Why is it essential to identify the spilled material when constructing a dike?

Identifying the spilled material is crucial when constructing a dike because it directly influences the selection of compatible diking materials. Different types of hazardous materials have varying physical and chemical properties, which can affect how they interact with containment structures. For example, some liquids may require diking materials that can withstand corrosive effects, while others may need materials that can manage flammable substances. Compatibility ensures that the dike effectively contains the spill without failing due to reactions between the dike material and the spilled substance. This careful selection is vital for preventing further environmental damage and ensuring safety during response operations.
