Which statement about decontamination is correct?

• A. Decontamination should be delayed until contamination is confirmed.
• B. Immediate decontamination is essential for suspected contaminated individuals to prevent exposure.
• C. Decontamination is only for chemical exposures.
• D. Decontamination is optional.

Answer: (B)

Immediate decontamination is essential to prevent exposure to others and responders when there is any suspicion of contamination. Contaminants on skin or clothing can be transferred through contact, shedding, or movement, so starting decontamination right away greatly reduces secondary exposure. Waiting for lab confirmation wastes critical time and can allow the contaminant to spread further. Decontamination is not limited to chemical exposures; biological and radiological contaminants also require prompt cleaning to limit spread and absorption. It is not optional. In practice, rapid steps such as removing contaminated clothing and washing the skin with clean water (and soap if available) are used to quickly reduce the contaminant load.
