A household shelter (HS) is designed and constructed for the protection of people against weapon effects during a National Emergency. It should not be used for protection during other emergency situations such as a fire in a building. For quick access, HS is located inside the individual house or flat.

HS shall be incorporated as part of the house or flat. This can be achieved by efficient space planning as well as optimal integration of the HS location with other spaces in a house or flat.
