These 4 oz. emergency drinking water pouches provide critical clean water in a severe emergency or disaster. They are U.S. Coast Guard approved and have a 5–year shelf life, reducing the need for replacement and lengthening the life of any emergency kit. Each pouch is extremely durable, compact and lightweight. The 4 oz. size provides important portion control for groups or individuals in an extended emergency. Pouches are easily opened. In an emergency, each person should drink a minimum of 8oz. (2 pouches) per day. A box of 64 pouches provides a 3–day minimum supply for up to 10 people. Some experts recommend storing up to 1 gallon per person per day for drinking, cooking, and sanitation. Add additional pouches to your LifeSecure™ Emergency kits to increase your supply of water beyond the minimum requirements.
