Protect cold food

Ready.gov says a refrigerator keeps food cold for about four hours if kept closed, while a full freezer can hold a safe temperature for about 48 hours. Use a thermometer when possible.

Store practical food

Favor shelf-stable foods your household already eats, with manual-opening and preparation methods that do not depend on grid power.

Treat water as a system

Store drinking water, know local advisories, and plan for people, pets and sanitation—not just a few bottles.

Safety: Fuel-burning camp stoves, grills and generators belong outdoors, away from windows, doors and garages. Never use an oven or gas stovetop to heat the home.

What to do next

Turn this topic into one or two concrete household actions. Preparedness works better as a maintained system than as a one-time shopping list.
