You can probably think of many more. Plan your kit well. Make it your own and tailor it to your needs. The temptation may be to buy a ready-made emergency preparedness kit, and some of these have some very useful items, but they are more expensive and can be quite dangerous. You will think you are prepared, but then if it comes to using it, you may not know what to do with each items.
Most items are easy to find in a drugstore or in a camping and backpacking store.
A good deal of the items can be found around your home. A Knife- sturdy 2 bladed. A Boy Scout or Swiss Army variety is best because it is multi-use. Several large leaf bags for instant body shelter from the sun or cold weather. Retail stores do sell convenient solar blankets that will provide the same protection.
