Which term describes decon that is urgent, field expedient, and applied to direct exposure?

• A. Emergency Decon
• B. Mass Decon
• C. Technical Decon
• D. Final Decon

Answer: (A)

The situation tests understanding of the on-scene decontamination levels and which one is meant for immediate, field-level action on someone directly exposed. Emergency decon is designed for rapid, improvised decontamination right at the incident site to quickly reduce contamination on skin or clothing that a person is directly exposed to. It uses simple methods and minimal equipment, often involving removal of contaminated clothing and a quick rinse or wash so the exposed person can be treated or moved without carrying contamination further. This is exactly what “urgent, field expedient, and applied to direct exposure” describes.

Mass decon targets large numbers of people and focuses on throughput, often with higher-flow water and structured procedures. Technical decon is thorough and performed with specialized procedures and equipment, usually for contaminated equipment or areas and often after initial stabilization. Final decon is done later, to remove residual contamination before releasing individuals to a clean area.

So the term that matches urgent, field-ready decon applied to direct exposure is emergency decon.
