Which method best supports rapid decontamination for many people?

• A. Low pressure high volume shower
• B. High pressure concentrated spray
• C. Individual cleansing stations
• D. Dry cloth wipe only

Answer: (A)

In mass decontamination, you want to rinse many people quickly with enough water flow to remove contaminants from skin and clothing without creating risks from splashing or aerosolization. A low pressure, high-volume shower system does just that: it provides a large amount of water over a broad area, allowing many individuals to move through a decon line and be rinsed rapidly. The gentle pressure reduces the chance of forcing contaminants deeper into skin or spraying them into the air, which helps protect both victims and responders while maintaining a fast throughput. High pressure concentrated sprays, while effective for targeted cleanup, slow down throughput and can spread contaminants through splashes or aerosols, making them impractical for mass decon. Individual cleansing stations limit the number of people who can be decontaminated at once and require more personnel and time, reducing overall speed. Dry cloth wipe only leaves contaminants on the skin and surfaces and can lead to spreading the residue as people move, making it ineffective for rapid, wide-area decontamination. So the low pressure high-volume shower is best suited to rapidly decontaminate large numbers of people.
