A disaster plan is essential for ensuring the safety and well-being of individuals and communities during emergency situations. The inclusion of a backup plan for supplies is crucial because access to fundamental resources can be severely impacted during a disaster.

Therefore, focusing on power and water when developing a disaster plan addresses two critical aspects of survival in emergency situations.
