As the operator of an upper-class operating area, you are obliged to provide the competent authority with the information necessary for the preparation of external alert and security plans. The aim of the transmission of information is to ensure effective security by interlinking internal and external alarm and security planning. Therefore, cooperation between operators and the authorities responsible for civil protection and general security should take place at the time of the preparation and updating of the internal alert and security plans.

Cooperation between operators and authorities is absolutely necessary for the definition of external hazard areas.

Once established and updated, the content of the internal alert and security plans shall be communicated to the authorities responsible for civil protection and general security to the extent necessary for those authorities to carry out their tasks. Cooperation should therefore discuss the details of which documents should be forwarded to the authorities with regard to their distribution of tasks.
