Which action is used to physically separate contaminated individuals or zones to prevent spread?

• A. Isolation
• B. Evacuation
• C. Treatment
• D. Monitoring

Answer: (A)

Isolation is the action of physically separating contaminated individuals or zones to stop the contaminant from spreading. It creates defined barriers and controlled access, so people and clean areas aren’t exposed to the contaminated area. This often means closing off compartments, using designated entry/exit points, and employing decontamination and PPE to maintain a clean boundary between safe and contaminated spaces. By keeping the contamination contained, you prevent it from migrating to other parts of the ship or facility, which is the core purpose of this response. Evacuation moves people away from danger, but it doesn’t inherently contain the contamination in place or stop its spread within the current area. Treatment focuses on providing medical care to exposed individuals, not on containment. Monitoring is about observing and detecting exposure or contamination, not preventing spread through physical separation.
