Quick Answer
When choosing iodine tablets for survival, consider the concentration of iodine, the expiration date, and the amount of water they can treat.
Concentration and Effectiveness
When selecting iodine tablets, ensure they contain a sufficient concentration of iodine, typically 2.5% or 8.25mg per tablet. This concentration is effective against Giardia and Cryptosporidium. It’s also crucial to note that the tablets should be able to treat a sufficient amount of water, typically 1 liter per tablet. This will help you treat larger quantities of water, especially in emergency situations.
Expiration Date and Shelf Life
Iodine tablets have an expiration date due to the instability of iodine. When choosing iodine tablets, verify the expiration date and ensure it is within the next 3 to 6 years. This ensures the tablets retain their effectiveness. Always check the packaging for any signs of damage or degradation, which can compromise the iodine’s potency.
Storage and Handling
Proper storage and handling of iodine tablets are essential to maintain their effectiveness. Store them in a cool, dry place, away from direct sunlight and moisture. When using the tablets, ensure you follow the instructions carefully, and do not mix them with other substances or contaminants. This will prevent the iodine from reacting with other chemicals or becoming ineffective.
