Diking is a safeguard used to minimize toxic releases.

• A. True
• B. False
• C. It depends on the context
• D. Not sure

Answer: (A)

Diking is a physical containment measure that provides secondary containment for liquids, capturing spills to limit the release of hazardous materials. It creates a bounded area around storage tanks or process zones so that if a leak or overflow occurs, the liquid is contained within the dike and cannot spread to soil, drains, or nearby waterways. This containment buys time for detection, response, and cleanup, thereby reducing the potential offsite impact and severity of a toxic release. Dikes are a passive engineering control and are most effective when designed with adequate capacity and maintenance, and when used for liquids. They don’t eliminate the release itself, but they lower its consequences. In contexts where liquids are involved, this containment approach is a standard safeguard to minimize releases.
