The ICPDR developed a method for assessing potential danger from environmentally relevant industrial plants. On the basis of the WRI (water risk index) it is possible to establish the accidental risk spots (ARS). However, the problem is that this WRI takes into consideration only the volumes of substances and the degrees of water risk from the substances, but not the types of safety level. Thus a company in which all recommendations of the river basin commissions are realized, is evaluated exactly the same as a company with serious safety-relevant faults. That requires an evaluation of a plant with regard to the current risk. The current risk can only be determined and assessed on the basis of a thorough testing and evaluation of the relevant plant. The Checklist Method that has been developed is particularly suitable for this purpose. The most complex industrial plant can be checked and evaluated simply, in structured form, and in accordance with international recommendations by means of this method. Based on this method a possibility was developed that characterizes the safety level of a plant.
