If I can cite the number one reason people become overwhelmed when even thinking about putting aside an emergency food supply, it is the perceived sense of urgency that it all needs to be done right now. And this, for many, results in complacency and inaction. Don’t fall into this trap. Begin with a three day supply and gradually build that up to a week. After that, add to your emergency food supply week by week until pretty soon, you have three months of food stored away for you and your family.
In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sun glasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.
My number one tip, though, is to go through your cupboards and closets and remove those items that are duplicates, that you rarely use, or that you do not use at all. For example, in your kitchen, how may different pots and pans do you need? My guess is that you use the same two or three over and over again. Stow the extras in the basement, attic, or garage, or give them away to charity. Trust me, they will not be missed. The same thing applies to seldom used clothing, shoes and sports equipment.
High-sugar energy bars. Grocery store brands have limited shelf life, but several prepper-targeted, Mylar-packed varieties can last 5-10 years. Such products are inexpensive (~300 kcal per dollar), convenient, and energy-dense (~2,000 kcal per pound). On the flip side, they are probably pretty nauseating as your primary food. Imagine living solely off Jelly Bellies for a week.
So, let's start from the beginning! Throughout much of the recorded history, the monetary systems of the western world employed so-called commodity money, generally settling on coins minted out of silver or gold. The two metals were favored because of their nearly universal appeal, and because of their inherently constrained, labor-intensive supply. In this system, early prices likely reflected the worth of a particular good compared to the valuation of the coin as a non-monetary commodity. Over time, the exact "melt value" of the coins started to matter less, and the currency functioned as a more abstract medium of exchange - but its precious metal content stabilized the economy by ensuring that the coinage had an inherent and lasting value, even if the issuing state simply vanished from the map.
What you are going to get is a list of 20 items that can easily be purchased at your local grocery store, warehouse club and surprisingly, even online at Amazon. They can be purchased in one shot, all at once, or you can pick up one item from the list each week over a period of twenty weeks. The choice is yours. All I ask is that you consider getting each of the items on the list and that you also consider getting started sooner rather than later. I promise you that this will be easy.
Stocking a survival kit is a very personal procedure. Your life may depend on your choices at some point, so you’ll want to ponder the potential disasters you may face and do your best to assemble the items that will help you survive. But, if you start with the items listed above, add in those which will address your personal needs and carry them in a sensible container, you’ll likely keep yourself alive and return home with a great story.
For personnel who are flying over large bodies of water, in additional to wearing a survival suit over cold water, a survival kit may have additional items such as flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still or chemical desalinator kit now replaced by a hand pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.
Lifeboat survival kits are stowed in inflatable or rigid lifeboats or life rafts; the contents of these kits are mandated by coast guard or maritime regulations. These kits provide basic survival tools and supplies to enable passengers to survive until they are rescued. In addition to relying on lifeboat survival kits, many mariners will assemble a "ditch bag" or "abandon ship bag" containing additional survival supplies. Lifeboat survival kit items typically include:
