Letter Re: Firefighting Equipment for Rural Homes and Retreats, and Comments of Geothermal Heating

Hi Jim, I thought it prudent to add a bit to Mr. Savage’s fire fighting equipment article. It touches two topics worth mentioning. In the article, Mr. Savage recommends a fire truck, bladder, tank, etc… for firefighting. I have no problem with this unless it is winter. Trying to pump this much water on as “as need” basis in the event of a fire is obviously not going to work as well. Storing the water in a “non-potable” type container clearly marked, one could add the appropriate amount of RV antifreeze to the tank to keep from bursting your firefighting …


Two Letters Re: Advice on Enhancing Cool Basement Food Storage

James: For those looking to create stable and “passively” cool storage in a basement, the book “How and Why to Build a Wine Cellar” by Richard Gold is a well-thought, meticulously engineered solution to many of the same issues faced by those seeking to store food at stable, cool temperatures. Regards, – Ben JWR: I have spent much of my adult life in the construction industry and through experience and educational seminars, etc. I have acquired a substantial amount of knowledge concerning moisture intrusion into structures. Water is the main source of problems in construction. Keeping it in, keeping it …


Letter Re: Advice on Enhancing Cool Basement Food Storage

Mr. Rawles: We are building a new house with a basement. I am planning a food storage room in the corner of the basement that is the furthest underground. Can you guide me with details about how to plan that room, mainly about temperature. I know that cooler is better. The basement has poured cement walls. Should I insulate the [other] two walls [that are partitions] inside the basement? The rest of the basement will be heated, should I leave the vents out of that room all together? What about the vent that pulls air in for circulation? We are …


Letter Re: Advice on Where to Learn Practical, Tactical Skills

1

Dear Jim: As my confidence in the dollar depreciates and my desire for skills increases, I’m wanting to convert FRNs into hands-on knowledge. What weeknight or weekend workshops would you recommend? Are there any places where you can learn Army Ranger skills without joining the military? Animal husbandry, and so on? – Spencer JWR Replies: There is a tremendous wealth of free or low-cost classes available–enough to keep you busy every weekend of the year if you are willing to drive a distance. If you have time and just a bit of money, you can get some very well-rounded training …


Nuclear, Chemical or Biological Disaster Preparedness, by Brian A.

One of the recent phrases the media has used almost to exhaustion is, “dirty” bomb. A dirty bomb, or radiological dispersion device (RDD) is basically an explosive device with some element of radioactivity attached, or some other means of distributing radioactive particulate matter. When detonated, it releases radiation in the form of dust or debris, which is harmful mostly when inhaled, or introduced into the body by other means, (eyes, open cuts, etc.). The main terror use of such a weapon would be to contaminate emergency services workers responding to the initial blast. In the 1990s, Chechen rebels reportedly placed …


Chimney Construction, by PrepNow

I would like to offer some information about my experience with chimney construction and creosote build up. This information does not apply to the typical suburban open fireplace. What I’m talking about is a wood-burning stove designed to heat your home or shelter. There are a number of manufactured fireplaces available that are designed to regulate the amount of combustion air traveling into the firebox and consequently the control the actual burn. These are the most efficient and are the type that we would be using in a structure designed to ride out the future storm. Construction of the chimney …


Letter Re: Observations on the Recent Missouri Ice Storm

Mr. Rawles, I live in Southwestern Missouri. Did you followed the ice storm that buried the Midwest? We got hit pretty hard. We get hit hard every four or five years. Which brings me to my point. I have never seen so many unprepared people in all my life. After day two of the ice storm power was out (for a month in a lot of places like Springfield). There were no gas cans to be found at any store. Batteries, disposable propane bottles, flashlights, milk, and meat were missing from the shelves of every store. Even Wally World [Wal-Mart] …


Letter Re: Observations on the Recent Oklahoma Ice Storm

Jim: Well, I just got back online. I had to go up to the roof and thaw the wireless [Internet] antenna with a heat gun. It seems the ice grounds out the antenna. It was an easy fix with my heat gun for heat shrink tubing. More precipitation is on the way but colder. It will probably just be snow. We never lost power but were ready anyway. I have friends with no power and they have been without power for days and no idea when it will be back on. The further out you live, the less chance of …


Pre-Crisis Survival Skills, by D.A.L.

Pre-crisis survival skills: The only tool more valuable than knowledge is an attitude of self sufficiency. The mere willingness to provide for your own needs can pay off everyday, even absent any “end of the world as we know it” event. In fact, simply being willing to provide for your own needs can pave the way for not only learning valuable skills, but saving money to boot! By way of example let me tell you about a recent experience with the steam heating system at my lady friend’s house. It is a Victorian house and the main boiler furnace was …


Letter Re: First Hand Observations on the Recent Pacific Northwest Wind Storm

Background: I am an 11 year veteran peace officer and survivalist, or in more politically correct terminology, a POP – Preparedness Oriented Person. I work in a moderate sized city in the Seattle area. On 14-15 December, the Tacoma-Seattle-Everett metropolitan area suffered one of the most deadly and damaging windstorms in recorded history. The storm easily eclipsed the last major deadly blow on Inaugural Day, 1993. That storm had been identified as a “once in a century” type storm. At the peak, over 1 million people did not have power. This storm was modeled and forecasted with accuracy five days …


Two Letters Re: Build Your Fallout Shelter From Barter Goods, by Mr. Yankee

Jim: Regarding Mr. Yankee’s article: Salt in some water softeners is potassium chloride, not sodium chloride. Both are ‘salts’ but they behave differently. Be sure you are storing the sodium chloride variety.- SF in Hawaii   Mr Rawles, Hope this finds you and your family doing well. I’m not sure if this link has been disclosed in the past, and I am certainly no expert in this field, but this seems like a well thought out presentation for a fallout shelter. Keep up the good work, – R.C.


Three Letters Re: Build Your Fallout Shelter From Barter Goods, by Mr. Yankee

Hi Jim. Just felt the need to re-emphasize the point you made with regard to Mr. Yankee’s ideas about an improvised fallout shelter. First, I applaud his view that one should not count on being able to pull together an adequate expedient shelter when the need arises. As simple in theory as it seems, in practice, few would end up with a shelter they would want to rely on to save the lives of their loved ones. Second, as far as the point you made, Jim, it is indeed very important to over-engineer any sort of structure that will be …


Letter Re: Emergency Shelter Air Filtration

Hey Jim, Just a couple of articles [over at the Alpha Rubicon site] that you might find interesting: Safe Room Fan and, HEPA Filter Regards, – S.C. JWR Replies: For any SurvivalBlog that might have overlooked it at my Links page, I highly recommend the wide variety of practical free references available at the Alpha Rubicon web site.


Letter Re: Emergency Shelter Air Filtration

Most of the modern home vacuum cleaners have pretty decent high efficiency particulate air (HEPA) filters in them nowadays. Assuming you still have power (a big if) you could seal a room to the best of your ability and leave your vacuum cleaners running (with the air intakes off the floor). If you have a bag type, remember to put a new bag in. Presto, filtered air, McGyver style. If all you have is an older style vacuum cleaner with no filter, then put a damp rag (and keep it damp) over the air intake, but be careful not to …


Letter Re: Storing Coal for Home Heating at Your Retreat

Jim: Regarding he recent thread on coal storage, old factories and military installations that used coal (some barracks were coal heated and still have bins outside) often have large amounts (suitable for the survivalist or amateur blacksmith) of coal that’s not cost-effective for the operation to do anything with. If one offers to clean it up, it might be available free. I know there’s lots of anthracite coal outside old barracks at Fort McCoy, Wisconsin. Perhaps someone in the area would be able to salvage it. I’d appreciate a load for my forge for the referral if anyone does this. …
