Preparing for an emergency comes down to four things: supplies to sustain your household for at least 72 hours, a communication plan so your family can reconnect if separated, copies of critical documents you’d need to rebuild your life, and enough familiarity with your plan that you can act on it under stress. Most of this takes a single afternoon to set up and a few minutes twice a year to maintain.
Water and Food: The Non-Negotiables
Water is the first priority. The CDC recommends storing at least 1 gallon per person per day for a minimum of three days. That covers both drinking and basic hygiene. A family of four needs 12 gallons just for the baseline, and you should store more if anyone is pregnant, sick, or if you live somewhere hot. Pets need water too, roughly a quarter to a half gallon per day depending on size.
Store commercially bottled water when possible, since it has the longest shelf life. If you fill containers from your tap, use food-grade plastic and replace the water every six months. For food, stock at least a three-day supply of items that don’t need refrigeration or cooking: canned goods, peanut butter, granola bars, dried fruit, crackers. Include a manual can opener. If anyone in your household has dietary restrictions or food allergies, plan around those now rather than discovering the gap during an actual emergency.
Building Your Supply Kit
Beyond food and water, a solid emergency kit includes:
- Light and communication: Flashlight, extra batteries, a battery-powered or hand-crank radio (ideally a NOAA Weather Radio with tone alerts), and a cell phone charger with a backup battery pack
- First aid kit: Bandages in assorted sizes, sterile gauze pads, adhesive tape, antibiotic ointment, antiseptic wipes, tweezers, an instant cold compress, nonlatex gloves, and a thermometer. The Red Cross recommends stocking enough for a family of four, which means at least 25 adhesive bandages, two compress dressings, and an emergency blanket.
- Safety tools: A whistle for signaling help, dust masks for filtering contaminated air, plastic sheeting with duct tape and scissors for sealing a room if you need to shelter in place, and a wrench or pliers for shutting off gas or water lines
- Sanitation: Moist towelettes, garbage bags, and plastic ties
- Navigation: Local maps, since your phone’s GPS may not work if cell networks go down
Keep everything in a single grab-and-go container, like a large waterproof bin or a duffel bag stored near your door. If you have a car, consider keeping a smaller duplicate kit in the trunk.
Your Family Communication Plan
Cell networks get overwhelmed during emergencies. When thousands of people try to call at once, congestion can make local calls impossible. That’s why the FCC recommends designating an out-of-area contact as your family’s central point of communication. If a disaster separates you, every family member calls or texts the same person in another state rather than trying to reach each other directly. Long-distance calls often get through when local ones don’t.
Write this contact’s name and number on a card that each family member carries. Don’t rely on your phone’s contact list alone, since a dead or damaged phone takes all those numbers with it. Pick a local meeting spot (a neighbor’s house, a nearby park) and a secondary location farther away in case you can’t return to your neighborhood. Text messages use less bandwidth than voice calls, so texting is more likely to go through when networks are strained.
Protecting Your Critical Documents
If your home is destroyed, the documents inside it are gone too. FEMA publishes an Emergency Financial First Aid Kit checklist that covers everything you’d need to prove your identity, file insurance claims, and access your money. The key categories:
- Identification: Copies of driver’s licenses, birth certificates, Social Security cards, passports, marriage or divorce records
- Financial accounts: Bank and credit card account numbers, retirement and investment account information, vehicle registration and titles
- Insurance policies: Homeowners or renters insurance, auto, life, flood, and any riders. Include photos of your property and valuables.
- Housing: Copies of your lease, mortgage documents, or property deeds
- Estate planning: Wills, trusts, and powers of attorney
- Income records: Recent pay stubs, government benefit information, tax returns
Store physical copies in a waterproof, fireproof portable container. Back up digital copies to a secure cloud service or an encrypted USB drive you keep in a separate location. This is the single most overlooked piece of emergency prep, and it’s the one people regret skipping most after a disaster. Replacing a birth certificate or proving home ownership from scratch can take weeks or months.
Preparing for Pets
Many emergency shelters don’t accept animals, so your plan needs to account for where your pets will go. Build a separate pet kit that includes a collar with a current ID tag, a leash or carrier, and enough food and water for at least three days. Keep copies of vaccination records and rabies certificates, since boarding facilities and emergency shelters that do accept pets will require proof of vaccinations before entry.
Store your pet’s microchip number and registration information with your kit. One often-recommended item: a photo of you and your pet together, which helps prove ownership if you’re separated and need to reclaim them later. If your pet takes medication, keep a supply in the kit along with dosage instructions.
Shelter in Place vs. Evacuate
The right response depends entirely on the type of emergency. The general principle: you shelter in place when the risk of moving is greater than the risk of staying, and you evacuate when a direct threat is approaching or already at your location.
Shelter in place during chemical spills, hazardous air events, or situations where going outside increases your exposure. This means sealing yourself in an interior room, closing all windows and vents, and using plastic sheeting and duct tape to block gaps around doors and windows. Evacuate immediately for fires, flooding, or any event where staying means the danger reaches you. If local authorities issue an evacuation order, follow it. People consistently underestimate how quickly conditions can deteriorate.
Know your evacuation routes in advance. Identify at least two ways out of your neighborhood, since your primary route could be blocked. Keep your car’s gas tank at least half full as a habit, not just when a storm is forecast.
The Mental Side of Preparedness
Having supplies matters less if you freeze when it counts. Research from Harvard’s FXB Center for Health and Human Rights found that self-efficacy, the feeling that you can actually handle difficulties, is one of the strongest predictors of whether someone takes effective action during a disaster. People who reported higher self-efficacy were less likely to perceive barriers to evacuation, even when facing the same objective conditions as those who didn’t evacuate.
The practical takeaway: familiarity builds confidence. Walk through your plan with your household at least once. Make sure everyone knows where the kit is, who the out-of-area contact is, and what the meeting points are. Schools that run disaster drills have found that children often become the most effective communicators of preparedness strategies within their families. If your kids participate in school drills, ask them what they practiced and reinforce it at home.
Maintaining Your Kit Over Time
A kit you packed three years ago and never touched is a kit full of expired food, dead batteries, and stale water. Set a twice-a-year reminder, many people tie it to daylight saving time changes, to rotate your supplies. Replace stored water every six months. Check expiration dates on food, medications, and batteries. Update documents if you’ve moved, changed insurance, or had a change in family size. Swap out clothes in your kit if children have outgrown them.
This maintenance pass takes 15 to 20 minutes and is the difference between a kit that works and one that gives you a false sense of security.
