What is the Rule of 3s in Prepping?: Essential Survival Guide

The Rule of Threes is a basic guideline in prepping that emphasizes the priorities for survival during an emergency event. This rule can help you plan and prepare for unexpected situations, focusing on the most essential aspects of sustenance and safety. The Rule of Threes outlines the following key needs:

  1. Air: You can survive about 3 minutes without air or oxygen.
  2. Shelter: You can survive approximately 3 hours without shelter in extreme heat or extreme cold.
  3. Water: You can survive around 3 days without water.
  4. Food: You can survive nearly 3 weeks without food.

Air and Oxygen: The first priority in the Rule of Threes is to ensure you have access to clean, breathable air. In case of an emergency where air quality is compromised, you should be prepared to perform basic first aid techniques such as CPR or the Heimlich maneuver, and possess a gas mask or a similar breathing apparatus.

Shelter: Shelter is crucial for protecting yourself from harsh weather conditions and maintaining body temperature. Your home serves as the primary shelter, but you should also consider having alternative options such as tents or tarps in case your home is compromised. Furthermore, fire is essential not only for keeping warm but also for cooking food and purifying water.

Water: Dehydration can be a serious problem in emergency situations, so securing a clean water source is a top priority. Store a sufficient amount of water, and be familiar with ways to purify water if needed, such as using a Lifestraw, boiling, or chemical treatments.

Food: While not having food can be incredibly uncomfortable, it's actually less of an immediate concern than air, shelter, or water. Nevertheless, you should have a stockpile of food with long shelf lives, such as canned goods, freeze-dried survival meals, and preserved items. Knowledge of cooking techniques and skills in foraging can also be valuable if your food storage runs low.

What is the Rule of 3s in Prepping

Three Minutes Without Air

Ensuring a continuous supply of breathable air is crucial in any prepping situation. Oxygen is a basic necessity, and as the rule of 3s in prepping states, you can survive only 3 minutes without air. In this section, we'll discuss strategies to help maintain good air quality in various situations.

Air quality in shelters: When creating your shelter, ensure proper ventilation to avoid built-up carbon dioxide and other harmful gases. Design your shelter with vents or air exchange systems, and if it's sealed too tightly, install a carbon dioxide detector or air purifier to maintain clean air.

Gas masks and filters: Investing in a good-quality gas mask is essential for preppers. They can protect you from inhaling harmful substances, such as smoke, dust, or chemical fumes. Make sure to choose the right mask based on the potential threats you may encounter. Maintain your mask properly, replacing the filters as needed, and store it securely with your other prepping supplies.

CPR and Heimlich maneuver: Familiarize yourself with first aid techniques like CPR (Cardiopulmonary Resuscitation) and the Heimlich maneuver, which can save lives in situations with restricted airways. Take a certified CPR course and regularly refresh your skills, while also encouraging your family members to learn these life-saving techniques.

Power outages: During a power outage, maintaining air quality is essential. Avoid using alternative heating sources such as kerosene heaters or charcoal burners indoors, as they produce carbon monoxide, a dangerous odorless gas. Open windows and doors periodically to allow for proper ventilation.

Three Hours Without Shelter

The second essential aspect is finding shelter within three hours. This duration emphasizes the importance of protecting yourself from various environmental factors that can impact your well-being.

When you're faced with harsh weather conditions, such as extreme heat or extreme cold, having a shelter can make all the difference in ensuring your safety. A shelter creates a barrier between you and the elements, regulating your body temperature and preventing potential health hazards like frostbite or heatstroke.

While at home, you can easily transform parts of your living space into a shelter. However, during emergencies or outdoor adventures, you'll need to rely on temporary structures like tents or tarps for protection. Let's look at some common, everyday items you can use to create temporary shelters:

  • Tarp: A versatile waterproof material that can be pitched with some cordage and stakes to create a simple, effective shelter.
  • Poncho: If you have a poncho handy, you can easily convert it into a makeshift tent by tying the hood to a branch or a nearby structure.
  • Emergency blankets: Mylar emergency blankets can be used to insulate your body heat, or they can be strung up to create a windbreak or makeshift rain cover.

Remember that fire can also serve as a shelter, at least partially. Building a fire close to your temporary shelter can provide warmth, helping you maintain your body temperature, and also keep potential predators at bay. However, be cautious and mindful of your surroundings while starting a fire, as not to cause unintended harm to the environment or yourself.

When prepping for potential emergency situations, prioritize establishing reliable shelter options and maintaining a well-stocked supply of necessary items like tarps, tents, and emergency blankets. In doing so, you'll be adequately prepared to face whatever Mother Nature throws at you, keeping yourself safe and protected against various environmental elements.

Three Days Without Water

In the context of prepping, it is essential to recognize the importance of water for human survival. As per the survival rule of 3s, you can survive only three days without water. This vital resource serves numerous purposes, and in your prepping journey, ensuring a sufficient supply of clean, drinkable water should be a priority.

When preparing for emergencies, store water in a cool, dark, and dry location. It's advisable to store at least one gallon of water per person per day, covering a minimum of three days. However, prepping for longer durations is always beneficial. To ensure your stored water remains safe and fresh, use food-grade storage containers, and remember to replace them at least once every six months.

Another crucial aspect of prepping is learning how to purify water from various sources. Some natural sources, such as lakes and rivers, may contain harmful bacteria and contaminants. Familiarize yourself with different water purification methods to keep your water safe for consumption.

There are numerous ways to purify water:

  1. Boiling: This is an effective method to eliminate most pathogens. Simply bring the water to a rolling boil for at least three minutes, then allow it to cool before consuming.
  2. Chemical purification: You can use either chlorine or iodine tablets to purify water. Follow the manufacturer's instructions for correct usage.
  3. Filtration: Portable water filters like the LifeStraw can remove bacteria and protozoa from the water effectively. This compact device is perfect for preppers, as it doesn't require any power source, and you can easily carry it in your bug-out bag.
  4. Distillation: This method involves boiling water and collecting its vapor in a clean container. This process eliminates most impurities, including bacteria, viruses, and chemicals.

Three Weeks Without Food

When preparing for a survival situation, it's crucial to understand the role of food in maintaining your health and energy levels. The rule of 3s emphasizes that you can survive up to three weeks without food. However, as a prepper, your focus should be on ensuring a balanced and nutritionally rich food supply to sustain you during emergencies.

To begin with, consider the importance of food storage in your prepping strategy. Organize your supplies to ensure you have a variety of non-perishable, high-quality food items stored safely. Long-lasting options include canned goods, rice, beans, and pasta. Additionally, make sure to regularly rotate your food stock to prevent spoilage and maintain the effectiveness of your food storage system.

Next, give some thought to incorporating survival food into your preparedness plan. Opt for freeze-dried survival food, which has a long shelf life and can be easily rehydrated when needed. These convenient and portable meals come in a range of options, providing you with a variety of flavors and essential nutrients to maintain your health during a crisis.

Another essential aspect to consider is how you'll cook and prepare your food during an emergency. Ensure that you have alternative cooking methods in place, such as portable stoves, solar ovens, or camping cookware. Familiarize yourself with these methods and practice using them to guarantee smooth and efficient meal preparation when it truly matters.

Lastly, it's vital to account for all necessary food-related supplies in your prepping plan. Stock up on items like cooking utensils, can openers, reusable storage containers, and portable water filters for potable water access. These essential supplies will help you cook, store, and maintain your food supply, contributing to your overall well-being during survival situations.
