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.

SEVEZO Study is an essential tool regarding Major Industrial Accidents and the assessment of their effects in population, facilities and environment.

European Directive SEVEZO III is applied in Greece through K.Y.A. 172058/2016 concerning “Establishment of rules, measures and conditions for risk prevention from major industrial accidents in industries or facilities due to the presence of dangerous substances, in compliance with regulations of 2012/18/EU”.

Industrial facilities under the Directive SEVEZO III are obligated to conduct and send to corresponding Authorities the Safety Study or its notification, depending of the existing quantities of dangerous substances.

The study includes data regarding the facility, quantities of stored materials and the assessment of the possibility of Major Industrial Accident occurrence, considering the facility’s location along with the neighbouring facilities that are more or less dangerous and the possibility of a chain – reaction event “Domino” 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

Each corporation that has in its facilities dangerous substances in the form of raw material, product, by-product, residue or intermediate product, including ones expected to occur in case of accident, in quantities equal or exceeding critical points mention in legislation, is obligated to send to corresponding authorities the Major Accident Prevention Policy and Safety Study.


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 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.

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.

Biosafety undertakes the conduction of Safety Studies and the Notification Files according to SEVEZO III Directive as well as the composition-organization of Scientific HAZOP Study Teams, abiding by rules and regulations of legislation, the specifications of each facility and the international regulations and standards.
