train the Trainer

Document Design & Use

IHF is highly skilled at Gap Analysis, development and production, and re-design and reformatting of documents in isolation or as part of a wider HF intervention.


IHF are industry experts on Fatigue Risk Management (FRM) – audit, re-design, implementation and review.

Workload & Staffing Levels

Task Analysis and Time Line Analysis, and measuring the impact of Performance Influencing Factors (PIFs) are some of the techniques IHF have used to improve safety and business performance as a result of improving inefficient workload and staffing levels.


IHF can conduct evaluation of communication, decision-making, awareness, workload and Team Performance Analysis within the framework of the SHELL model.
