A disaster supplies kit is simply a collection of basic items your household may need in the event of an emergency. Make sure you and your family have enough emergency food and water to see you through at least 72 hours. Depending on the severity and location of the catastrophe, it may take time for help to arrive and for shelters and food to become available.
As a general rule, you should store three days' worth of supplies. If room and resources allow, store more.
Replace emergency food and water supplies every six months unless otherwise noted on the packaging
Make sure your kit is easily accessible. When a disaster hits, you don't want to dig in the back of the attic for your supplies.
Keep smaller versions of your disaster kit in your family vehicles and at work.
Prioritize. Don't get overwhelmed by the need to get everything on the list. Focus on the essentials (water, food, and medications) and build from there. Some people find it helpful to have a disaster calendar and add one or two items to their kit every time they go to the grocery/hardware/discount store.
