Which setup is most suitable for quickly decontaminating a large crowd?

• A. A system employing low-pressure high-volume showers
• B. A system using only dry decontamination
• C. A system using high-pressure broad jets everywhere
• D. A system requiring full protective suits

Answer: (A)

In mass decontamination, the goal is to remove contaminants from a large number of people quickly and safely. Low-pressure, high-volume showers achieve that best because they cover many individuals at once and deliver a large amount of water without creating strong jets that can splash, aerosolize, or drive contaminants deeper into skin or clothing. This setup allows rapid washing and rinsing across the crowd, diluting and flushing away hazardous materials in a short time, which is essential when dealing with many evacuees. Dry decontamination, while useful in some situations, is slower for large groups because it relies on individuals scrubbing or wiping themselves, which takes more time and coordination. High-pressure broad jets could spread contaminants around and increase splash and inhalation risks, making them less safe for mass decon. Requiring full protective suits adds time and complexity, reducing throughput and practicality for quickly processing a crowd.
