• Mature and well-used
• Basis for almost all safety-related QRA
• Disaggregates risk into >100 hazardous events and ~3,000 precursors
• Risk Profiling Tool allows localisation

Champion cross industry initiatives
Identify safety priorities and share
with industry
Advise RSSB on its products, services

Collaboration bowties
▪ Inform a common cross-industry understanding of risk and how this risk is controlled
▪Highlight weak risk controls and identify what improvements can be made
▪ Identify where additional monitoring could improve understanding of the effectiveness of risk controls
▪Be overlaid with the various industry requirements and thus showing a clear link to industry standards
▪ Inform the future development of standards, guidance, tools and training.

What do collaboration bow ties look like?
▪High level – specified level of interface between DHs
▪Validated by cross-industry group
▪Barriers scored for effectiveness
– Publicly available (un-scored)
– Available to members (scored)
▪Chained where appropriate
▪Threat lines linked to SRM (where possible)

Effective monitoring allows the risk groups to understand:• The overall level of risk and temporal trends
in risk• The effectiveness of individual or groups of
controls• The effectiveness of any risk improvements

Monitoring residual risk – Safety Performance Indicators (SPIs)
• Measurements that reflect the effectiveness of the risk control arrangements.
• Used to determine whether (or not) any trends are appearing in safety performance.
• Two key types of SPI:

Using bowties to prioritise improvements: Scoring process
▪ Identify controls where control effectiveness could be improved
▪ Identify prospects or initiatives that are required to realise this improvement
– Improvement of existing control
– Implementation of new control

▪By how much would this project/initiative, in isolation, reduce this specific threat?
– Either directly
– As an enabler to further work

Using bowties to prioritise improvements: Prioritisation
▪Threat lines can be linked to SRM
– Robust estimate of the significance of the threat line (FWI/yr)
▪Controls may exist on more than one threat line
– Need to be combine safety benefits
▪Projects/initiatives can be plotted:
– Safety benefit score
vs
– Effort score

Generic hazards
Intended to be an input to risk assessment / hazard identification process
– Encourages a consistent approach to hazard naming and levels
– Reduces effort in hazard identification
– Reduces the likelihood of missing hazards
– Published for rolling stock in GEGN8642 issue 1

Development of generic hazards
• Start with an initial set of hazards
• e.g. the list in GEGN8642 issue 1
• As standards NTRs/RISs are updated, undertaking a mapping exercise
• Mapping each requirement to one or more generic hazards based on which hazards the requirement is potentially a control for
• If hazard doesn’t exist then create it
• Publish mapping as appendix to NTR/RIS
• If the mapping is successful (and useful to the users) then complete for all standards
• As bowties are developed “causally” ensure that there is consistency between generic hazards and bowtie top events and threats
