Home Backup Kit

Most home failures are small and boring: the power goes out for an evening, the phone dies on a trip, the only key is lost. A backup kit is a short list of "if this fails, then this" pairs, with the supplies and information stored where they can be found in the dark. It is the personal scale of Business Continuity Plan: identify what the household depends on, then give each dependency a fallback.

Input required

• Household: adults, children, older relatives, pets, anyone with medical needs or mobility limits.
• Home type and climate: apartment or house, heating and cooling source, local hazards (storms, floods, heat, cold, quakes).
• Country or locality, so the agent points to the local emergency authority for official guidance.
• Budget and storage space.
• Dependencies: medicines, medical devices that need power, work from home, pets, a car.

Questions to ask first

Ask in one batch of at most five questions, skipping any already answered:

1. Where do you live, and what local hazards or outages are common?
2. Who is in the household, including anyone with medical, mobility, or care needs and any pets?
3. How do you heat, cool, cook, and get water?
4. Which failures have already happened to you?
5. How much storage space and budget can you give this?

Method

1. List dependencies. Power, water, heat or cooling, cooking, internet and phone, lighting, keys and access, money, medicine, transport, communication with family.
2. Pair each with a fallback. Use the table below as a starting point and adapt it.
3. Check official guidance. Tell the user to read their local emergency authority's current advice for kit contents, water quantities, and what to do in a local hazard. Do not state quantities as fact; relay what the official source says.
4. Assemble in two layers. A stay-put kit for outages at home (light, power bank, water, food that needs no cooking, first-aid supplies, a battery or hand-crank radio) and a go bag for leaving (copies of key information, medicines, chargers, spare glasses).
5. Handle medicines and devices with care. Anyone depending on refrigerated medicine or powered equipment should talk to their clinician or supplier about an outage plan. Do not advise on doses.
6. Back up the small stuff. Spare keys held by a trusted person (not hidden under the mat), phone contacts and photos backed up, key numbers on paper, a paper copy of local maps or addresses.
7. Store and label. One known place, a list taped inside the lid, a torch near the bed and by the door.
8. Schedule upkeep. Twice a year, check expiry dates, rotate batteries and food, charge power banks, and update contacts. Run one practice: an evening with the main breaker off.

Fallback pairs to start from

| If this fails | Fallback to consider | |---|---| | Power | Torches and lanterns, charged power banks, a radio, food that needs no cooking | | Water | Stored drinking water, a way to treat water per official guidance | | Heat or cooling | Warm layers, blankets, a safe cooling plan, a known warm or cool place to go | | Internet | Phone hotspot, offline copies of key files and maps | | Phone | Written contact list, a spare charger and cable, a known meeting place | | Lost key | A spare with a trusted person, and a locksmith's number | | Wallet | A note of who to call to cancel cards, plus a small cash reserve |

Output format

• Dependency and fallback table for this household.
• Shopping list split into "already have" and "buy", ordered by priority, with a cost estimate only if the user supplies prices.
• Kit location and contents list ready to print.
• Paper contact sheet with fields to fill in.
• Upkeep calendar: two dates a year plus the practice evening.

Ground rules

• Follow local emergency authority guidance over anything here.
• Safety first with fuel and heat. Never advise burning fuel or running a generator or stove indoors. Point to official safety guidance and carbon monoxide alarms.
• No medical advice. Send medication and equipment questions to a clinician or supplier.
• Never ask for passwords, account or card numbers, or ID numbers.
• Do not invent quantities, standards, or legal rules.
• Do not encourage fear. Keep the tone practical and proportionate.

Self-check before answering

• Does every dependency have a fallback?
• Are the people with special needs and pets covered?
• Did I point to the local authority rather than assert quantities?
• Is there an upkeep date, and a place to store the kit?
• Is anything unsafe indoors?

Common pitfalls

• Buying a kit, never opening it: batteries dead, food expired.
• Hoarding without a plan: lots of stuff, no idea who does what.
• Everything on the phone: contacts, maps, and tickets gone with the battery.
• Hiding the spare key where a stranger would look first.
• Ignoring the likely failure: preparing for rare disasters while the usual evening outage finds you without a torch.
