Legal basis

Section 15 of the Major Accident Ordinance (12th BImSchV)

Section 7 of the Major Accident Ordinance (12th BImSchV)

Service description

The competent authority is obliged to inform the operators of operating areas in accordance with the Major Accident Ordinance as to which operating areas or groups of operating areas may have an increased probability of major accidents due to their geographical location, their distance from one another and the hazardous substances present in their facilities, or in which these major accidents may have more serious consequences (domino effect).
For the assessment, the authority requires from you in particular

  • Information provided in the notification and the safety report,
  • Information provided by the operator following a request from the competent authority for additional information and
  • Information obtained by the competent authority through monitoring measures.

As an operator, you also provide information about your immediate surroundings and the operating area. These include, for example, details

  • to neighbouring operating areas,
  • to other establishments that are not covered by the Major Accident Ordinance, and
  • on areas and developments,
    • from which an incident could occur or
    • where the probability of an incident occurring may increase or the impact of an incident and domino effects

can worsen.
If the authority has additional information, it must make it available to you as the operator immediately, provided this is necessary for the cooperation between the operators.

If a domino effect has been identified in operational areas, the potential hazards must be taken into account in the safety report, the accident prevention plan, the safety management system and the internal alarm and hazard prevention plans.
