The size of the decon zone is determined by which factor?

• A. Weather
• B. Time of Day
• C. Decontamination Agents
• D. Terrain

Answer: (C)

The amount of space you allocate for the decon zone hinges on the decontamination agents and the method you’re using. Different agents require different procedures, contact times, and containment needs, which in turn dictate how much room is needed for the decon setup, including staging areas, shower or wipe stations, runoff containment, and the doffing zone. If you’re dealing with a highly persistent or hazardous agent that needs longer contact times and more thorough rinsing, you’ll need a larger decon zone to safely manage the process and prevent cross-contamination. Conversely, a simpler, quicker decon with a less demanding agent generally requires less space. Weather, time of day, and terrain can influence practical setup, but the decontamination agents themselves drive the primary sizing.
