A survival kit is a package of basic supplies and tools prepared in advance to help people survive in an emergency situation. Survival kits are sold in many forms, variety of sizes and assemblies, ranging from MINI survival kit, consisting of only the bare minimum of essential emergency supplies, to the ULTIMATE survival kit that can help you stay alive in almost any difficult situation. The most common elements of a survival kit provide emergency food and water supplies, basic shelter and products to keep people warm, simple medical kit, signal sources, and multifunctional tools such as the Swiss army knife.
Those emergency preparedness kits are designed to help people survive at least the first critical 72 hours after a disaster and assist them in finding help. According to Red Cross recommendations the survival kits should be easy to carry and simple to use.
