According to the German Water Directive (WHG), containers for water-hazardous liquids must have overfill prevention systems. These systems monitor the level and trigger an alarm before the permitted level is reached. The WHG is thus one of the most important laws for environmental protection and to ensure operational safety. The application of, and compliance with, this law is monitored by organizations such as the Technical Inspection Authority TÜV.
