Supplies for Extended Shelter-in-Place During Conflict

What to stockpile and how to manage water, food, medical supplies, power, and sanitation for two or more weeks of shelter-in-place during armed conflict.

Shelter-in-place during active armed conflict is categorically different from sheltering during a hurricane or power outage. The duration is unpredictable — days, weeks, or months. Access to resupply is cut off. Medical services are unavailable. The consequences of running out of water, food, or critical medication are not inconvenience but injury, illness, and death.

Preparing a supply stock before you need it is an act of survival planning. This guide provides the full detail you need to prepare, manage, and prioritise supplies for extended shelter-in-place in a conflict environment.

Water: The Critical Priority

No survival supply matters more than water. Dehydration begins affecting cognitive function within 24 hours and becomes life-threatening within 3–5 days. In conflict environments where utility services are frequently disrupted and water sources may be contaminated or inaccessible, stored water is your foundation.

Minimum water requirements:

PurposeQuantity per Person per Day
Drinking2 litres minimum (3–4 litres in heat)
Basic food preparation1 litre
Minimal sanitation and hygiene1 litre
Survival minimum total3 litres
Comfortable minimum5 litres
Recommended planning figure1 US gallon (3.8 litres)

For a two-week shelter, plan for 1 gallon (3.8L) per person per day as your planning figure. For a family of four over 14 days, this is 212 litres — approximately 55 US gallons or eleven 20-litre containers.

Storage:

  • Use food-grade containers with tight-fitting, sealable lids
  • Keep water in a cool, dark location; heat and light degrade storage life and promote bacterial growth
  • Commercially sealed water is safe for 2+ years; home-stored tap water should be rotated every 6 months
  • Label each container with the fill date

Emergency water collection:

  • Fill all available containers (bathtubs, buckets, pots) at the first sign that conflict or utility disruption is approaching
  • Rainwater can be collected from roof runoff — store in covered containers to prevent contamination
  • All non-commercially-sealed water should be treated before drinking (see Water Purification guide)

⚠️ Never assume the water will stay on. In conflict, utility infrastructure is targeted deliberately. Fill every container you have the moment you judge that fighting is approaching your area.

Food: Calorie-Dense, No-Cook Options

Food planning for extended shelter must account for two realities: cooking may be unsafe or impossible (fuel unavailability, cooking smells, smoke signature), and access to markets will be cut off.

Caloric requirements: An average adult requires 1,800–2,500 calories per day. Children and pregnant or nursing women have different requirements. In a sedentary shelter situation, caloric needs are lower, but cold, stress, and physical activity in the shelter increase them.

Best foods for conflict shelter:

Food TypeCaloric DensityStorage LifeNotes
Hard biscuits / crackers400–500 kcal/100g12–24 monthsNo cooking required; high carbohydrate
Nuts (almonds, peanuts, walnuts)500–600 kcal/100g12+ months in sealed containerHigh fat and protein; no preparation
Dried legumes (lentils, beans)300–350 kcal/100g dry2–5 yearsRequire cooking; versatile
Rice360 kcal/100g dry2–5 yearsRequires cooking and water
Canned protein (tuna, sardines, beans, lentils)100–200 kcal/100g3–5 yearsReady to eat cold; high nutrition
Peanut butter580–600 kcal/100g12–18 months openedNo cooking; high calorie density
Dried fruit250–350 kcal/100g12–24 monthsVitamins; no cooking
Energy bars350–500 kcal/bar12–24 monthsCompact; expensive
Cooking oil (olive, sunflower)900 kcal/100g12–24 monthsCalorie supplement for cooked food

No-cook planning: If cooking is not possible, your stock must be entirely no-cook. Prioritise biscuits, crackers, nuts, peanut butter, canned ready-to-eat foods, dried fruit, and energy bars. A typical day with no-cook food might provide 1,500–1,800 calories per person.

Cooking safety considerations: Cooking produces smells that can travel considerable distances and attract attention. During periods of heightened risk, cook with windows sealed and consider timing cooking to lower-risk periods (mid-morning when armed patrols are typically less active). Use small-flame cooking and avoid frying — frying produces more smell than boiling or steaming.

Medical Supplies for Conflict Wounds

Conflict shelters require medical supplies that go beyond a standard first aid kit. The most common causes of civilian injury in conflict — blast, shrapnel, and ballistic wounds — require specific interventions.

Wound care essentials:

  • Combat Application Tourniquet (CAT) or improvised tourniquet materials — extremity haemorrhage (arm, leg bleeding) is the most preventable cause of death from conflict wounds; know how to apply
  • Haemostatic dressings (QuikClot, Celox, or Combat Gauze) — for wounds where tourniquet is not applicable (junctional wounds at groin, armpit, neck)
  • Israeli bandages (emergency pressure dressings) — large, absorbent wound dressings with integrated pressure application
  • Chest seals (vented) — for penetrating chest wounds that create open pneumothorax
  • Sterile gauze and bandages — large quantities; wound care in shelter will extend for days
  • Medical tape — multiple rolls; used for everything
  • Antiseptic solution (iodine, chlorhexidine) — infection prevention is critical when access to antibiotics is limited
  • Oral antibiotics (amoxicillin, doxycycline) — if obtainable; wounds in unsanitary conditions have very high infection risk
  • Pain relief (ibuprofen, paracetamol) — adequate quantity for multi-week use

Prescription medications: If anyone in your shelter group takes regular medication, the most important preparation you can make is to stockpile 30–60 days' supply before a crisis peaks. This is especially critical for:

  • Insulin and diabetic supplies (insulin has temperature requirements — store below 25°C and away from freezing)
  • Blood pressure medications (abrupt cessation can cause hypertensive crisis)
  • Anti-seizure medications (abrupt cessation can trigger breakthrough seizures)
  • Mental health medications (many cause withdrawal symptoms on abrupt cessation)
  • Asthma inhalers (both reliever and preventer)

Consult with a healthcare provider before the crisis to understand the safety of stockpiling and, where applicable, how to manage gradual dose reduction if supply runs out.

Sanitation Without Running Water

Sanitation failure causes disease. In confined shelter with multiple people over days or weeks, poor sanitation leads to diarrhoeal illness, infection spread, and rapidly declining group health.

Toilet solutions:

  • Use existing flush toilets as long as water pressure allows; fill cisterns from stored water when pressure drops
  • When stored water must be conserved: use a bucket with a tight-fitting lid as a toilet; add a small amount of disinfectant after each use to reduce odour and pathogen spread
  • Designate a specific disposal location — bags of waste should be stored in sealed containers and disposed of away from your shelter location when safely possible
  • Wash hands with any available water and soap or alcohol after each use

Handwashing and hygiene: Even minimal handwashing (soap and very small amounts of water) reduces disease transmission dramatically. Maintain hand hygiene especially before food handling and after waste contact. Alcohol-based hand sanitiser is a valuable addition to supplies.

Waste management in extended shelter:

  • Maintain strict separation between clean (food, water, first aid) areas and sanitation areas
  • Dispose of food waste in sealed containers to prevent pest attraction
  • Manage used dressings and medical waste carefully to prevent cross-infection

Battery Power Management

Power management in extended shelter determines how long you can maintain lighting, communications, and medical equipment.

Priority power allocation:

  1. Medical devices (oxygen concentrators, continuous monitoring equipment) — highest priority
  2. Communications (radio receiver, phone charging) — critical for situational awareness
  3. Lighting — LED lights are vastly more power-efficient than incandescent
  4. Other uses (cooking, heating) — only with surplus

Battery and power stock planning:

  • Stock ample AA and AAA alkaline batteries for radios and flashlights
  • Maintain at least one fully charged power bank per phone user, plus means to recharge it
  • Solar charging panels (even small ones) can recharge power banks during daylight hours when safely positioned
  • Limit generator use to essential charging only during high-risk periods (see Light Discipline article)

Communications

Maintaining situational awareness during shelter requires functioning communications.

  • Battery/crank AM/FM/shortwave radio: The most important communications device in extended shelter — independent of cell networks, internet, and power infrastructure; can receive government emergency broadcasts and BBC World Service
  • Mobile phone: Battery-powered; keep on airplane mode when not actively in use to extend battery life; use only for critical calls and messaging
  • Satellite communicator: If available (Garmin inReach, SPOT) — can send messages and receive check-ins when cellular networks are down
  • Pre-agree with family members, your employer, and contacts on a check-in schedule so that missed check-ins trigger an appropriate response

Managing Children During Extended Shelter

Children in prolonged shelter face a compounded challenge: they do not understand why they cannot go outside, they have less capacity to self-regulate fear and boredom, and their physical needs — for movement, stimulation, and play — conflict with the demands of security.

Practical management:

  • Maintain as normal a routine as possible within the shelter: regular mealtimes, sleep schedules, and activity periods
  • Provide age-appropriate explanation of the situation — children cope better with honest, age-appropriate information than with confused silence
  • Physical activity within the shelter: stretching, movement games, tasks that use energy
  • Books, drawing materials, board games, puzzles — analogue activities independent of power
  • Give children age-appropriate responsibilities: filling containers, maintaining a daily log, managing small tasks. Responsibility reduces helplessness
  • Watch for signs of psychological deterioration (severe regression, persistent nightmares, complete withdrawal, aggressive outbursts) and provide calm reassurance and extra attention
