People might wonder where to store emergency supplies. Well, it could be in a closet or a room, but make sure this place is accessible during an emergency.
For instance, if the power went out, why should a person have to stumble all the way to the basement to get their supplies? So in cases where it might be dark, keep lighting supplies on every level.
But in the case of an emergency where a person will have to stay somewhere to be safe, the basement is best. Make sure to have a room that people can sit in in the case of a tornado or hurricane.
If a person lives in a trailer, then the person should consider building a cellar. These are very important in times of tornado. If the land is owned by a trailer park, then ask the landlord for permission to build one. If they refuse, try to get the law involved.
