Quick answer
An emergency kit is a ready-packed set of supplies that keeps your household going for several days without help. Start with water (1 gallon per person per day), food, a radio, a flashlight, a first aid kit and spare batteries. Then add medicine, documents and cash.
After a storm, earthquake or long power outage, stores close and help can take days. A kit means you don’t have to go looking for basics when it is least safe.
Ready.gov recommends supplies for at least several days. The Red Cross suggests 3 days in a bag you can carry and 2 weeks at home. Start small and build up.
