You may not have room to put everything you might need into the portable first aid kit you squeeze into your 72 hour kit. You should have a separate household first aid kit, both for disaster preparedness and for household emergencies; it may be found useful for camping trips as well. There are a number of items that may be stored in this kit, but what is in your kit depends on your situation. The contents may differ, depending on the age(s) and activities of all family members. And, as with many preparedness kits, its contents may grow as your family grows, and its contents may increase as you see additional hazards loom.
Here are some useful resources to consider when building your first aid kit:

Make a First Aid Kit: First aid kits come in many shapes and sizes. You may purchase them from a variety of vendors, or you may plan and build your own. Whether you buy a first aid kit or put one together, make sure it has all of the items you need in an emergency.

First Aid Kits: Stock supplies that can save lives. A well-stocked first-aid kit can help you respond effectively to common injuries and emergencies.
