What is the purpose of containment measures such as dikes or berms?

• A. To contain spilled liquid and prevent spread to drains, water, or adjacent areas.
• B. To improve the appearance of the site.
• C. To measure spilled volume with precision.
• D. To provide a barrier for wind.

Answer: (A)

Containment measures like dikes or berms are designed to keep spilled liquids from spreading beyond a controlled area. By surrounding the spill, they create a physical barrier that prevents runoff into drains, waterways, soil, or adjacent spaces, reducing environmental contamination and exposure risk. This containment gives responders time to stop the source, recover the liquid, or apply absorbents without the spill migrating to sensitive areas. They are part of secondary containment strategies and are chosen based on the product’s properties and the site layout. They are not intended to improve appearance, measure volume, or serve as wind barriers. The main goal is environmental protection and safety by keeping the liquid contained at the source.
