Diversion, diking, and retention are all techniques used in:

• A. Confinement
• B. Containment
• C. Evacuation
• D. Dilution

Answer: (A)

Diverting flow, building dikes, and creating retention areas are all ways to keep a spilled hazardous material within a defined boundary. Diversion channels redirect the material away from drains or sensitive areas so it doesn’t spread further. A dike or berm acts as a physical barrier to contain the spill within a designated area. Retention structures—like ponds or tanks—hold the material so it can be contained and cleaned up without uncontrolled spread. This focus on bounding and controlling the release is what confinement is all about. Evacuation moves people away from danger, dilution tries to reduce hazard by mixing with another substance, and containment is about stopping the material from leaving its source or limiting its release, which is broader than the specific boundary-checking actions described here.
