A dike around a pesticide storage area should contain the tank volume plus what percentage?

• A. 5
• B. 10
• C. 25
• D. 50

Answer: (B)

Containment for a pesticide storage dike must be sized to hold the entire contents of the largest tank plus a buffer for spills and precipitation. This buffer is typically 10 percent of the tank’s volume, giving a total capacity equal to the largest tank volume plus 10 percent. The extra space accommodates potential leaks or spills and any rainwater that could wash into the dike, helping prevent environmental contamination. A smaller cushion wouldn’t reliably cover leaks or rainfall, while larger cushions are more than usually needed; 10 percent provides the appropriate safety margin.
