Major-accident prevention policy (MAPP)

Upper tier operators are required to draw up a document in writing setting out the major-accident prevention policy (MAPP) and to ensure that it is properly implemented.

The MAPP shall be designed to ensure a high level of protection of human health and the environment. It shall be proportionate to the major-accident hazards. It shall include the operator’s overall aims and principles of action, the role and responsibility of management, as well as the commitment towards continuously improving the control of major-accident hazards, and ensuring a high level of protection.

Lower tier operators the obligation to implement the MAPP may be fulfilled by other appropriate means, structures and management systems

Safety report

Upper tier operators are required to provide safety report for the purpose of:

  • demonstrating that a MAPP and a safety management system for implementing it have been put into effect
  • demonstrating that major-accident hazards and possible major-accident scenarios have been identified and that the necessary measures have been taken to prevent such accidents and to limit their consequences for human health and the environment;
  • demonstrating that adequate safety and reliability have been taken into account in the design, construction, operation and maintenance of any installation, storage facility, equipment and infrastructure connected with its operation which are linked to major-accident hazards inside the establishment;
  • demonstrating that internal emergency plans have been drawn up and supplying information to enable the external emergency plan to be drawn up;
  • providing sufficient information to the competent authority to enable decisions to be made regarding the siting of new activities or developments around existing establishments.
