Card 1 — Water Availability & Purification
Why It Matters: Water becomes scarce fast in grid failures; contaminated water kills and dehydration incapacitates within days.
Store at least 1 gallon per person per day (2–3 is safer when factoring cooking and hygiene). For 30–90+ day readiness, acquire large-capacity containers and rotate them. Develop renewable sources: rain catchment, wells, streams, and snowmelt. Use multi-stage purification (mechanical filters, boiling, chemical treatment, charcoal/activated carbon where appropriate).
- Store 30–90 days of potable water; secure larger tanks for long-term.
- Install rain catchment with first-flush diverters and debris screens.
- Have portable filters (Sawyer, Katadyn, Berkey) + purification tablets.
- Keep metal containers for boiling; learn solar disinfection methods.
Card 2 — Food Storage & Calorie Strategy
Why It Matters: Stores empty quickly and supply chains fail; calories and nutrition directly affect physical function.
Short-term preps (30–60 days) are a baseline; aim for 6–12 months or more for true resilience. Prioritize long-shelf-life staples (rice, beans, oats, freeze-dried meals, canned proteins) and high-calorie items (oils, nuts). Rotate inventory and combine storage with production—gardening, foraging, hunting, small livestock.
- Stock a 6–12 month mix of shelf-stable foods.
- Use Mylar bags + oxygen absorbers for grains; rotate FIFO.
- Learn preservation: canning, drying, fermenting, smoking.
- Plan gardening and seed storage (heirloom seeds recommended).
Card 3 — Shelter, Home Safety & Environmental Protection
Why It Matters: Exposure kills faster than starvation; shelter must retain heat, cool, and protect from weather and threats.
Ensure your primary shelter (home) is structurally sound, insulated, and securable. Prepare portable shelters (tents, tarps, bivy sacks) for evacuation. Learn primitive shelter-building skills and maintenance for alternative heating/cooling methods.
- Weatherproof and insulate living spaces; fix leaks and drafts.
- Store tarps, bivies, emergency blankets, and tent repair kits.
- Know safe indoor heating methods (woodstoves) and ventilation.
- Practice rapid shelter deployment and repair techniques.
Card 4 — Security, Defense & Home Fortification
Why It Matters: In breakdown scenarios, law enforcement response is delayed; prepared households are targets.
Design layered defenses: perimeter (lighting, fences), immediate entry points (reinforced doors/windows), and safe rooms. Security is not just hardware—train in situational awareness, de-escalation, and collective defense with trusted neighbors.
- Reinforce doors, frames, and windows; add deadbolts and bars where legal.
- Install motion lighting and passive deterrents (fencing, natural barriers).
- Create community watch protocols and shared alert systems.
- Train with defensive tools appropriate to your law and skill level.
Card 5 — Fire, Heat & Fuel Management
Why It Matters: Fire provides warmth, cooking, sterilization, light, and morale when power is lost.
