Since 1987 – Safety Consultancy

Risk Evaluation and Mitigation

A safety review/report is developed to assess the residual risks coming from all the top-events highlighted in Top-events identification.

The goal of this activity is to weight the global risk level to record it as acceptable introducing, if needed, some improvements.

To reach this goal it is too simplistic to just plot together the different consequences: you will end up with a big envelope that will cover a huge part of your projected plant and that tells you quite nothing about residual risk. The right way to deal with this goal is to apply risk integration algorithms, the only approach that saves the principal aspects of every top-event:

  • likelihood
  • expected effects on people and equipments (different thresholds of “damage”)
  • corollary hypothesis (weather conditions, etc.)
  • variable exposure density (day or night shifts, turnaround, etc.)
  • variable resiliency (inside and outside the site based on hourly/day/year period)
  • etc.

Eidos has a huge experience on risk integration on industrial sites, seaport sites, wide area sites (Milan province, Lombardy region, Italian pipelines network, etc: from some km to thousands).


Contact Eidos to learn more about this new approach!

Of course Eidos can also implement the “usual methods” to evaluate residual risks like:

  • Standard and/or laws
  • Specific goal suggested/given by customer
  • ALARP
  • Risk matrix (3×3, 4×4 or 5×5)

Eidos is very proud of its engineering approach and background that let us speak the same language of the companies appointed to design the new plant. Eidos is able to assist companies in picking the best mitigation solution among:

  • Process improvements
  • Design improvements
  • Organisational reviews
  • Prevention and protection improvements

All the mitigations/improvements will be weighted quantitatively based on the chosen criteria above, reviewing frequencies, consequences, integration and exposure levels (you know we are engineers and love to evaluate through numbers!).

All the risk evaluations and mitigations will be displayed using CAD or GIS or Google Earth programs (see also Consequences analysis).
