Everything you need to know about mandatory inspections of storage tanks
Storage tanks play a crucial role in the safe containment of liquids such as oil, chemicals, and waste. Regular inspections are not only legally required under the VLAREM II regulation (Flemish Regulation on Environmental Permits), but also essential for preventing leaks and environmental damage. In this article, you’ll find everything you need to know about storage tank inspections—regardless of type or application.

Prevent leaks and contamination
Guarantee the safe storage and use of hazardous substances
