• C. A chemical neutralization step.
• D. A final rinse with deionized water.

Answer: (A)

Gross decontamination is the rapid, high-volume decon process used to quickly remove the majority of contamination from responders and patients. The goal is to strip away most of the contaminants in a short amount of time, prioritizing speed to reduce exposure and limit spread before more thorough cleaning or medical care is provided. This is typically done at the scene or as people enter the medical area, using large amounts of water (and simple cleaning agents) to wash away contaminants rather than performing meticulous or site-specific cleaning. It’s not about slow, detailed cleaning of equipment, chemical neutralization, or a final rinse with deionized water—that level of cleaning comes later in more thorough decontamination steps.
