Ineris’s approach progresses through following steps:
Establishment of the event chronology: nature of the involved materials and processes, sequence, circumstances of the accident and its effects (thermal, overpressure, toxic).
Determination of the most likely scenarios: formulation of hypotheses, when necessary by using testing means (e.g.: calorimetrical trials, reproduction of small- or mid-scale phenomena), graphic representations (cause tree) or modelling (effects of dangerous phenomena, damages to structure).
Evaluation of human and technical safety barriers: identification of safety devices, procedures, activities or tasks and evaluation of their performance (independence, response times, individual and collective behaviour, etc.).
Human and organisational analysis: taking into account prescribed and formal procedures, safety management systems (SMS), etc. and informal dimensions (discrepancies with procedures, representations, cultural dimensions, leadership, etc.).
Formulation of recommendations: technical, human and organisational aspects, prioritization of actions, recommendations for the short, mid, and long term.
Ineris also guides you in the implementation of these recommendations.
