Preparing an Emergency Survival Kit
Loading expected effects…
What it is
Assembling a ready-to-use 72-hour household emergency kit containing water (one gallon per person per day for three days), non-perishable food, a first aid kit, a battery-powered or hand-crank radio, a torch with spare batteries, copies of critical documents, cash, medications, and basic sanitation supplies. The kit is stored in an accessible location, checked every six months to replace expired consumables, and kept current with household changes (new medications, new household members). The one-time assembly cost is typically $50–150 depending on household size and starting inventory. The kit addresses the most probable emergency scenarios – short-term natural disasters, power outages, and local disruptions – where households must be self-sufficient for 72 hours before relief services become available.
Sources and key statistics
- A 72-hour emergency kit is the standard preparedness baseline recommended by FEMA, the Red Cross, and equivalent agencies globally; it targets the period between disaster onset and when organised relief services become operational
- Core components: three days of water (one gallon per person per day), three days of non-perishable food, first aid kit, battery-powered or hand-crank radio, torch, spare batteries, whistle, dust mask, plastic sheeting and duct tape, moist towelettes, bin bags, wrench or pliers, manual can opener, local maps, mobile phone chargers, and cash in small denominations
- FEMA’s 2023 National Household Survey found that only 48% of US adults had assembled or updated disaster supplies in the prior year, and SafeHome.org research (2025) found just 5% of homes have a fully stocked kit – indicating most adopters of this intervention are moving from a near-zero baseline
- A 2016 systematic review in AJPH found no RCT evidence directly linking kit possession to improved survival or self-sufficiency outcomes; the mechanism is plausible and universally recommended but empirically unverified, making this a low-evidence intervention despite strong face validity
- A 2024 systematic review and meta-analysis of household preparedness interventions found no statistically significant effect on preparedness supplies outcomes and only a small positive effect on preparedness behaviours, with very low certainty of evidence

How to do it
- Start with the FEMA/Ready.gov checklist as a baseline: one gallon of water per person per day for three days, three days of non-perishable food, a basic first aid kit, a battery-powered radio, a torch with batteries, a multi-tool or basic toolkit, dust masks, and sanitation supplies; add household-specific items (prescription medications, infant supplies, pet food) before purchasing anything
- Store the kit in a single, clearly labelled, portable container (a waterproof tote or dedicated backpack) in a location all household members know – near an exit is conventional; avoid attics or locations that may become inaccessible
- Photograph or scan critical documents (passports, insurance policies, prescriptions, bank account information) and store copies both in the physical kit and encrypted cloud storage
- Set a recurring six-month calendar reminder to rotate perishable items (water, food, batteries, medications) before expiry – tying this to daylight-saving time changes is a common mnemonic
What success looks like
- Every household member can locate the kit and knows what it contains, without prompting, within two minutes
- No item in the kit has expired, and the kit has been reviewed within the last six months
- The household can sustain basic water, food, light, and communication needs for 72 hours without any external assistance or supply run
Common pitfalls
- Assembling the kit once and never revisiting it – water degrades in non-food-grade containers, food expires, and batteries discharge in storage, rendering the kit unreliable precisely when it is needed
- Over-engineering the first version: spending weeks planning the perfect kit rather than assembling a functional 80% version this week; a partial kit is substantially better than no kit
- Storing the kit in an inaccessible location (locked garage, high shelf, car boot) that may not be reachable during the emergency scenario the kit is designed for
Prerequisites
- Sufficient household storage space for a medium-sized tote or backpack in an accessible location
- Basic literacy to follow a preparedness checklist and read expiry dates on consumables
- Access to a retail or online supplier for basic emergency supplies (widely available in most countries)
