Which of the following is a type of decontamination?

• A. Operational
• B. Containment
• C. Isolation
• D. Evacuation

Answer: (A)

The main idea is how decontamination is categorized for quickly reducing contamination in real-time operations. Operational decontamination is the rapid, field-level cleaning used as people or equipment move from dirty to clean areas—think removing outer clothing, brushing or wiping off loose contamination, and performing a quick rinse at the point of transfer. It’s designed for speed and practicality, not a full, thorough cleanup, to prevent contaminants from being carried into safer zones. The other choices describe protective actions or strategies (preventing spread, separating people, or moving them away from danger) rather than actual decontamination of the person or gear. Therefore, this type of decontamination best fits the description.
