72-Hour Survival Kit: The Mini, Grab-and-Go, and Full Versions
Most people picture one bag when they hear "72-hour survival kit," but Alberta's own emergency preparedness guidance actually recommends three different kits, each built for a different situation. This guide covers the three-tier system, what a full kit needs, what ready-made kits usually miss, and how to actually maintain it.
What Goes in a 72-Hour Survival Kit, According to Official Guidance
Before getting into the three-tier system, it helps to know the baseline every kit is built from, since the three tiers are really just this same list, split by how much warning time you have.
Per Alberta's emergency preparedness program, a 72-hour survival kit is a container of essential supplies meant to sustain a household for a minimum of 72 hours, reflecting that household's specific needs. The core categories are consistent with the national 72-hour standard used across provinces: water, non-perishable food, first aid, a flashlight, a radio, and any medications.
A few of these deserve more than a passing mention. Water needs work out to roughly 2 litres per person per day for drinking, cooking, and basic hygiene, so a household of four should plan for close to 24 litres to cover the full 72 hours. Food should genuinely require no cooking or refrigeration, since you can't assume either will be available. A battery or hand-crank radio matters more than it sounds like it should: if cell towers go down during a major storm, a radio is often the only way to receive official updates, since it runs on radio waves rather than cellular infrastructure. Our guide to preparing for power outages during weather warnings goes deeper into keeping communication devices charged and a family contact plan in place before a warning is even issued.
One detail that's easy to overlook: a kit only helps if it's stored somewhere every household member knows and can reach quickly, not buried in a basement behind seasonal decorations.
That's the full kit. Official guidance actually breaks preparedness into three distinct kit types, not just one.
The Three-Tier Kit System: Mini Kit, Grab-and-Go, and Full Kit
Each tier is built for a different amount of warning time, from zero notice to a planned departure, and understanding which situation each one covers makes the whole system click.
Tier | Built For | What Goes In It |
Mini kit | Everyday carry | Small cash, hand sanitizer, wipes, backup medication, spare glasses or contacts, paper and pen, important phone numbers |
Grab-and-go list | Fast evacuation | Portable charger and cords, cash, water and snacks, a change of clothes, laptop, external hard drive, irreplaceable items (photos, heirlooms), keys |
Full 72-hour kit | Home base | The complete supply list, sized to sustain the household in place or support a longer evacuation |
The mini kit is meant to live in a bag you already carry daily, small enough that you barely notice it's there. It's not meant to sustain you through a disaster; it's meant to bridge you to somewhere safer or to your fuller kits.
The grab-and-go list is a different exercise entirely. It's built for leaving in minutes, not packing methodically, so everything on it should already be gathered in one place before you ever need it, not scattered across the house waiting to be remembered under pressure. This is also the tier where a lot of Canada's own emergency guidance overlaps: Emergency Preparedness Week runs every May specifically to get households thinking through exactly this scenario before wildfire or storm season makes it urgent.
Those three tiers cover planning. A lot of people skip the DIY process and just buy a kit instead, which comes with its own blind spot.
What Most Ready-Made Survival Kits Miss
Commercially available 72-hour kits are a fast starting point, and they cover the basics, food, water, first aid, reliably enough that buying one isn't a bad decision on its own.
The common gap is power. Most pre-made kits include a flashlight and maybe a couple of spare batteries, but nothing that can actually keep a phone, medical device, or radio running for the full 72 hours. That gap matters most exactly when it's hardest to ignore: if cell towers are down, a phone burns through battery fast just searching for signal, and a medical device like a CPAP machine or a home oxygen concentrator simply stops working once its own battery runs out.
Regional risk also plays into how big this gap actually is in practice. A household in Atlantic Canada dealing with a multi-day outage after a post-tropical storm has very different needs than one in British Columbia bracing for wildfire smoke and evacuation orders, or one on the Prairies riding out an ice storm. Our breakdown of power outages across Canada, east versus central versus west covers how those regional patterns should actually shape what you pack, beyond the generic national checklist.
Whether store-bought or self-assembled, a few extras are easy to forget until you actually need them.
Documents and Extras Worth Adding
Supplies keep you fed and connected. Documents are what get a household back on its feet once the immediate emergency has passed, and they're the category people remember only after they've already needed them once.
As per Alberta's checklist, that means: ID, passports, birth and marriage certificates, insurance policies, wills and powers of attorney, health care numbers, recent photos of family members, and pet registration and vet information. If your household includes kids, pack a comfort item and a printed list of allergies or medications for anyone who might need to be looked after by someone other than you. If you have pets, their vaccination records and a photo can matter more than you'd expect if you're separated during an evacuation.
One practical habit worth building in: keep both a hard copy, in a fireproof or waterproof container, and a digital backup, on a USB drive or in secure cloud storage. Either format alone has a failure point, a house fire destroys the hard copy, a dead phone locks you out of the digital one, so having both covers the gap.
Once the kit is built, the real risk is letting it sit untouched for years.
Where to Store and How to Maintain Your Kit
A kit is only as good as its worst-maintained item, so storage and upkeep matter as much as what's actually in it, and this is the step most households skip entirely once the initial kit is packed.
Store all three tiers somewhere accessible and known to every household member: the mini kit in a daily bag, the grab-and-go list ready near the door, the full kit in an easy-to-carry container like a backpack, duffel, or rolling bag. For maintenance, check expiry dates on food, water, and medications roughly every six months, and recharge any power equipment on the same cycle so it isn't sitting dead in the closet the one time you actually need it.
If your household deals with wildfire or heat risk specifically, EcoFlow CA's guide to a 72-hour emergency kit for summer disasters is a useful season-specific companion to this general checklist, since it covers the same three-part structure with wildfire-specific adjustments layered on top.
Conclusion
A real 72-hour survival kit isn't one bag. It's a mini kit for daily carry, a grab-and-go list for fast evacuation, and a full kit for sustained self-sufficiency. Most ready-made kits only really cover the third tier, and even then, without real power backup.
Build or buy the base kit, then add the power gap yourself rather than assuming a store-bought kit already covers it. The DELTA 3 Max Plus and DELTA 3 Ultra Plus pages linked above cover the grab-and-go and full-kit tiers respectively.
FAQs
What's the difference between a mini kit, a grab-and-go kit, and a full survival kit?
A mini kit is small enough for daily carry and bridges you to safety. A grab-and-go kit is built for leaving in minutes during a fast evacuation. A full kit is the complete 72-hour supply list for sheltering in place or a longer evacuation.v
What do most store-bought 72-hour kits leave out?
Power. Most include a flashlight and spare batteries at best, with nothing that can keep a phone, medical device, or radio running for the full 72 hours, which matters most in exactly the situations where cell service is already unreliable.
How much water and food do I actually need for 72 hours?
Plan on roughly 2 litres of water per person per day, close to 24 litres for a family of four across 72 hours, plus enough non-perishable food that needs no cooking or refrigeration to cover the same window
What documents should I keep in my emergency kit?
ID, passports, birth and marriage certificates, insurance policies, wills and powers of attorney, health care numbers, recent family photos, and pet registration and vet information, kept as both a hard copy and a digital backup.
How often should I check or refresh my survival kit?
Roughly every six months. Check expiry dates on food, water, and medications, and recharge any power equipment on the same schedule so it's ready when you actually need it.
Do I need a separate kit for each family member?
The mini kit and grab-and-go list are personal enough that each family member benefits from their own version, while the full 72-hour kit is typically built and stored at the household level.
