Prevention and management of Major Industrial Accidents (MIA) has been addressed by Europe through Directives SEVEZO (I, II, III). SEVESO is a city locating in Italy where a Major Industrial Accident occurred in 1976 and thus the Directive was named after the city. 


European Directive SEVEZO III is applied in Greece through K.Y.A. 172058/2016.  


The study includes data regarding the facility, quantities of stored materials and the assessment of the possibility of Major Industrial Accident occurrence. 

Information included in the SEVEZO III Study is related to: 

  • The facility’s environment 
  • Production method and process 
  • Dangerous substances 
  • Risk of accidents and prevention measures 
  • The severity of the accident, its consequences to neighbouring areas – facilities and its extent 
  • Means of protection and intervention combating the incident



HAZOP Study (Hazard and Operability) is a detailed and analytical examination process of a complicated procedure or operation, existing or being-planned, in order to identify and evaluate thoroughly, risk causing issues that might affect facilities and personnel. 

HAZOP study is based on the principle of analyzing the overall complex process in a number of simpler sections called “knots” and are evaluated separately. HAZOP study is a team project. It requires the participation of engineers of various specialties and the implementation of specific methodology, for the technical-scientific part as well as the administrative part, i.e. meeting scheduling, communication, data transferring and documentation.
