Designing a containment basin involves several considerations to ensure its effectiveness and compliance with regulations. Key factors include: - Capacity: The basin must be able to hold at least the volume of the largest container within the area it serves, plus additional freeboard to accommodate rainfall or firewater. - Location: Positioned to capture any potential spills or leaks from storage tanks, reactors, and piping systems. - Compatibility: Ensuring the materials used are compatible with the chemicals they will contain to prevent degradation. - Drainage and Cleaning: Incorporating features that allow for easy drainage and cleaning to maintain the basin's functionality over time.
