How this item fits a household plan
Use official kit guidance first. Ready.gov still starts with water, food, light, a radio, and a first-aid kit. A long-outage plan then adds water treatment, battery carbon monoxide alarms, sanitation, and a way to stay informed if home Wi-Fi is dead. This catalog is a companion to the book, not a requirement to buy 50 things this month.
