Which item is NOT listed as part of Technical Decontamination steps?

• A. Dilution
• B. Equipment drop
• C. Overglove/Boot removal
• D. PPE Removal

Answer: (A)

Technical decontamination focuses on removing contamination from personnel and equipment at the boundary with controlled, physical removal and cleanup. Staging or dropping contaminated equipment at the boundary prevents carryover into clean areas, and the doffing sequence—starting with protective layers like outer gloves and boots and finishing with full PPE removal—minimizes the chance of skin contact with residual contaminants. Those actions are core parts of a technical decon procedure. Dilution, while it can be used in other decon contexts to lower contaminant concentration, is not a listed step in the technical decontamination sequence. Therefore, dilution is the item that does not fit as part of the formal technical decon steps.
