Long Term Storage (LTS) is a different game from storage for general preparedness. For the former, you are talking 20 or more years, while the latter is generally standard shelf life, or about 2-5 years. Yes, I am (over) simplifying things, but…
For me, I have two major reasons for doing LTS work. The first is that I think it a very good idea to have some basic stocks on hand for emergencies and disasters. I know I would like to eat during such, and that there might be others who do as well that I might can assist.
The second reason is that I am a cheap [male offspring of unwed parents — trying to clean up my act a bit as clergy and others may be reading this], er, Scottish, and like buying bulk. Let’s face it, times are tight for us all, and for me having to take early retirement (stupid lightning) puts me on a very tight budget. So, I buy bulk and don’t want to waste any of that food. Bit more on that discussion soon.
There are four major materials used for LTS containers: glass, metal, plastic, and concrete. Yes, I did say concrete. For now, let’s take them in that order and look at some of the pros and cons of each.
Glass, and pottery before it, has been a staple of LTS for literally eons. One still comes across articles detailing how a sealed bit of pottery was found to contain still-edible food (honey turns up fairly frequently) even after a thousand or so years. Glass, and the glass canning jar, really did revolutionize food storage with the advent of more modern types of rubber for sealing.
Glass is durable and has a long shelf-life of its own. Which means the jar you use today could be used by your child or grand-child many years from now. The clarity lets you keep an eye on what’s inside and spot problems before opening. The downside to glass (and pottery) is that it is quite brittle/fragile, which limits emergency utility.
Metal has also been around for a while, and offers great strength and protection to the contents. You have metal boxes and cans available in a wide variety of sizes and shapes. Above is a large can and an ammo box I repurposed as a humidor. Sadly, I am out of good cigars for it.
The drawbacks to metal include bulk/weight, expense, and that coatings are often required as some metals and/or the sealing agents used on them are toxic and/or will corrode easily. Some of the early cans had more than a little bit of lead in them, and poisoned those who ate their contents. Modern cans have little to no lead (depending on where you are in the world) and are often lined to prevent corrosion, especially from acids (think tomatoes for just one example).
Before I forget, I have a larger ammo can that can be used to store electronics and such that I want to shield from radiation of various types and intensities. This includes from sources man-made or from that huge fusion furnace that lights our world — the sun. You don’t have to get to the level of a Carrington Event (or worse) before it becomes good to tuck things away. Given some of the recent strong eruptions from the Sun (so far pointed away from us), might want to think about that.
Plastic is probably the most used modern material for LTS and general storage. It is travel cases, storage cases, coolers, food-safe buckets, mylar bags, and much, much more. There are many different types of plastic out there, and each has advantages and disadvantages.
On the pro side, plastic is relatively inexpensive, depending on formulation quite durable, stronger and more resistant to impact than glass, and lighter than metal or concrete. There are a number of food-safe options available for food and other storage. Just my take, but I tend to use food-safe for as much as possible so I can re-use it at need. For example, in an emergency or disaster, that storage container can be re-used for storage, washing, food prep (soaking, brining, etc), and more. Don’t just think of the initial use, consider that when one moves into disaster territory what you have may well be all you have for some time to come. Make it count.
The con side is that plastic can and and will shatter, often does not take well to sunlight and heat, and is not something you really want to stack, particularly 5-gallon or larger containers. Stacking will result in structural failure, so just don’t do it. Yes, I do speak from experience.
Oh, keep in mind modern coolers/ice chests can be used to store both food and non-food items. I know more than one person who uses them as a humidor for cigars. Load in boxes of cigars, throw in some humidity packs, seal the drain plug, and things are good for months before you have to think about replacing the humidity packs. Add in desiccant packs and you can store books, electronics, and much more in a controlled environment. That way, you not only have the contents, but you have those coolers for use in an emergency or disaster. Just a thought.
Our final category of material is concrete. No, not thinking concrete briefcases or such, but when looking at storage that involves less-than-optimal conditions, certain varieties of disaster, or the need to store things such that they are not obvious, concrete — especially pre-formed concrete products — can be a good way to go.
As I noted here, in the opening of Lucifer’s Hammer Niven and Pournelle had a character loading carefully packaged books into a modified pre-made septic tank. With the normal input/output openings sealed, such makes a very good and durable underground storage unit. I’ve even heard of people using several linked together for shelters. Thing is, with the number of pre-formed concrete pipes, cisterns, etc. you can find something of almost any size for your storage needs. Think also that burglars or other not-nice people are not going to think to check something that has pipes running in and out or appears to be an active septic tank within a basement or pump house, etc. The metal that is in most such pre-formed items is also going to diminish the effectiveness of metal detectors and such when used indoors. Something to think about for outdoor use. Just a thought.
Tomorrow, I hope to take a look at long-term food storage and a bit of my take on the subject. There is no one right way or system, individual tastes vary, but within that one does need to provide for complete and balanced nutrition. For me, I like to survive in style as much as possible, so I may have a few thoughts on how to make friends and have a bit for trade. More soon.
Getting hit by lightning is not fun! If you would like to help me in my recovery efforts, which include moving once we have medical issues cleared up, feel free to hit the fundraiser at A New Life on GiveSendGo, use the options in the Tip Jar in the upper right, or drop me a line to discuss other methods. It is thanks to your gifts and prayers that I am still going. Thank you.
