How many decon types are described in the material?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Decontamination in the material is described as a two-stage process. The first is gross decontamination, a rapid, scene-level cleanup intended to quickly reduce exposure by removing the bulk of contaminants—usually with a water rinse or wipe-down and removal of contaminated clothing. The second is technical decontamination, a more thorough cleaning carried out in a controlled area by trained personnel, using appropriate cleaners, brushes, rinses, and proper PPE to remove residual contamination from skin, gear, and equipment. The material outlines these two distinct approaches, so the number described is two. Any other terms you encounter are typically more specific steps within these two broad categories rather than separate decon types.
