Human Factors and Ergonomics

Human error has long been identified as a contributing factor to incident causation. Commonly cited statistics claim human error is responsible for anywhere between 70-100% of incidents.

Achieving and maintaining reliable human performance is consequently a major concern in organisations that rely on barrier management.  Major hazard organisations consequently wish to know:

  • That the human performance they need and expect can reasonably be relied on to be delivered when and where it is needed.
  • The controls they intend to have in place are as robust as they reasonably can be against the loss of expected standards of human reliability.
  • Ensure that barriers credited with performing a role in managing Major Accident Hazard (MAH) risk, are not degraded through a loss of human reliability.

Xodus and Human Factors Engineering

Xodus offers a range of Human Factors services for ensuring HF is considered within engineering phases of new developments/ modifications and ensuring that HF issues are adequately managed in operational installations.

The Xodus HF department is fully integrated into the well-established Technical Safety and Risk (TSR) team giving us access to a wide range of expertise in addition to discipline specialists.  We pride ourselves on having a pragmatic approach to HF and our ability to integrate our analyses into the overall MAH management process.

Services include, but are not limited to:

  • Development of HF/E philosophies, plans, method statements etc.
  • Safety Critical Task Analysis (SCTA).
  • Human Factors integration into Barrier Management/ Bowtie models. 
  • Human Factors Screening Assessments. 
  • Specialist HF input into safety cases and material changes.
  • Specialist attendance in safety studies e.g. HAZOP, HAZID, LOPA, Layout Reviews.
  • Secondment of HF specialists into major project design teams.
  • Execution of HF engineering studies in line with OGP 454 and other recommended practices. 
  • Human reliability assessments and ALARP demonstrations.
