Two Letters Re: Seeking Advice on Swimming Pool Chlorine for Treating Drinking Water

Jim:
I had to write you and correct something that could lead to health damage or even death from the use of chlorine [for water treatment]. People have to know that this use [of chlorine] is for treating water [shortly before use], not long term storage. If you have a water supply that you intend to drink/use within a month, then chlorine (as long as it’s pure – as you so instructed) is fine. But it is not for long term storage!
When water is treated with chlorine, and then sealed in a container, the chlorine degrades over a short time period. Depending on variables (mixture, amount of water, heat, et cetera) this could be as soon as 2-3 months. As it breaks down, it releases chlorine gas, which does nothing to protect your water, but it can cause health problems (obviously) and it will also degrade and weaken your container.
There are products out there that can be used for long term water storage. (Stabilized Oxygen is but one of them.) These products can keep water stored safely for up to five years, with no bacteria or algae growth. – Kurt

 

James Wesley:
I can’t remember where I got this, but thought it might help with the question of “how much” in chlorinating water…..

Chlorination
Two common forms of chlorine compounds can be used, those disinfectants that contain Sodium Hypochlorate (household bleach) or Calcium Hypochlorate (swimming pool chlorine powder). It is very important that Chlorine is added to water at the correct dosage. Firstly, calculate the amount of water in the tank by using the following formula:
3.14 x radius2 x height of water in the tank (meters) x 1000 (The radius is half of the width of the tank)
Once you have calculated the volume of the water in the tank then place 40 milliliters of Sodium hypochlorite or 7 grams of Calcium Hypochlorite for each 1000 liters of water in the tank.
For example, if the tank’s dimensions are 5 meters wide, 3 meters high and there is 2.5 ml of water in the tank, the calculations would be as follows:
Volume of Water in the tank is:
3.14 x (5 x?)? x 2.5 x 1000 (liters)
Volume = 49,062.5 (liters)
40 x ( 49000/1000) = 1960 mils of Sodium Hypochlorite
Or 7x ( 49000/1000) = 343 grams of Calcium Hypochlorite

Because so many readers of SurvivalBlog are interested in establishing survival retreats, I’m in the process of setting up a new SurvivalBlog”sibling” web site that will feature survival retreat real estate listings. These will be both For Sale By Owner (FSBO) and from licensed real estate agents, worldwide. If you have a retreat property for sale, or know of someone that does, here is the deal: To get my new survival real estate web site off to a fast start with a lot property ads, I am offering free two month advertisements for the first 25 sellers that respond. Just e-mail me a brief description (200 words or less) of the property that you have available. (I’ll need detailed description and digital photos, later.) Since this project is still in its infancy I can’t guarantee exactly when the site will be launched, but our tentative goal is to have it up and running sometime in July.

Letter Re: Seeking Advice on Swimming Pool Chlorine for Treating Drinking Water

Mr. Rawles,
I want to buy some pool chlorine crystals for long term storage. Holly Deyo’s book had a formula for purifying large amounts of water with this product, but how would I make a chlorine bleach substitute that could be used to purify smaller quantities of water or as laundry bleach? Is there an amount in grains or grams that could be used to make up, say, five gallons at a time? I know store bought laundry bleach like Clorox has a limited shelf life, so I wanted to be able to make [my own hypochlorite solution.] Thank you for any information you could provide. – CG in North Carolina

JWR Replies: Calcium hypochlorite is available from any swimming pool supply company. A granular (dry powder) “pool shock” product that lists only Calcium Hypochlorite as the active ingredient should be safe to use for water purification. The problem with other varieties is that they include other algaecide or fungicide chemicals that are probably not safe for human consumption. Ditto for using liquid bleach for the same purpose. With those, you want to buy plain Calcium Hypochlorite bleach. Do not buy bleach with fabric softeners, scents, et cetera. Keep in mind that bleach solutions break down and weaken with time (anticipate a 24 month shelf life), but that dry granular bleach stores indefinitely. Here is a quote from an EPA web site: “Granular Calcium Hypochlorite. Add and dissolve one heaping teaspoon of high-test granular calcium hypochlorite (approximately 1/4 ounce) for each two gallons of water [to create a chlorine disinfecting solution]. The mixture will produce a stock chlorine solution of approximately 500 mg/L, since the calcium hypochlorite has an available chlorine equal to 70 percent of its weight. To disinfect water, add the chlorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (16 oz.) of stock chlorine [solution] to each 12.5 gallons of water to be disinfected. To remove any objectionable chlorine odor, aerate the water…”

SurvivalBlog reader Laurelei recently reported that she found the Poolife brand “TurboShock” available $14.85 for five pounds. For purifying drinking water, two of the five pound boxes would constitute a “lifetime supply” for most folks.



Three Letters Re: Firearms Questions from a Distaff Newbie

James,
I wholeheartedly agree with your response. For quite some time now, I have been trying to get family members to visit your web site and make the appropriate investment into their own security in a very similar fashion as you did. I always advise those who inquire about personal/home security that appear to be starting from ground zero, like the ‘Distaff’ writer, to add layers to your security. The easiest quick fix is a big canine. I have five (all adopted from shelters and subsequently trained to get along with each other.) Yes, a canine can be defeated. However, a canine will hear out-of-place noises and will sniff out an intruder long before a human will, especially while you sleep or are distracted (watching television, on the telephone,…). Knowing that you have a threat in your presence is the key to surviving a situation. The first few seconds/minute is the critical window of opportunity for someone to get the upper hand. My advice, go get a nice big dog from a shelter who will protect you with his/her life and will be a constant companion. Better yet, get a few. – flhspete

Jim,
I agree with continual training, especially for adults. No matter how good you think you are, you can be better. The Appleseed Program is great ([sponsored by] Fred’s M14 Stocks out of Shotgun News), as are the more professional programs like Front Sight, et cetera.
But for the children, look at the local 4H clubs, they usually have a shooting class and team for youngsters. (starts at age 6 here locally). Also look at the CMP program, they have youth clubs (and you can get a surplus M1 Garand and a M1 Carbine while supplies last!). And I’m sure there are others like Jr. ROTC, and the Young Marines programs. Train a child up right, and he can hold his own with many adults on the range or in the field.

Not to disagree with you on toy guns, but I was brought up with toy guns as well as my first .22 when I was 8. and my kids have them as well. I don’t think they have any harmful effects, but my kids are taught/trained on the difference between real guns (including BB guns) and toys and obviously on the danger. Airsoft has been a great training aid during the cold and wet season. Amazing how realistic (and expensive) they have become. Toy guns get a bad rap, and its fairly hard to get anything at the local Wallyworld [Wal-Mart], I suppose due to the liberal agenda. Walmart has just phased out real guns here too.
Lastly, one approach that has worked for me with our kids is to control their curiosity regarding guns. Any time my kids want to go shoot, or look at any of the firearms, I stop what I’m doing and go with them. This way they never need to sneak to find one! – Mike the MD in Missouri

JWR Replies: That is an important point about kids being curious about guns. Our approach here at the Rawles Ranch is two-fold: First, we keep all of our guns loaded, and everyone here assumes that they are continually loaded and treats them as such, even on the rare occasions that they aren’t. Second, we don’t try to control our kids’ curiosity regarding gun, we indulge it. Since an early age we have have made it clear to our children that we are always willing to show them how to safely handle, load/unload, and even field strip any of our guns whenever they show an interest. Hiding guns or otherwise treating them as “forbidden fruit” just makes kids curious (and as you say “sneaky”). This has been the root of of many of the rare (but massively publicized) household accidental shootings in modern times.

James:
In response to KB from Mississippi, as an NRA instructor I have to concur with your suggestion about taking an NRA-approved course. I would also offer these suggestions to KB:
-Start with the Basic courses (Basic Pistol, Basic Rifle, Basic Shotgun.) These are the foundation for everything else you’ll do, and cover safety, firearms types and functioning, ammunition types, shooting positions, a basic familiarization course of fire, and different shooting activities to help you maintain and improve your shooting ability. Be sure to take your rifle, and if you don’t have a pistol or shotgun, be sure to let the instructor know. I always bring extras to my classes for those who don’t have their own, or want to try something
different. This also allows a student to make a better informed decision about what gun may or may not be right for them.
-Be sure to take the course with your son, if possible. Many years ago, my Mom took me to the NRA Basic Pistol course to learn more about my Dad’s guns after he passed away. It was the best thing she ever did, for both of us. It is much easier to have a third party teach firearms handling, than someone who has an emotional connection. Trust me on this! (Or better yet, ask my wife!) BTW, my Mom is almost 73 years old and has had her concealed carry permit for almost 20 years!
-Once you have taken the Basic course, I strongly recommend you attend a Personal Protection in the Home course. This goes into more detail about using the gun for personal defense, safety, tactics and strategies for home defense, ammunition types for personal defense, and the laws regarding firearms in your state (this part of the course is taught by a local attorney or police officer.) The course of fire also goes into reloading, shooting multiple targets, and movement. Don’t worry, the instructor will cover everything with you, and won’t make you do anything you don’t feel comfortable doing.
-At this point, you should start looking at more advanced training, such as Front Sight, Gunsite, or Thunder Ranch. I’ve attended Gunsite, and can attest to the quality of instruction one will receive there. As always, there is a cost factor involved with traveling to the big name schools, but there are also some outstanding instructors who travel the country teaching the latest in firearms training. Ones that I have experience with and can vouch for are Lethal Force Institute (Massad Ayoob), Suarez International (Gabe Suarez), Yavapai Firearms Academy (Louis Awerbuck), and Defense Training, International (John Farnam). Often, they will be somewhere close by at some point during the year, which will require much less in terms of traveling and money outlay, without sacrificing the quality of training you will receive.
I wish you luck with your journey, truly. I tend to be pretty passionate about this subject, and I apologize for the long winded letter. Don’t be afraid to ask for help, that’s what we’re here for. Regards, – Steve in Iraq

Letter Re: Eye Protection, Flushing, and Infection Treatment

One thing I haven’t seen on your blog is eye treatment. Nothing can put you out of action faster than an eye problem. Recently, I developed a bacterial infection in my right eye which was treated with a prescription oral antibiotic. I also used eye drops to help lubricate the eye and relieve some of the irritation. There are many different eye drops available. I used Allergan Refresh Tears which I bought at Costco. For my situation, my doctor said it was a good choice. My doctor informed me that I could have acquired the infection in many ways including rubbing the eye, someone sneezing or coughing around me. I also work at an auto shop where one of the guys is blind in one eye from an injury. Eye protection should be the first priority in protective gear. Make sure any safety glasses acquired have side protection and use goggles in dusty environments. Since most safety lenses are plastic and are easily scratched, make sure you get extra lenses. Sterile ophthalmic irrigation solutions (eye wash) should be included in first aid kits for rinsing the eyes if exposed to dust or chemicals. The eye wash solutions can be found in EMT. supply houses. One I am familiar with is Bound Tree Medical. They offer several sizes from 1?2 oz to 16 oz. I like the 4 oz size because it provides sufficient fluid for most situations and fits in most industrial first aid kits. – Bill N.

JWR Replies: Many thanks for raising this topic. Eye protection is crucial. Whenever anyone in my family shoots we always wear eye and ear protection. Ditto whenever we use a chainsaw. (BTW, I use a Stihl brand “forestry” helmet with built-in earmuffs and a full face mesh screen, although I’ve read that the Peltor brand may be superior.) We now store our workshop face goggles right on top of our bench grinder, where we can’t forget to use them. A friend of mine with a very nice photovoltaic power system does essentially the same thing in his battery box:: he stores a set of wrap-around goggles right next to his hydrometer. (This, BTW, is a good practice for all safety gear. Store it alongside your tools–otherwise it will be “out of sight, out of mind.” You won’t forget to wear you kevlar safety chaps if you store them draped across your chainsaw box.)

We don’t drink alcohol at the Rawles Ranch but we keep a shot glass handy, since they make an ideal “eye cup” for irrigating foreign matter out of an eye. And now that you’ve mentioned it, I now plan to add a mini-eye-wash station to our workshop. That is cheap insurance.

Parenthetically, many years ago a friend of our family was doing some tree pruning in his yard and had a pine bough whip across his face. This deeply scratched the cornea of his right and caused him years of trouble and some expensive medical bills. Simply wearing goggles would have prevented this mishap.

Letter Re: Who Can Supply Sturdy Headsets for FRS Transceivers?

Mr. Rawles;
I am having problems finding reliable headsets for Family Radio Service (FRS) radios. Do you know anyone I can ship mine to and have something made that will last and work?
I got Radio Shack models and the headsets do not last a year of steady use. I got one model you cannot get headsets for anymore.
The headsets cost $25 each and having to continuing purchase them is getting ridiculous. Even with Radio Shack warranties, if the SHTF you cannot run to them to get replacements.
I am willing to pay for quality headsets to last in a SHTF situation.
I just purchased some replacement FRS radios for the ones that I cannot get headsets for and they have a feature to scan and find the channels being broadcast on.
Do you have any experience with these? Does it include the silent or side band features? Does this mean OPSEC is even less (more at risk) if using them in the field?
Sure would appreciate the help. – Ron A. in Ohio

JWR Replies: My general advice it to buy yourself a sturdy $60 or $70 headset once, instead of four or five flimsy $25 headsets in succession to obtain the same service life. One good vendor that has been highly recommended is CustomEarpiece.com

OBTW, I prefer MURS band transceivers, such as those sold by $49 MURS Radios. MURS band radios have much better range and security than FRS radios. (It is more secure because it is a little known band.) The FRS occupied frequency scanning feature that you mentioned is likely become more common in coming years, making the pitiful security of the FRS band even worse.
