Subject: Homemade O2 absorbers ??
A question for those who know more than I about the chemistry of this. Watching a documentory on Military foods and storage methods, I saw a small package being added to the new bread ration. The woman explained that it was an O2 absorber and we all know what that is for.
Now.....this O2 absorber contained salt, iron, and another ingredient that I missed. The process of 'rust' involves the ozidation of the iron and will use the O2 in any surrounding atmosphere (or water, just slower). I understand that some moisture is also needed for the process.
Question : If I mix common table salt and iron powder in a small container and arrange that it can interact with outside air, will I have not made an O2 absorber ? What is wrong with this idea ?
I have a supply source of fresh iron powder and salt is $0.30 a pound at the store.
I will do some simple experiments with this idea used in sealed containers with a vacuum gauge attached. This should tell me if it works. The question I have is: "Is there any reason this would not be safe to use in stored food if reasonable effort is made to keep the ingredients out of contact with the food ?"
I wish to store grain in large (50 gallon)containers and I want to deplete the O2 in these containers. I'm looking at this as a cost effective way to do it.
Regards, Art Welling

Subject: Keep Careful
Keep careful records of the experiment and if you find some thing that works let me know. Be careful you might implode a few barrels to get it right.

Subject: Records ? We don't need no stinkin records !
To paraphrase a mel brooks movie I love (g)
I am not a scientist, but I have done considerable precision reloading of small arms ammunition. I have learned how to keep records.
Implode a barrel ? By losing aprox 20% of the internal atmosphere's volume ? Figure that a well packed plastic drum (50 gallons) of corn might contain by volume 25% air. That would be approx 2.5 gallons of O2 removed if we removed 100% of the O2, or 5% of the interior volume. I thinking pulling 5% out of a 50 gallon plastic drum would not be likely to implode it. Especially if it's well packed and can use the corn itself for support. What I might worry about is stress cracks in the plastic letting air in to replace the absorbed O2.

Subject: Intercranial Gastritis
Intercranial Gastritis commonly known as a brain fart.
I should have have figured that out before I spoke. It would appear that imploding would be impossible.

Subject: Home made oxy absorbers
Alan T. Hagan, the keeper of the Mis.Survival Food Storage FAQs at one time experimented quite a bit with trying to make oxygen absorbers. The last I heard from him on this subject, he was right in the thick of it all. His main setback was, try as he could, he couldn't get the chemical reaction to take place quickly enough. Instead of it taking hours like a normal oxy absorber, it was taking weeks/months/years. I never heard back from him if he hit on the solution.

It seems from my perspective that it should be safe. I'd love to learn how to do this, if you can get it figured out.

Subject: Making your own...
I still don't know how this is done, but thought the following might be of interest to those of you who are trying to figure this out.
Last week I got some of our hand warmers. Removing them from their package started them working. This made me wonder if they worked by absorbing oxygen. So I took the now warm packet and threw it into a canning jar and screwed on the lid. Sure enough, it created a vacuum. Then I opened the lid and put a lit match into the bottle. The match was instantly extinguished. Interestingly enough, they list the ingredients on the package...
"Contents: Iron powder, water, salt, activated charcoal, cellulose."
Now, to put it together will take some experimenting.

Subject: Caution a Fire Chief speaks
I have been thinking about this and I must add a word of caution. O2 absorbers produce heat and comsume 02, this is indicative of combustion/oxidation. Exercise extreme caution when experimenting in chemistry. The combustion/oxidation is a slow process, but could speed up if the proportions are increased and out of balance. I recommend that anyone experimenting use common precautions to develop the proportions necessary. DO NOT MIX MORE THAN YOU WANT TO BLOW UP IN YOUR FACE, HAVE A FIRE EXTINGUISHER HANDY, WEAR GLOVES AND GOGGLES. Keep records, measure accurately, work with small quantities.
I have not worked with these substances, but realized from Al's post that they can be and are used in arson. Please don't ask me how, I won't say. I will say that I do not think they will flash easy, but they can and will cause a slow smoldering fire that eventually will, if mixed in the wrong proportions.

Subject: checking for oxygen levels!!!!!
From A.Hagans (think that's his name) storage FAQ>>>> When I think it's full I'll hold a lit match just above the bag in the air that is escaping from it. If it snuffs right out then I let it run for about a minute longer to flush out more of any remaining oxygen and remove the wand.
leave me a post here if you want the entire FAQ. I have it in txt version here. It is VERY conclusive...home nitro packing/dry ice method/oxygen absorbers/decisicants/fossil stabilizers, etc.
Also, this looks like an affordable solution that I am going to purchase.http://www.stortite.com/

Subject: oxy absorbers
I can understand wanting to make your own, but they are very reasonably priced. With so much for us to do, wouldn't it be better just to purchase them and have them ready to use when you are. They come in a resealable packet, so you don't have to use them all at once. Last time I used some at the LDS cannery they were 8 cents each. even if thats whole sale, half price, then retail full price wouldn't be more that 15 cents each. Making them seems a lot of trouble for a few cents. and you have to go a long way to find someone cheaper than me.

Subject: Absorbing O2 with dry ice
The Jim McKeever book, Preparing For Emergencies describes the method of packing your own grains, etc. by using dry ice in the bottom of the bucket. The CO2 forces the O2 out.....
He also descibes storing items in plastic bags inside of plastic buckets then placing a smaller bag of rock salt on top to absorb moisture before sealing.
