Retention is defined as which action?

• A. Actions to direct and control movement to a less harmful area
• B. Actions to contain a liquid in an area where it can be absorbed, neutralized, or removed
• C. Actions to prevent or limit the flow of liquid past a certain area
• D. Actions using raised embankments or barriers

Answer: (B)

Retention means keeping the spilled liquid confined to a defined area so you can deal with it directly—absorb it, neutralize it, or remove it for disposal. The purpose is to hold the material in place long enough to treat or clean it up, rather than simply moving it somewhere else or just blocking its flow. In practice, this is achieved by creating a controlled space for cleanup activities, using absorbents or other methods to manage the liquid in one area.
