Building a Simple Home Emergency Kit

Most emergencies at home are unglamorous. The power goes out for eighteen hours, a storm makes the roads impassable for two days, or the water supply is interrupted while a main is repaired. Nobody needs a bunker. People need drinking water, a light that works, a way to hear what is happening, their daily medication, and enough food that they are not driving to a shop in dangerous conditions.

The other reliable truth is that kits decay. Batteries corrode, tinned food passes its date, the torch was borrowed for a camping trip. So this guide gives quantities you can count, and treats the maintenance schedule as part of the kit rather than an optional extra.

Two kits, not one

The two situations pull in opposite directions, which is why one combined box does neither job well. Sheltering at home means weight does not matter and the target is several days of normal living without utilities. Leaving quickly means everything fits in a bag one person can carry, grabbable in under a minute.

Build the stay-at-home store first, since it covers the most likely scenarios and can live under a bed. Then build a smaller go-bag duplicating the essentials in miniature, kept near the door you would leave by. A go-bag assembled from the main store during an emergency is not a go-bag.

Water: the one number to get right

The widely published emergency-preparedness guidance is about one gallon of water per person per day, roughly four litres, for at least three days, with two weeks recommended at home where space allows. That figure is not just drinking; it covers basic hygiene and food preparation too.

For a household of three, three days is nine gallons, about thirty-four litres, or roughly two dozen large bottles, which fits in the bottom of a wardrobe more easily than people expect. Two weeks is around forty-two gallons, which means a stackable container or two alongside.

Commercially bottled sealed water is simplest and carries a date to check. If you fill your own, use food-grade containers, never ones that held milk or juice, since residual sugars support bacterial growth. Add more than the baseline if anyone is pregnant, unwell or on medication that increases fluid needs, if you live somewhere hot, or if you have pets. Purification tablets or a small filter belong in the go-bag as a backup, not a substitute.

Food you will actually eat

Three days of shelf-stable food per person for the go-bag, two weeks at home if space allows. The criterion that matters is no cooking, no refrigeration and minimal water, because the scenarios that empty your fridge are the ones that take out your hob.

• Tinned protein such as fish or beans, plus a manual can opener, the most commonly forgotten item in any kit

• Peanut butter or a similar high-calorie spread, and crackers or another long-life carbohydrate

• Dried fruit, nuts and cereal bars, which give calories per gram and need no preparation

• Long-life milk, and instant coffee or tea if that matters to household morale, which it does more than people admit

• Ready-to-eat tinned soups and fruit, ideally in ring-pull tins, and comfort food, especially if children are involved

Store food your household eats normally, which is what makes rotation happen naturally rather than as a chore. A camping stove with spare fuel is a worthwhile addition, but only if you can use it outdoors or in a genuinely ventilated space. Burning fuel indoors is a carbon monoxide risk, and it kills people in exactly these circumstances.

Light, power and information

A torch per person, and a head torch beats a hand torch for anyone who needs both hands. Store spare batteries outside the devices, because batteries left in a torch for three years leak and destroy the contacts. Candles are a poor primary light source, particularly with children or pets around.

For information, keep a battery or hand-crank radio. When the mobile network is down and the power is out, broadcast radio is often the only thing still telling you what is happening. Where a public weather or alert broadcast exists, choose a radio that receives it, and enable emergency alerts on your phone.

A charged power bank, ideally two, covers phones for a couple of days. Keep the right cables with them and top them up at every kit check, since they self-discharge over months. A whistle carries much further than a voice and weighs nothing.

First aid, medicine and sanitation

A basic first aid kit with plasters, sterile dressings, tape, antiseptic wipes, tweezers, scissors, gloves, a foil blanket and pain relief covers almost everything that happens at home. Buy a prepared kit, add to it, and check it, since the contents get raided for everyday cuts and never replaced.

Prescription medication is the part people most often get wrong. Aim for at least a seven-day supply of anything taken daily, with a written list of names, doses and prescribing details. Prescriptions are dispensed on a schedule, so ask your pharmacy about building a small buffer legitimately rather than skipping doses. Anything needing refrigeration, such as insulin, needs its own plan, because a cool bag is not a fridge. Include spare glasses and hearing aid batteries.

Sanitation is the category people skip and then regret within a day of a water outage. Heavy-duty bin bags, wet wipes, hand sanitiser, toilet paper, soap and, if you can, a bucket with a well-fitting lid, plus menstrual products and nappies as appropriate. These are the cheapest items on this list and among the most missed.

Documents, cash and the practical extras

Copies of identity documents, insurance policies, tenancy or mortgage paperwork and medical information in a waterproof folder, plus the same set stored digitally. Add a written list of important phone numbers, because nobody memorises numbers and a dead phone takes the contact list with it.

Keep some cash in small denominations. Card terminals and cash machines depend on power and networks, and small notes matter because change may not be available. A spare set of house and car keys belongs here too.

A few practical extras: pliers and an adjustable spanner, so you can turn off the water stopcock or gas if instructed; work gloves; a dust mask; sturdy shoes near the bed, since broken glass is a common injury after storms; and warm layers plus a blanket each. Know where your stopcock, fuse board and gas shut-off are, and make sure someone else does too.

Rotation: put two dates in the calendar

This is the difference between a kit and a box of expired items. Two checks a year, six months apart, tied to something memorable such as the clock change. Each takes about twenty minutes.

1. Check every date: bottled water, tinned and packet food, medication, first aid supplies and hand sanitiser. Move anything close to its date into the kitchen to be used, and replace it.

2. Test the torches and radio, and inspect batteries for corrosion or swelling. Replace any you are unsure about.

3. Recharge power banks to full and confirm the cables still fit your current phones, which change more often than kits do.

4. Reassess quantities against who lives here now: new baby, new pet, someone moved out, someone on new medication.

5. Check children's clothing and shoe sizes, since a bag stocked eighteen months ago may contain nothing that fits.

6. Test the smoke and carbon monoxide alarms on the same schedule.

Store it all in a labelled container somewhere cool, dry and reachable without a ladder, and tell everyone in the household where it is. A kit only one person can find is half a kit.

What goes wrong, and who needs more than the standard list

The classic failure is the one-off assembly with no maintenance. A kit built enthusiastically in one afternoon and never opened again is, four years later, a box of expired painkillers, leaking batteries and food nobody would eat.

The second failure is cannibalisation. The torch goes camping, the plasters treat a graze, the power bank goes in a suitcase, and the batteries end up in a remote control. The fix is a rule that things return the same day, plus a separate, deliberately cheap spares drawer for everyday use.

The third is buying a sealed pre-made kit and never opening it. No manufacturer knows your medications, your family's sizes or your local risks, so you meet its contents for the first time in the dark.

The fourth is preparing for the wrong event. Flood-prone areas need documents stored high and a plan for moving upstairs; wildfire areas need a go-bag ready and a low tolerance for delay; winter storm areas need heat and layers above all. Check what your local emergency service advises rather than copying a generic list, this one included.

Children and babies

Formula, bottles and a way to sterilise them, nappies and wipes in current sizes, and familiar food. Add comfort items and something to do, because boredom during a two-day power cut is a genuine morale problem. Teach older children where the kit is and how the torch and radio work.

Pets

Three days minimum of food and water for each animal, calculated separately from the human total, plus bowls, a lead or carrier, litter and any medication. Keep vaccination records and a recent photo of the animal with you in it, which matters if you are separated, and check in advance which local shelters accept animals, because many do not.

Limited mobility, chronic illness or sensory impairment

Store the kit where you can reach it without steps or lifting, split across two or three smaller containers rather than one heavy box. Keep spare batteries or a manual backup for any powered equipment, and if you rely on mains-powered medical devices, contact your electricity supplier, since many maintain a priority services register for exactly this. Write your specific needs on a card in the kit, and agree in advance with a neighbour who will check on you.

Small flats and renters

Storage is the real constraint, and the answer is distribution rather than reduction. Water fits under a bed, food joins the kitchen store on a designated shelf, and the go-bag hangs in the hall cupboard. Renters should confirm with the landlord or managing agent where the stopcock and consumer unit are, since in flats these are sometimes in a communal area you have never seen, and should read any building-wide emergency procedure before needing it.

Build the water and the light first, add the rest over a few weeks, and set the two calendar reminders on the day you finish. That last step is what keeps the whole thing alive.

If a nudge helps you do the twice-yearly check, TaskTreasury runs focused sessions on real-life tasks and pays Treasury Credits for finishing them.
