How is gross decon accomplished?

• A. By physically removing the contaminant.
• B. By chemical neutralization
• C. By containment only
• D. By monitoring only

Answer: (A)

Gross decon is the rapid physical removal of contaminant from a person, equipment, or area. The goal is to lower exposure quickly by stripping away and washing off the contaminant rather than trying to neutralize it chemically or simply contain it. In practice, that means removing contaminated clothing, and using water or a basic rinse to wash away the contaminant, then moving the items or a person to a cleaner area. After this quick step, a more thorough fine decon often follows to address any residual contamination. Chemical neutralization would involve changing the contaminant chemically, which isn’t the same as physically removing it; containment alone keeps the contaminant in place without removing it, and monitoring alone does not reduce contamination.
