Potassium permanganate: The Most Useful Survival Chemical
When people think about survival tools, chemicals are usually not one of the first things that come to mind. Potassium permanganate should, though.
Also known as KMnO4, Condy’s Crystals and permanganate of potash, Potassium permanganate is a jack of all survival trades. When it comes to survival, the more you know, the more you can do with less. Like wilderness medicine, it also often becomes about improvising with less than ideal tools.
I first learned about the usefulness of this chemical while watching a Survivor Man episode titled Sonoran Desert. In the Sonoran Desert episode (Season 1 Episode 2), Les Stroud demonstrates how mixing Potassium permanganate and glycerin will start a chemical fire. Intrigued, I did some digging.
It turns out, this chemical not just useful for making fires. Here are the 7 best uses for Potassium permanganate:
Potassium permanganate will start a fire when mixed with a couple of different compounds. Glycerin is the most common, but antifreeze will also do the trick. Antifreeze seems to create a reaction that is a little more violent. Be very careful when using either. The reaction is not always immediate. It can take several seconds for the reaction to start a fire – let it be.
After gathering all the necessary fire tinder and large pieces of wood to keep your fire going, place a teaspoon of Potassium permanganate on a flat surface. Carefully add the same amount of Glycerine or Antifreeze evenly on top of your pile. Next, stand back a couple of feet and wait at the ready with your tinder.
Mix sugar in with the Glycerin before adding to your Condy’s Crystals, and you’ll get a decent signal smoke.
For water purification, its use is relatively straightforward. First, if there is any sediment in the water, strain it out. Then add 3 – 4 crystals per liter of water. Stir or shake for a few seconds then let sit for 2 hours. The water should be a light pink (a concentration of 1:10,000) – no darker.
Here are some proportions for killing the different nasty organisms that can find their way into water:
Just remember, as long as it is pink – it’s probably ok to drink.
To use as an antiseptic, anti-fungal treatment, or emergency snow signal, add crystals one by one until the solution turns purple. Shake and use to flush out a wound, soak a fungal infection, or to leave a message in the snow.
Don’t eat snow marked in yellow – just saying.
Ideally, Potassium permanganate should be stored in a nonreactive plastic bottle with a Teflon coated cap. Most plastic bottles and non-coated caps should be fine.
Potassium permanganate is not a perfect option for any of the above-listed purposes. If other more convention options are available – use them first. What it does do is offer another option should you find yourself with it as your only resource.
Potassium Permanganate Usage Warnings
Everything in life comes with a warning label, “Caution, this air compressor may cause bloating.“ Here are a couple things you should be warned about when it comes to playing with Potassium permanganate:

Here are some proportions for killing the different nasty organisms that can find their way into water:
- Bacteria require a minimum of 2.5mg per liter of water.
- Viruses require a minimum of 50mg (close to danger levels) per liter.

Potassium Permanganate Usage Warnings
Everything in life comes with a warning label, “Caution, this air compressor may cause bloating.“ Here are a couple things you should be warned about when it comes to playing with Potassium permanganate:
- It’s an aggressive oxidizer. It must be kept in a safe, non-reactive container.
- Potassium permanganate solutions mixed too strong can cause caustic burns!
- Potassium permanganate will dye just about anything it comes in contact with pink or purple.
