Survival - the Rule of 3s
« on: July 26, 2016, 04:15:10 PM »
When I was in the military overseas I was fortunate to go on a few bush-survival courses and of the things which have stuck with me over the years, a big one is what they called the Rule of 3s.

In short, it's a mnemonic aid to help you prioritize your needs and basically it means that, in extreme conditions, you can survive for:

* 3 minutes without Air.
* 3 hours without Shelter.
* 3 days without Water.
* 3 weeks without Food.

Some folks add "3 months without Hope" to that list, which is grim but probably quite true.

Not much point in trying to find water if you're on the verge of freezing to death, you know? It's a pretty easy sequence to remember - so if you're ever stuck, arrange your priorities accordingly.
There's nothing quite like the offer of 230 grains to a man's chest to remind him of his manners.

You can survive 3 hours without shelter?

I'm not sure what it is you're asking.

You know what, my bad, I failed to see the caveat "in extreme conditions." Disregard.

Good post AndyC. Yes in the extreme situations these are the rule of thumb inspiring goals to remember. Keeping your head and targeting a time goal.

Thanks - it's nothing extraordinary or magic, it's just a quick guide to keep in mind when trying to figure out what you need to do next.

Assuming one has the relevant skills to procure/make shelter, fire, clean water, etc - yes

3 minutes without air?  I would think 60 seconds is more than most people could do, let alone 3 minutes in "extreme" conditions of rigorous physical activity...

The rest seem very plausible for me, though.  It's all contextual, though - If it's summer in a temperate zone, I'm gonna worry about water before I worry about shelter, but if it's cold and nasty?  Definitely shelter.

To the above mnemonic I might add: 3 seconds without a weapon.
At least in certain situations.

Three is Two, Two is One and ONE is “NONE”

This is a concept used by many in the military, hunters, campers and by others; when having just one important item may lead to serious trouble or great inconvenience. We all know things we rely upon suddenly break, become lost or where we need to loan to another person. The only question is, how many backups should one have! When you only have one, it can break, become lost etc. and then you can be in very serious trouble. Thus the need for two or more of all critical items.

Examples are a pair of eye glass lost or damaged during a vacation down south, a flashlight that fails thirty minutes into a hydro failure, a compass that falls out of your shirt pocket into the lake

Medicine; While the government recommends having three days of emergency supplies with you at home etc. we believe that for items such as medicine, it should be at least 10 days. Who wants to run out of medicine on day four!

Flashlights and of course the very best batteries; I like to have three with me in my kit.

Eye-wear; Minimum of two pairs

Knives; Small pocket knife or multi tool and two larger knives for cutting of firewood, branches for shelters etc.

Matches; when hiking etc., this is where you want three waterproof match containers. One in your pants pocket, one in your pack and maybe one in a shirt pocket. Pant or shirt pockets rip and if you only have two, you now only have one in your pack. If you fall in the water or down a hill, your pack will sink to the bottom or may have contents spill out.

Compass or GPS; For any serious camping or survival situation, I would recommend a minimum of three means of navigation. Minimum of one compass and two GPS units or the reverse of that depending on your preference. Remember, a GPS units need power as where a compass does not.
Socks; Socks are extremely important to one’s survival. If your feet are cold or wet, you may develop serious blisters, suffer from frostbite or simply be miserable. So for a day hike you want at least one spare pair to the ones you are wearing.

Charging cables and backup battery for smart devices; You want to be able to communicate or receive emergency updates from media. I would prefer to have three charging cables. You also want the means to charge smart devices and any GPS! So have at least two solar chargers and one or two backup battery sources (UPS) to store power collected when the sun is out. Note; all UPS units should be fully charged before leaving and if in an emergency pack, car or home; charged up two or three times a year, so you know they are always ready for use.

Food; Out for a day’s hike, then you want minimum an extra days’ worth of food and water. You may become lost, injured or delayed due to a storm. If in very isolated areas or where the weather can change fast, then three days’ worth of food and water is the “bare bones” minimum. Datrex food bars are light, do not need water or cooking and are a decent tasting emergency ration.
