Which list comprises forms of contamination?

• A. Vapor, Liquid, Aerosol, Solid
• B. Hot Zone
• C. Warm Zone
• D. Cold Zone

Answer: (A)

Contamination can exist in different physical forms, and recognizing these states helps you identify how it behaves and spreads. The four main forms are vapor, liquid, aerosol, and solid. Vapor is a gaseous form, while aerosol refers to tiny particles (either liquid or solid) suspended in air. Liquid contamination shows up as splashes or droplets, and solid contamination appears as dust or particulates. The option that lists Vapor, Liquid, Aerosol, and Solid includes exactly these states, so it’s the correct choice. The other options describe zones used in decontamination workflows (hot zone, warm zone, cold zone) rather than the forms contaminants can take, so they don’t fit the question.
