London Branch – Innocent Bystanders? Taking human activities into account in QRA
The methods in common use for quantitative risk assessment in the oil and gas industries model consequences of hazardous releases in detail, but do not address causes. In particular, they treat workers as innocent bystanders, ignoring their influence on hazard scenarios. As a result, QRAs cannot fully meet their objectives. In particular:
- Since they ignore causes of releases, they do not help identify or evaluate prevention measures, but only consequence mitigation;
- Treating Location Specific Individual Risk (LSIR) as independent of personnel distribution underestimates risk to people engaged in activities such as maintenance that tend to cause releases.
This webinar will explore how risk predictions can be refined without making QRA models unduly complex, and how the resulting information can be used to guide other methods such as HAZOP and Bowtie towards the most significant causes of release and methods to mitigate them.
The webinar will be presented by David Stephens. David is a Certified Risk Professional with thirty years’ experience in safety assessment and management in the nuclear and oil and gas industries. He offers consultancy and freelance services covering major accident hazards management throughout the engineering process. David’s particular focus and expertise include:
– management of specialist safety studies and integration into engineering design;
– joined-up hazard management, from hazard identification to safety case and operational and maintenance requirements.
