Start With a Home Emergency Kit Checklist

Building home emergency kits starts with one honest question: if the power went out tonight and stayed out for three days, what would your household actually need from its home emergency kits? The answer is smaller and cheaper than most people expect, and it fits in a single storage bin.

At North American Tactical Supply, we sell survival gear for a living, so here is our blunt take: most families do not need a bunker. They need a plan, a checklist, and a bin they can grab without thinking. A home emergency kit is a stored set of supplies that keeps your household fed, hydrated, lit, and reachable for at least 72 hours without outside help. That is the baseline the Ready.gov emergency kit guidance recommends, and it is where every household should start.

Below, we break down exactly what to buy, how much of it, and how to keep it usable instead of letting it rot in a closet.

The Core Supplies Every Kit Needs

The core of any kit breaks into five buckets. Keep them in one place, ideally in a sealed bin near your main exit.

• Water: stored drinking water plus a way to treat more
• Food: non-perishable, no-cook options and a manual can opener
• First aid: a stocked kit, your medications, and a reference guide
• Light and power: flashlights, batteries, a portable charger
• Documents and cash: copies of IDs, insurance, and a small amount of cash

Everything else is a layer on top. Do not overthink the first pass.

Quantities by Household Size

Quantities scale with people, not with square footage. Use this table as your shopping reference:

Add one extra gallon per pet per day for drinking and cleanup.

Water: One Gallon Per Person Per Day

Water is the supply people underestimate most. The standard rule is one gallon per person per day, and that covers drinking, basic cooking, and light hygiene. For a three-day kit, that means three gallons per person. For a two-week shelter-in-place supply, it means 14 gallons per person.

Storing that much water takes space, so most households split the job:

• Bottled water for drinking, rotated every few months
• Water pouches for grab-and-go bags, since they pack flat and store well
• A treatment method for refilling from a questionable source

For treatment, our water purification tablet strips cost $0.99 and treat 10 liters, one tablet per liter with a 30-minute wait. A personal water purification straw at $14.99 lets you drink directly from a stream or tap you would not otherwise trust. For compact storage, our six-pack of water pouches runs $2.50 and slips into any bag.

Food and First Aid for a 72-Hour Emergency Kit

A 72-hour emergency kit needs food you can eat cold and first aid you can use one-handed in the dark. That is the whole design brief.

Non-Perishable Food That Stores Well

Stock food that needs no cooking, no refrigeration, and no cleanup. Good choices:

• Canned beans, tuna, and fruit with a manual can opener
• Peanut butter, crackers, and granola bars
• Instant oatmeal and shelf-stable milk
• Dried fruit and nuts
• Electrolyte packets

Rotate food every six to twelve months by eating what you store and restocking. Label each item with the date you bought it.

Medications and Medical Supplies

Prescription medication is the item most kits miss. Keep a three-day supply of any daily medication in your kit, rotated with your regular refills. Add:

• A stocked first-aid kit with bandages, gauze, and antiseptic
• A seven-day pill organizer
• Spare glasses or contacts
• A printed list of medications and allergies

A pocket reference helps when stress hits. Our 52-page first aid guide with CPR and AED instructions costs $1.99 and meets current OSHA and ANSI first aid guidelines. It is the cheapest insurance in the bin.

Building an Emergency Kit for an Apartment

An emergency kit for an apartment looks different from a house kit. Space is tighter, exits are shared, and evacuation may mean stairs. Keep the kit in one rolling bin or a heavy-duty backpack near your door.

Apartment-specific additions:

• Sturdy shoes and a flashlight by the bed, since stairwells go dark
• A go-bag you can carry down several flights without stopping
• Copies of your lease and renter's insurance in a waterproof sleeve
• A battery-powered radio for building-wide alerts
• A small fire extinguisher rated for kitchen and electrical fires

If you have mobility needs, pack gear you can use without setup. A purification straw beats a pump filter when hands are shaky.

Lighting, Power, and Communication Backup

Light and communication fail together in most outages. Plan for both.

• Flashlights: one per person plus one for common areas, with spare batteries
• Headlamps: hands-free light for repairs and first aid
• Portable charger: a charged power bank for phones
• Battery or hand-crank radio: for official updates when cell service drops
• Emergency contacts: written on paper, not just saved in your phone

Charge power banks monthly and test flashlights quarterly. A dead flashlight you find in an emergency is worse than no flashlight, because you planned around it.

Your Emergency Kit Maintenance Checklist

An emergency kit maintenance checklist is what separates a real kit from a pile of expired cans. Storage conditions matter as much as the checklist itself: heat, light, and moisture shorten the life of food, water, batteries, and medications, so keep the bin in a cool, dry interior closet rather than a garage, attic, or basement that floods.

Where to store it:

• A sealed plastic bin with a latching lid in a climate-controlled closet near your main exit
• A smaller grab-and-go bag near the door for evacuation
• A second small stash in the car if you commute

Rotation and expiration management:

• Water: commercially bottled water typically carries a printed date; rotate every six to twelve months. Water pouches often have a five-year shelf life, so check the printed date and rotate on that schedule. Store tap water in food-grade containers and replace every six months.
• Food: rotate every six to twelve months by eating what you store and restocking. Label each item with the purchase date. Canned goods generally hold quality for two to five years, but rotate on the shorter end so you are not relying on a decade-old can.
• Batteries: test flashlights quarterly and replace alkaline batteries every one to two years even if they still work. Remove batteries from devices you do not use often to prevent corrosion.
• Medications: keep a three-day supply rotated with your regular refills. Check expiration dates twice a year and replace anything expiring within six months.
• Power banks: charge monthly. Lithium-ion cells lose capacity if left fully drained.

Twice-yearly checklist (set two calendar reminders):

• Check water dates and replace expired bottles or pouches
• Rotate food by eating and restocking older items
• Test flashlights and swap any weak batteries
• Charge power banks and test the radio
• Check medication expiration dates
• Confirm documents and cash are current
• Restock first-aid supplies used during the year
• Update the kit for household changes (new baby, new pet, new medical need)
• Verify the bin is still dry and the lid seals

Budgeting and Lower-Cost Alternatives

You can build a solid starter kit without spending much. Buy in this order:

1. Water and a treatment method first. Cheapest and most critical.
2. Food you already eat. Buy extra of what is on your shelf.
3. Light and power. Flashlights and one power bank.
4. First aid and your medications. Non-negotiable.
5. Documents and cash. Costs almost nothing.

Lower-cost moves that work:

• Store tap water in food-grade containers instead of buying bottled
• Use a purification straw or tablets instead of a full filter system
• Build the kit over several grocery trips instead of one purchase
• Skip gear you will not use; a $40 gadget you never open is wasted money

Conclusion

The hard part of preparedness is not buying gear. It is starting, and then keeping the kit current as your household changes. Most families put it off for years, then wish they had started sooner.
