Along with water, food, and shelter, sanitation is one of the most critical things to consider in an emergency situation. There are two aspects of sanitation as far as e-prep is concerned.
First is the literal disposal of sewage and waste. We have touched on this subject briefly and you may wish to check out this post on Emergency Sanitation Kits. This post also has a free handout on making your own sanitation kit.
The second component of sanitation involves practicing good hygiene for cleanliness and health reasons. Without taking sanitary measures, diseases such as diarrhea and cholera may occur.
