A complete emergency go bag holds supplies for at least 3 days of evacuation, centered on water, food, light, first aid, and key documents.
For the full breakdown, see our best Emergency Go Bag guide.
When an evacuation order hits, you get minutes to grab what matters. The difference between chaos and a smooth exit comes down to one thing: a go bag packed and waiting by the door. The U.S. government’s ready.gov guidance lays out exactly what belongs inside, and the list is shorter and more practical than most expect—one bag, one grab, three days of independence.
What Belongs In An Emergency Go Bag
Ready.gov breaks the core kit into clear categories: water, food, light, communication, first aid, sanitation, tools, and personal items. Each solves a problem you will face within 72 hours of an evacuation.
- Water and food: One gallon of water per person per day for at least three days, plus a 3-day supply of non-perishable, easy-to-prepare food and a manual can opener.
- Light and power: Flashlight, extra batteries, a battery-powered or hand-crank radio (a NOAA Weather Radio with tone alert is ideal), and a cell phone with chargers and a backup battery.
- First aid and health: A full first aid kit, a 7-day to 1-month supply of medications, dust masks, and soap or hand sanitizer.
- Sanitation: Moist towelettes, garbage bags, and plastic ties for personal waste.
- Tools and safety: Whistle to signal for help, wrench or pliers to shut off utilities, duct tape, plastic sheeting, and scissors.
- Documents and cash: Paper copies of IDs, insurance policies, and contact information, plus extra cash and local maps. Phones die; paper does not.
- Comfort and clothing: A change of clothes, sturdy shoes, a blanket or sleeping bag, and weather-appropriate gear.
That list covers a single adult. If your household includes kids, a baby, an older relative, or pets, add their supplies to the same bag or a labeled second one.
Water And Food: How Much Is Actually Enough
The official water rule is one gallon per person per day for at least three days, split between drinking and basic sanitation. Many households keep a separate, larger water supply for home sheltering while the go bag carries the first day’s worth plus a way to filter or purify more.
Food follows the same logic. Pack a minimum of three days of non-perishable items needing no cooking or just hot water. Canned goods, protein bars, dried fruit, and shelf-stable nut butters beat anything requiring a stove. Check expiration dates twice a year and rotate what you eat out of the kit.
Build The Kit Right: Steps That Matter
Assembling a go bag is a one-hour project if you follow the official sequence from ready.gov: gather the supplies, pack them into a single durable bag, and store it in a known, accessible spot near an exit. Keep a written medication list and copies of key documents inside a sealed plastic bag so they survive weather and rough handling. Update digital photos of your family every six months so current images exist for identification or reunification.
Once packed, resist borrowing from it. A flashlight that lives in the go bag but gets used for a weekend camping trip is one that is not there when the alarm sounds. Treat the bag as a sealed system, and restock anything you remove within the same day.
Where The Checklist Goes Wrong
The most common failure is packing for home sheltering instead of evacuation. A kit that assumes you can stay put and use your kitchen is useless when you must walk away. The second failure is skipping paper backups. If your phone dies and you have no printed contacts or documents, you lose your ability to reach anyone or prove who you are. The third is forgetting specifics: a manual can opener for canned food, extra batteries for the radio, and the daily medication a family member takes.
Most households also miss the distinction between a general kit and a car kit. Cold-weather and vehicle guidance adds an ice scraper, snow shovel, jumper cables, and warm clothes. If you live anywhere with real winters, keep a separate bag in the trunk rather than making one kit do both jobs.
FAQs
How Often Should I Update My Go Bag?
Check the bag twice a year, ideally when you change the clocks. Rotate expired food and water, confirm medication refills are current, update photocopied documents, and swap in season-appropriate clothing. This twice-a-year rhythm keeps the kit ready without demanding constant attention.
Can I Use A Regular Backpack For A Go Bag?
A sturdy, dedicated backpack works well, provided it is comfortable to carry under weight and reserved exclusively for emergency use. A bag borrowed for daily errands will be missing critical items when needed. If you use a standard pack, keep it clearly labeled and off-limits.
What Is The Best Way To Store Water In A Go Bag?
Use sealed, durable water bottles or pouches designed for long-term storage, and replace them on your twice-a-year schedule. Avoid reusing milk jugs or thin bottles that crack under pressure. For evacuation, commercially sealed water packs are lighter and easier to distribute than large jugs.
