What to Buy for a 72-Hour Emergency Preparedness Kit for a Family of Four

A 72-hour emergency preparedness kit is designed to sustain your family for three days in the event of a natural disaster, power outage, or other crisis where you may need to shelter in place or evacuate quickly. For a family of four, this means carefully calculating supplies like water, food, and medications to ensure everyone, including children and pets, has what they need to stay safe and comfortable. FEMA and the American Red Cross both recommend that every household maintain a kit like this, and building one from scratch is more straightforward than most people expect.

The core categories to focus on are water, food, first aid, light and communication, and important documents. Water is the most critical element, you'll need at least one gallon per person per day, meaning a minimum of 12 gallons for a family of four over 72 hours. Non-perishable foods should require little to no cooking, and you should account for any dietary restrictions or allergies within your household. A hand-crank or battery-powered radio, flashlights with extra batteries, and a fully stocked first aid kit round out the essentials.

Beyond the basics, a well-built kit also includes copies of vital documents like birth certificates, insurance policies, and medical records stored in a waterproof container. Comfort items, cash in small bills, a manual can opener, and sanitation supplies like wet wipes and hand sanitizer can make a significant difference during a stressful situation. Building your kit incrementally over a few weeks can help spread out the cost, and storing it in a designated, easily accessible location, such as a large backpack or rolling bin, ensures your family can grab it and go at a moment's notice.
