Do some research to make sure you are not wasting your time on implausible risks. How likely is it that you would have to face this particular danger, and how much damage can it conceivably cause? For example, do you live in a 100-year flood zone? In the path of tropical storms? In a high-crime neighborhood? Be sure to search around and study publicly available resources; reaching out to local emergency response organizations can be a good plan, too. Try to focus on reputable sources; the science in doomsday movies and on conspiracy websites seldom checks out.
