How to use these tools

Start with the readiness test to see where you stand, print the power outage checklist and keep it with your flashlights, and fill in the family emergency plan together. When the lights do go out, open the food safety calculator on your phone before you throw anything away. For the background behind every number, see our free preparedness guides.
