Loss Prevention Then, and Now • Tremendous increase personal safety • Shift of focus towards prevention • Use of scientifically based methods • Support by academia • Educational courses bachelor level, Ph.D’s • 1990s Competition and ‘downsizing’ • Shift towards consultant and academic participation
The 1974 papers • “Safety is a money spinner” • Checklist • Prof. Trevor Kletz’s Myths of the Chem. Ind. • Vapor loud explosion research • Gas and dust explosion: • Dr. Bartknecht’s 1 m3 - vessel, KG and KStvalues. • Gas dispersion • Emergency response (in ‘industrial conurbation’)
Milestones: HAZOP - SMS - LOPA – STS1975 – 1990 – 1995 – 2000 System approach: System is more than the sum of parts Safety is emergent Nancy G. Leveson, 2011. Engineering a safer world, systems thinking applied to safety, The MIT Press
Conclusion • Evolution is from hindsight to foresight. • But, “loss prevention” calls for risk prediction. • There is an ‘Ocean’ of possibilities and uncertainty. • Hazard scenario identification needs improvement. • Digital P&ID + simulation + automation + thinking. • Enables risk assessment in design, layout, planning. • Digitization; Big Data & Analytics are on their way. • Indicators: holistically: plant, people, procedures. • Dynamic risk assessment operations. • Resilience assessment and preparation.
