Julie Bell

Director and Human Factors Expert

Working for the Health and Safety Executive, I carried out research, policy, investigation, expert witness, and operational work in most Human Factors areas. I am recognised internationally for my work in Quantified Human Reliability Assessment and Fatigue Risk Management. I am the co-author of the updated and revised Human Error Assessment & Reduction Technique (HEART+). I have trained people in its use as well as helping organisations quantify human reliability as part of their risk assessment.  I contributed to the 2023 revision of the COMAH Competent Authority’s Human Factors Operational Delivery Guide, the standard against which HSE’s regulators inspect Human Factors on Major Hazard establishments.
