Which decontamination stage would be used after initial exposure to remove contaminants from equipment and personnel?

• A. Primary Decontamination
• B. Decontamination
• C. Secondary Decontamination
• D. Emergency Decontamination

Answer: (C)

Decontamination after exposure is done in stages so contaminants are removed progressively while protecting people and gear. The stage used to thoroughly remove contaminants from equipment and personnel after the initial exposure is secondary decontamination. This step happens in a controlled area beyond the immediate danger zone and involves more complete washing, rinsing, and decontamination of both skin and gear. The goal is to eliminate residues that survived the quicker initial decontamination and to prevent any transfer of contamination as you move the person or equipment to cleaner areas, often before doffing PPE. Emergency decontamination is the rapid, on-the-spot removal to limit further exposure and spread; primary decontamination is the first organized decon close to the hot zone; a general term isn’t specific enough for the staged process.
