Common preparations include the creation of a clandestine or defensible retreat, haven, or bug out location (BOL) in addition to the stockpiling of non-perishable food, water, water-purification equipment, clothing, seed, firewood, defensive or hunting weapons, ammunition, agricultural equipment, and medical supplies. Some survivalists do not make such extensive preparations, and simply incorporate a "Be Prepared" outlook into their everyday life.
The stories of alcoholic beverages historically being safer to drink than unfermented ones are apocryphal at best; however, as any 17th-century sailor would tell you, the addition of some spirits to potable water that's been sitting around for too long will make it much more palatable. Liquor distillation was originally invented in part for medical purposes, and alcohol can be used as a solvent to dissolve medicinal herbs -- and also to knock out patients during good old-fashioned fallout-shelter surgery. High-proof alcohol can be used as an antiseptic, and it does a great job of cleaning wounds and preventing infection.
Other small kits are wearable and built into everyday carry survival bracelets or belts. Most often these are paracord bracelets with tools woven inside. Several tools such as firestarter, buckles, whistles and compass are on the exterior of the gear and smaller tools are woven inside the jewelry or belt and only accessible by taking the bracelet apart.
Every year in the US about 150 people die while out and about in national parks, more than 1,000 die in hunting-related incidents and thousands of backcountry enthusiasts get in deep trouble and require a Search and Rescue team to save them; with dozens of those folks dying while awaiting rescue. Most fatalities are the result of poor preparation. Bad weather descends and people get lost. They wander without water or shelter, often injuring themselves in the process. If they survive they often suffer frostbite, hypothermia, dehydration, trench foot or some combination of them all.
