Which component is prohibited from passing through adjacent diked areas or impounding basins?

• A. Piping
• B. Valves
• C. Electrical cables
• D. Gaskets

Answer: (A)

A key safety rule here is preventing a spill from bypassing containment. Diked areas and impounding basins are designed to hold oil within their boundaries if a leak occurs. A piping run that passes through the boundary between adjacent diked areas creates a direct path for product to move from one diked area to another if a leak develops, effectively defeating the containment system. Because of that, piping is prohibited from crossing or passing through these boundaries. Electrical cables, valves, and gaskets don’t by themselves create a continuous spill path between diked areas in the same way piping does, so they are not treated as the same cross-boundary risk when installed with proper protection and sealing.
