What are the two types of decontamination?

• A. Operational and Thorough
• B. Operational and Immediate
• C. Thorough and Immediate
• D. Immediate and Delayed

Answer: (A)

Decontamination in a damage control setting is done in two stages: operational decontamination and thorough decontamination.

Operational decontamination is the quick, on-scene step to remove or reduce contaminants so personnel can keep working and limit spread. It focuses on rapid actions like removing outer garments, basic washing, and quick rinses to restore function and safety for immediate duties.

Thorough decontamination comes after the initial step and is more complete. It targets all residual contamination on people, gear, and spaces, often at a dedicated decon station with additional washing, rinsing, and cleaning procedures to ensure nothing remains.

Using both stages together allows you to maintain mission tempo while ensuring full safety—first get contaminants off fast, then finish cleaning thoroughly.
