What step follows shaking the bag for one minute when using iodine tablets to disinfect water?

• A. Let the bag sit for 10 minutes
• B. Let the bag sit for 3 minutes
• C. Swirl the water in the bag for 1 minute
• D. Pour the water into the treatment bag

Answer: (B)

After shaking the bag for one minute to ensure adequate mixing of the iodine tablets with the water, it is important to let the bag sit for a specified duration to allow the iodine to effectively disinfect the water. The correct step following the shaking process is to let the bag sit for 3 minutes. This waiting period is crucial because it provides enough time for the iodine to kill any harmful microorganisms present, making the water safe for consumption. Letting the water sit for this duration allows the iodine to fully dissolve and disperse evenly throughout the water, ensuring maximum efficacy in the disinfection process. This method is part of standard field sanitation practices, ensuring that all safety measures are adhered to when treating drinking water in the field.
