Skills, Resilience & Life Mastery
Preparedness & Survival
- Survival & PreparednessThe starting point for GoldBlock's preparedness cluster. It routes you to water, food, shelter and heat, medical, and tools in the order the official planning guides use, with the planning figures each section rests on.
- Water Preparedness: Safe Water for Your Household in Any DisruptionA complete water system for a household: know how much you need, store it, know how to make doubtful water safe, choose filters on evidence, and plan for your own source and for failures of the city, the grid or the weather.
- Food Preparedness: Feeding Your Family Through Any DisruptionA complete food system for a household: know what each person needs, eat from a pantry you rotate, grow and preserve what you can, and keep emergency food as the last backup.
- Shelter, Heat & PowerShelter, heat and power decide whether a disruption stays manageable or turns into real risk: how to keep a home safe from carbon monoxide and fire, hold a safe temperature, keep essential things powered, stay lit and informed, and know when to go somewhere else.
- Backup Power for Vital Loads: Freezer, Well Pump, Medical DevicesHow to size and safely run backup power for the few things that matter most in an outage: refrigerators and freezers, a well pump, heat and medical devices, using generators or batteries.
- Medical & First AidMedical preparedness at home: the categories of problems people prepare for, the warning signs that mean call 911, and how a first aid kit is stored and rotated. Educational, not medical advice.
Water Preparedness
- Water Needs: How Much Water Your Household Really NeedsHow much water to store for each person, how many days to plan for, who needs more, how babies and animals change the math, and the warning signs of not getting enough.
- Storing Water at Home: Containers, Rotation and the Water Already in Your HouseHow to keep a safe emergency water supply at home: which containers to use and avoid, how to clean, fill and label them, where to keep them, when to replace the water, and the water your house already holds.
- Making Water Safe to Drink: Boil, Disinfect or FilterHow to make doubtful water safe in an emergency: which method handles which problem, how to boil and disinfect water using the official CDC and EPA procedures, what filters, UV and distillation can and cannot do, and the water no home method can fix.
- Water Filter Ratings and Certifications: How to Read a Filter BoxWhat a water filter's claims really mean: filter versus purifier, log reduction, the NSF/ANSI standard numbers, certified versus tested to, micron ratings, how to check a listing yourself, and the marketing red flags.
- Emergency Water Filters Compared: Straws, Pumps, Bottles, Gravity Filters and TabletsEighteen emergency water filters and purifiers, plus three treatment tablets, compared on what matters: what each maker says it removes, which certifications we could actually find, rated capacity, care in the cold, and cost per gallon.
Food Preparedness
