Which statement about emergency decontamination is NOT TRUE?

• A. It removes the threat of secondary contamination
• B. It removes contaminants that pose immediate threat to life
• C. It is designed to reduce exposure risk to responders
• D. It should be conducted quickly at the scene

Answer: (A)

Emergency decontamination aims to remove the contaminant from the patient to limit harm and prevent exposure to responders and bystanders. It is focused on removing contaminants that could cause immediate injury, and on reducing the chance that responders come into contact with the agent. It should be done quickly at the scene to minimize exposure and prevent spread.

However, the idea that it can remove the threat of secondary contamination is not accurate in all cases. Secondary contamination risk can persist because contaminants may be on clothing, equipment, or in runoff, and incomplete decon or improper containment can allow cross-contamination to occur despite on-scene decon efforts. So while decontamination greatly reduces the risk, it does not guarantee complete removal of secondary contamination.
