Which term describes the transfer of a hazardous material to people, equipment, or the environment in greater than acceptable quantities?

• A. Exposure
• B. Spill
• C. Containment
• D. Contamination

Answer: (D)

Contamination describes the presence or transfer of hazardous material into places it shouldn’t be—in people, on equipment, or in the environment—at amounts that exceed safe or acceptable levels. It focuses on the material being in the wrong place and the quantity being too high, which creates risk for exposure and harm. Exposure is the actual contact that can lead to harm, often resulting from contamination. A spill is the release event itself, while containment is about preventing spread. So contamination best captures the idea of material being transferred into undesired locations and quantities.
