Many preppers are storing calcium hypochlorite because a small quantity of this chemical enables you to create enough bleach to purify a typical family’s drinking water for YEARS. The use of calcium hypochlorite also solves the problem posed by bleach losing it strength over time. Anyone choosing to store this volatile and potentially dangerous chemical should consider the following measures…
1) Be certain that any calcium hypochlorite you purchase has calcium hypochlorite as the only active ingredient. Some sources also contain highly toxic additives, such as algaecides added to some brands of pool shock.
2) Store the original packages in a cool, dry location, and at least 30 feet away from liquid petroleum products and food. Place the original packages in well-sealed glass or plastic containers with one or more desiccant packs to reduce moisture.
3) Once every few months open and re-seal the outer container to release any slight amount of chlorine gas that may have accumulated (CAUTION: This should be performed in a well-ventilated area).
Due to its potential to purify very large quantities of water the day may come when calcium hypochlorite is worth much more than its weight in gold.
Our book, “When There is No FEMA”, provides complete instructions not only for the storing and handling of calcium hypochlorite, but also for properly mixing it with water to create bleach for water purification.
