Summary:
            The paper illustrates an interdisciplinary contribution (ergonomics, psychology, work psychology, 
economics,  public  management  and  policy)  to  the  prevention  of  the  risk  of  power  outage.  This  
exploratory project, still ongoing at the time of submission, aims at analysing the perceptions of this risk 
among a set of actors representing public institutions, electricity production and distribution companies, 
and  citizens.  By  immersing  themselves  in  a  probable  blackout  scenario  during  an  individual  interview,  
these people were led to verbalise their experiences and knowledge, as well as the role they would play 
and the behaviours they would adopt, if this scenario were to materialise. A content analysis revealed 
recurring  aspects  common  to  several  actors,  but  also  specificities  linked  to  their  activity.  The  results  
underline the need to develop exchanges and coordination between these actors, so as to develop a 
common  operational  reference  framework  for  the  various  institutions  involved  in  the  prevention  and  
management of a power outage.
