SHTF Survival Guide: An Overview of SHTF
ZacharyWilliamEvidence-based preparedness for families, homeowners, and outdoorspeople. Curated from public‑sector guidance and field-tested practices.

What Is “SHTF”?
“SHTF” (“stuff hits the fan”) is community shorthand for high‑impact disruptions—storms, wildfires, grid failures, cyber incidents, earthquakes, or civil emergencies—that strain normal services. A good SHTF plan turns panic into a checklist: assess hazards, meet basic needs, and stabilize your household until help and infrastructure return.
Common SHTF Triggers & Risk Mapping

Natural hazards
Hurricanes, wildfires, floods, winter storms, heat waves, earthquakes. Expect power/water outages, blocked roads, medical access delays.
Infrastructure failures
Regional blackouts, cyberattacks on utilities, water main breaks, fuel shortages. Plan for at‑home sheltering and limited communications.
Local emergencies
House fires, chemical spills, neighborhood evacuations. Build go‑bags and rendezvous points in advance.
Survival Priorities: Safety, Water, Shelter, Power, Comms
- Personal safety: First‑aid, situational awareness, and avoiding secondary hazards (downed lines, flooded roads).
- Water: Store enough for drinking and sanitation; add treatment options.
- Shelter & warmth: Weather‑appropriate clothing/bedding, tarps, tools, and safe heat sources.
- Power: Keep lights, medical devices, and comms alive with battery systems that can recharge off grid.
- Communications: Family plan, radios, contact lists, and critical documents.
Your 72‑Hour Kit (and 2‑Week Upgrade)
Core supplies (per household)
- Water: at least 1 gallon per person per day (72 hours minimum; 2‑week goal).
- Non‑perishable food + manual can opener.
- Flashlights/headlamps + spare batteries and/or crank light.
- Battery or crank radio; phone power banks.
- First‑aid kit; prescription and over‑the‑counter meds.
- Hygiene items; sturdy trash bags; work gloves; dust masks.
- Copies of vital documents; small bills; spare keys.
- Multi‑tool; duct tape; waterproof matches; fire extinguisher.
2‑Week upgrade
- Expanded water (or larger containers) and treatment chemicals/filters.
- Extra fuel sources that are safe for indoor use (battery/solar).
- Comfort foods, games, and child/pet‑specific needs.
- Redundant comms (GMRS/FRS/ham handhelds).
Water: Storage, Treatment, and Safety
Plan for drinking and sanitation. Store sealed containers in a cool, dark place. Keep unscented household bleach on hand (5–9% sodium hypochlorite) for emergency disinfection. Add filtration as a secondary method.
Topic | Quick guidance |
---|---|
Minimum storage | ≥1 gallon per person per day for 3 days; aim for 2 weeks. |
Treatment backup | Boil when possible; otherwise use bleach drops per guidance; use filters rated for microbes. |
Special cases | Increase for hot climates, pregnancy, illness, and pets. |
Power Continuity: Choosing a Portable Power Station
A LiFePO₄‑based portable power station offers safe indoor power, long cycle life, and fast recharge from AC, vehicle, or solar. Match the inverter output to your critical loads (e.g., CPAP, modem/router, lights, laptop, small fridge) and prefer units with UPS capability for seamless switchover during outages.

- Battery chemistry: LiFePO₄ for safety and longevity.
- Capacity (Wh): Determines runtime—size for 24–48 hours of essentials.
- AC output (W): Continuous rating ≥ your peak simultaneous load.
- Recharge options: Wall, car, and MPPT solar input to extend autonomy.
- Noise & indoor use: Silent operation is ideal for night and apartment use.
Food Storage & Safe Emergency Cooking
Pantry planning
- 3–14 days of ready‑to‑eat foods (canned beans/meats, soups, nut butters, oats, rice, shelf‑stable milk).
- Include comfort foods to keep morale up.
- Rotate stock (first‑in, first‑out); label dates.
Indoor‑safe cooking
- Use indoor‑safe options (electric hot plate on battery power, butane stove only if rated for indoor use and with ventilation).
- Never use charcoal/propane appliances indoors due to carbon monoxide risk.
- Have manual can openers and heat‑and‑eat meals.
Medical & First Aid
Build a robust kit and keep skills current. Seek certified training (basic first aid/CPR, Stop the Bleed) and follow medical guidance from professionals.
Essentials
- Personal meds (7–14 days), copies of prescriptions, and a med list.
- Wound care: assorted bandages, sterile gauze, tape, antiseptic, gloves.
- Over‑the‑counter: pain/fever reducer, antihistamine, antidiarrheal, oral rehydration salts.
- Thermometer, tweezers, trauma shears.
Special equipment
- Device power plans for CPAP, insulin refrigeration, mobility aids.
- Backup glasses/contacts and hygiene solutions.
Medical advice in emergencies should come from licensed professionals and official guidance. This guide is educational and not a substitute for care.
Hygiene, Sanitation & Waste
- Waterless hygiene: hand sanitizer, wet wipes, biodegradable soap.
- Toilet backup: heavy‑duty bags, absorbent material/gel, and a sealable container; store away from living areas until municipal service resumes.
- Trash management: thick bags, ties, and separation of food waste; keep lids closed to deter pests.
Communications & Information
- NOAA weather radio or all‑hazards radio; spare batteries or crank.
- Handheld FRS/GMRS radios for local coordination; learn channel discipline.
- Keep a printed phone tree and out‑of‑area contact.
- Offline maps (paper) and key numbers written down.
Home Safety & Non‑Violent Security
- Light the exterior at night (battery/solar lights) and keep doors/windows locked.
- Work with neighbors: share updates, check on vulnerable residents.
- Store fuels and chemicals safely; install and test smoke/CO alarms.
- Document valuables and keep insurance info in your go‑folder.
Pets, Seniors & Accessibility
Pets
- Food/water for 3–14 days, carrier, leash, meds, vaccination records.
- Pet‑safe sanitation supplies and waste bags.
Older adults & disabilities
- Backup power for medical devices; labeled med schedules.
- Mobility and transport plan with helpers and alternates.
Power Runtime Planner (Examples)
Estimate runtime by dividing battery capacity (Wh) by device consumption (W), then apply an efficiency factor (~0.85 for AC loads).
Device | Typical draw | Estimated runtime |
---|---|---|
Wi‑Fi router + modem | 20W | ~50 hours |
CPAP (no humidifier) | 40W | ~25 hours |
LED light (10W) ×4 | 40W | ~25 hours |
Laptop charging | 60W | ~17 hours |
Mini‑fridge (duty cycle) | 60W avg | ~17 hours |
Actual runtime varies by device efficiency, inverter losses, temperature, and usage patterns.
Training, Maintenance & Drills
- Test your power station monthly; keep batteries between 30–80% when stored per manufacturer guidance.
- Run a 15‑minute evacuation drill twice a year and a 24‑hour at‑home outage drill annually.
- Update kits every season; check expiration dates.

Family Communication & Evacuation Plan
- Agree on two meet‑up points: one near home, one outside your neighborhood.
- Create a wallet card with emergency contacts and an out‑of‑area check‑in person.
- Know how you’ll receive alerts (e.g., Wireless Emergency Alerts, NOAA weather radio).
- Map primary and alternate evacuation routes; keep a printed map.
- Practice: run a 15‑minute drill twice a year (Ctrl/Cmd+P to print your plan).
FAQ
How much water should I store?
Start with at least 1 gallon per person per day for 3 days, and build toward a 2‑week supply. Increase for heat, pregnancy, illness, and pets.
Is a gas generator better than a battery?
Gas generators provide higher surge power but are loud, emit fumes, and must run outdoors—often not ideal during storms or at night. Battery stations are silent, safe indoors, and can recharge via solar.
What devices should be first on backup power?
Lights, phone/modem, medical devices (e.g., CPAP), radios, and a small fridge or critical chargers. Prioritize safety and communication.
