How many capfuls of calcium hypochlorite solution are needed to disinfect water in an NBC canteen cup?

For disinfecting water in an NBC (Nuclear, Biological, and Chemical) canteen cup, one capful of calcium hypochlorite solution is the appropriate amount needed. This guideline is based on the recommended dosage to effectively kill pathogens in a volume typically associated with such cups, ensuring safe drinking water while avoiding an excessive concentration of chlorine, which could be harmful.

Calcium hypochlorite is a commonly used disinfectant due to its effectiveness against a broad spectrum of microorganisms, including bacteria and viruses. The correct dosage is crucial to balancing safety and efficacy; too little may not effectively disinfect the water, while too much could pose health risks or lead to an unpleasant taste. Therefore, adhering to the guidance of using one capful ensures optimal disinfection while maintaining water quality for consumption in military settings.
