SHELTER SUPPLIES
Not every item on this chart is vital to life. (The most essential ones are outlined in color.) But even though you might be able to leave your shelter briefly after a day or two, you should prepare to be completely self-sustaining for at least two weeks.
The one essential is water; most people can live no more than four days without it. The minimum for a shelter is one quart of fluid per person per day; if space is available near the shelter, a gallon of water per day per person would provide for your comfort, including washing.
Some items, such as tools, should be kept handy but need not be inside the shelter itself.
