Prioritize with the Rule of 3’s

The Rule of 3’s is a method for prioritizing your basic survival needs.  It provides a relative magnitude to the importance of 4 key elements of human survival: Air, Shelter, Water, and Food.  We’re going to walk through each element to help you understand how you prioritize them in various emergency circumstances.

Air – 3 Minutes

Our bodies can’t function if deprived of oxygen.  If you fall underwater you have about 3 minutes to get up for air, and rescuers have about 3 minutes to help you out before potential long term damage occurs.  In a fire, smoke will make it difficult to breathe.  In addition to the smoke that you can see, carbon monoxide can make it hard to breathe and you can’t see it or smell it.  Making sure you have working smoke detectors and carbon monoxide detectors are critical for giving you a chance to escape.

Shelter – 3 Hours

What would have happened if you had been caught out in the elements?  Humans are not designed to live in sub-freezing temperatures for any period of time without some form of shelter.  In a disaster, you want to stay dry and stay at a moderate temperature (not too hot and not too cold).

Water – 3 Days

Food – 3 Weeks

This will look very different depending on your location.  You will likely have a large stockpile of food at your house.  Make sure you have some food in your vehicle and in your everyday carry (we’ll spend more time going through vehicle and everyday carry setups in an upcoming article) so that you can sustain yourself until you can get home.  I always make sure I have a box of protein bars in each of our vehicles and I always have a couple of bars in my everyday carry bag (laptop bag).  That may not seem like a lot of food, but in an emergency, you won’t be eating on a normal schedule.  Your goal is to ration until you make it to “safety”, not to see how fast you can eat your bars.

As you continue through your Preparedness Journey, utilize the Rule of 3’s to help you prioritize.  It can help you prioritize which skills to learn.  It can help you prioritize which gear to purchase first and which gear to invest in more.  Most importantly, it can help you prioritize your emergency plan to keep you and your family safe.
