Natech accidents: an analysis of sites other than Fukushima with the Tokohu seism and tsunami in March 2011

We are appreciative of the work performed in French by BARPI (Bureau d’Analyse des Risques et Pollutions Industriels) of the French ministry of sustainable development on natech accidents stemming from the Tokohu seism and the ensuing tsunami that occurred in March 2011. This is an input to the accident database Aria (Analyse, Recherche et Information sur les Accidents). This analysis covers accidents at sites in multiple industries  on top of defining natech accidents as technological accidents caused by a natural event.

Natech accidentsThe analysis provides aggregate data on products most often involved in accidents stemming from a seism or from submersion by water. A detailed description of tsunami is made. This panorama covers :

  • manufacturing sites
    • automotive assembly
    • cement
    • chemicals production
    • electronics
    • food processing
    • glass making
    • metal work
    • oil refinery
    • steel making
    • wood transformation
  • logistics sites
    • airports
    • harbors
    • warehouses
  • utilities sites
    • power plants
    • water treatment
  • hydraulic works of engineering
    • dams
    • embankments.

The portion devoted to lessons learned with regards to seismic, natech and water submersion risks is one of few elements of information for these low probabilitry but high severity hazards. Individuals responsible for health and safety who care for best available techniques should factor this analysis in their sources of information on hazards.

Systems thinking : how to see circles of influence rather than straignt lines

What is it?

Systems Thinking is a discipline for seeing the underlying structure of a system and understanding its dynamic complexities. This discipline has its own language based on three building blocks:

  • Reinforcing feedback: when a small change builds on itself
  • Balancing feedback: when a system is seeking status quo on a certain goal
  • Delays: when things happen eventually

The building blocks are meant to help us see the reality systematically: see circles of influence rather than straight lines; as well as discerning high from low leverage changes.

Systems Thinking within PDCAply

Using a systematic way of thinking enables us to assess and understand client contexts in their human, organisational and technical dimensions. Only after identifying the main circles of influence specific to a client and his environment can we do our best at providing an adequate and relevant solution.

Regulatory compliance and voluntary measures often entail change in business practices. Our consulting services use Systems Thinking to manage change of the management system (PDCAtune) and of the information system (PDCAdapt).
