When designing dikes for storage tanks, they are intended to contain how much extra volume of product?

When designing dikes for storage tanks, the additional volume they are intended to contain is typically 10% of the total volume of the stored product. This extra capacity accounts for potential overflow, leaks, or other unexpected releases, ensuring that any hazardous materials stay contained within the dike system and do not leak into the surrounding environment.

This practice aligns with safety regulations and guidelines to prevent environmental contamination and protect public health. The 10% additional volume is a balance that provides assurance without excessively increasing the size of the dike, which could lead to increased construction costs and potentially unnecessary material usage. Understanding this principle is crucial for compliance with safety standards in hazardous materials handling and management.
