The 14-Day Emergency Kit: A Practical Household Planning Guide
Quick Start: Top 5 Essentials
- Water: 1 gallon per person per day — the single most critical item in any emergency kit.
- Potassium Iodide (KI) Tablets: Protects the thyroid from radioactive iodine. Use only when directed by official authorities.
- Battery-powered or hand-crank radio: A resilient way to receive official information if power or mobile networks are disrupted.
- Dust masks and hygiene supplies: A mask may help reduce inhalation of dust, but it does not shield the body from penetrating radiation.
- First-aid supplies and prescribed medicines: Include items appropriate to your household while following medical advice.
Building a household emergency kit is not about fear — it is about taking a practical, responsible step that gives your family a measurable advantage in any disruption, from a week-long power outage to a more serious regional emergency. The 2026 FEMA Ready.gov emergency supply guidelines and the CDC's emergency preparedness recommendations both converge on the same core principle: a prepared household places far less strain on emergency services and is significantly more likely to emerge from a crisis without serious harm. This guide translates those official guidelines into an actionable checklist, with clearly labeled planning assumptions rather than universal or medically individualized quantities.
Official Guidance: "Assemble a kit of emergency supplies. Have enough supplies for at least several days to two weeks." — FEMA Ready.gov, Nuclear Explosion Preparedness (2026)
The Absolute Essentials: Water and Nutrition
Water is the most critical and most commonly underestimated item in any emergency kit. Water is essential, and in a grid-down or contamination scenario, tap water cannot be assumed safe. Ready.gov lists 1 gallon of water per person per day for several days, for drinking and sanitation. A 14-day household plan would therefore use 56 gallons for four people as a planning estimate, not as a universal FEMA minimum. Household needs can be higher because of heat, illness, physical exertion, or individual needs; plan with those factors in mind.

Water Storage: Practical Guidelines
- Use commercially sealed bottled water (the simplest option) or food-grade water storage containers rated for long-term use (look for BPA-free, HDPE plastic).
- Store containers away from direct sunlight and away from chemical products — water can absorb vapors through thin plastic over time.
- If using tap water to fill containers, the CDC recommends adding 8 drops of unscented liquid chlorine bleach (6% concentration) per gallon, then sealing and storing for up to 6 months.
- Include water purification tablets (iodine or chlorine dioxide) as a backup for water of uncertain quality.
- A gravity-fed water filter (such as a Berkey or Sawyer) adds a second layer of protection, though note that standard filters do not remove dissolved radioactive ions like cesium-137 — sealed commercial water remains the gold standard for radiological scenarios.
Food: 14-Day Non-Perishable Supply
FEMA recommends foods that require no refrigeration, minimal preparation, and no additional water. Aim for approximately 2,000 calories per adult per day. Prioritize variety to maintain morale during extended shelter-in-place periods.
- Canned goods: vegetables, fruits, beans, tuna, chicken, and soups (include a manual can opener — this is frequently forgotten)
- Protein bars, energy bars, and meal-replacement bars (compact, calorie-dense, long shelf life)
- Peanut butter, almond butter, and nut mixes (high calorie density, no refrigeration needed)
- Dried fruit, trail mix, and granola
- Crackers, rice cakes, and shelf-stable bread
- Instant oatmeal, dried pasta, and instant rice (if water supply allows cooking)
- Infant formula and baby food if applicable — store at least a 30-day supply
- Special dietary foods for household members with medical conditions (diabetic-friendly, gluten-free, etc.)
Source: FEMA Ready.gov — Food and Water in an Emergency: "Store at least a three-day supply of non-perishable food. Consider a two-week supply for home."
Health, Hygiene, and Specialized Gear
Medical infrastructure is among the first systems to become overwhelmed in a major emergency. Hospitals fill quickly, pharmacies close, and supply chains for medications break down within days. Building a robust medical and hygiene component into your emergency kit is not optional — it is the difference between managing a minor injury at home and facing a life-threatening situation without resources.
- Comprehensive first-aid kit: Bandages (multiple sizes), sterile gauze pads, adhesive tape, antiseptic wipes, antibiotic ointment, burn cream, elastic bandage (ACE wrap), thermometer, scissors, tweezers, and disposable gloves. The American Red Cross publishes a detailed first aid kit checklist that serves as a reliable baseline.
- 30-day supply of all prescription medications for every household member. Talk to your physician about obtaining an emergency supply — many insurers and state programs allow early refills for emergency preparedness purposes.
- Hand-crank NOAA Weather Radio (with AM/FM): The National Oceanic and Atmospheric Administration's Weather Radio All Hazards network broadcasts continuous emergency alerts on dedicated frequencies. A hand-crank model works without batteries or grid power — this is your primary information source when all other networks fail.
- N95 respirator masks (one per person, minimum 5 per person): NIOSH-approved N95 masks filter 95% of airborne particles, including fine dust and radioactive fallout particulates. Standard surgical masks do not provide adequate filtration for particulate hazards. Store in sealed plastic bags to maintain integrity.
- Potassium Iodide (KI) tablets: KI protects the thyroid gland from absorbing radioactive iodine (I-131) released in nuclear events. Critical note: KI should only be taken when directed by official public health authorities — it provides no protection against other forms of radiation and can cause harm if taken unnecessarily, particularly in people with thyroid conditions or iodine sensitivity. The FDA-approved dosing for adults 18–40 is 130 mg; for children 3–18 years, 65 mg; for infants, 16–32 mg. See the FDA's official KI guidance for complete dosing tables.
- Plastic sheeting (4–6 mil thickness) and duct tape: Used to seal windows, doors, and ventilation openings to create a temporary shelter-in-place barrier against airborne contaminants. FEMA recommends pre-cutting sheets to fit each room's openings before an emergency, so they can be deployed in minutes. Store with scissors.
- Hand sanitizer (70%+ alcohol), soap, and personal hygiene supplies: Sanitation prevents secondary infections that become serious when medical care is unavailable. Include toilet paper, feminine hygiene products, and waste disposal bags.
- Extra eyeglasses or contact lens supplies if applicable — a frequently overlooked item that can become critical over a 14-day period.
Tools and Communication
Power outages are the most common consequence of any major emergency, and they can last days to weeks. Your kit should allow your household to function safely without grid power.
- Flashlights (LED): At least two per household, with extra batteries stored separately. LED flashlights provide far longer battery life than incandescent models. Avoid candles — they are a fire hazard in enclosed shelter-in-place environments.
- Extra batteries: Store in a waterproof container, separate from devices to prevent corrosion. Include AA, AAA, and any other sizes used by your devices.
- Portable power bank (pre-charged): Allows charging of mobile phones for as long as cellular networks remain operational.
- Whistle: A simple, battery-free signaling device. Three short blasts is the universal distress signal.
- Multi-tool or Swiss Army knife: Covers a wide range of practical needs in a compact form.
- Written family emergency plan: Document your shelter location, family meeting points if separated, and the phone number of an out-of-state contact who can serve as a communication hub. Practice this plan with all household members before any emergency occurs.
- Copies of important documents in a waterproof container: government-issued IDs, passports, insurance policies, bank account information, and medical records. Digital copies on a USB drive are a useful supplement but not a replacement.
- Cash in small bills: ATMs and card readers will not function during a power outage. Keep enough cash to cover several days of basic needs.
What NOT to Buy: Save Your Money
The emergency preparedness market is filled with expensive products marketed to civilians that provide little practical benefit over well-chosen basics. The most common example is military-grade hazmat suits and full-face gas masks. These items are designed for trained professionals operating in known chemical or biological environments — they require specific training to don and doff correctly, and an improperly fitted gas mask provides less protection than a properly worn N95 respirator. For civilian shelter-in-place scenarios, the combination of a sealed interior room, N95 masks, and plastic sheeting provides the protection FEMA actually recommends.
Claims that general-purpose "survival" filters remove all radioactive contamination are not reliable. Filter performance depends on the radionuclides and the product's verified design. A practical baseline is to store commercially sealed water and follow official local guidance. A filter's performance depends on the radionuclides and the product's verified design, so do not assume a general-purpose filter removes radioactive contamination. Focus the budget on water storage, food, a battery-powered or hand-crank radio, and first-aid supplies. These items address the actual risks in the actual scenarios you are most likely to face.

Frequently Asked Questions
Why do experts recommend 14 days of supplies instead of 3 days?
Ready.gov recommends keeping food, water, and other supplies for several days. A 14-day plan is an optional extended household-preparedness scenario, not a universal FEMA requirement. Fallout levels vary by event, weather, terrain, and location; the 7/10 rule is a simplified decay model and does not authorize evacuation or outdoor activity. Follow official instructions for sheltering and movement.
Does a standard weather emergency kit work for other disasters?
Yes. The core foundation — water, non-perishable food, and a hand-crank radio — applies to virtually all emergency scenarios: severe storms, prolonged power outages, earthquakes, and radiological events alike. The primary difference between a general emergency kit and a nuclear-specific kit is the addition of scenario-specific items: KI tablets, N95 masks, and plastic sheeting for sealing. If you already have a solid general emergency kit, upgrading it to cover radiological scenarios requires relatively modest additional investment.
How often should I check my emergency supplies?
Every 6 months is the standard recommendation. A practical approach is to tie your review to the twice-yearly daylight saving time changes — the same reminder used for smoke detector battery checks. At each review: rotate food and water (consume items approaching their expiration date and replace them), check medication expiration dates, test battery-powered devices, and verify that all household members still know the family emergency plan. A kit that has not been reviewed in two years may have expired medications, depleted batteries, and outdated contact information — none of which you want to discover during an actual emergency.
