Note: The Hebrew acronym is given at the beginning of the first four definitions:
HADAB – Security Room: A reinforced room inside the residence built with a concrete shell (8”/20cm. thick) and having a door and a window capable of withstanding shock waves. (Security rooms are built only close to potential areas of conflict.)
- MAMAD – Secure Residential Space: A room constructed of concrete inside the residence, and having a door and window constructed of two parts: the external one is of steel and is capable of withstanding shock waves, and the internal one is single-winged, on an axis, and sealed against gases. (These have been constructed in new residences since 1992.)
- MAMAK – Story-wide Secure Space: A concrete-constructed space located in a common area of the story, and intended for use by the residents of a number of apartments. It has a door capable of withstanding shock waves, an emergency rescue opening in the ceiling, and two air hoses in the floor. (These have been constructed in new apartment buildings since 1992.)
- MAMAM – Institutional Secure Space: This is identical to the story-wide secure space, and is located in institutional buildings.
- Secure Room: A room located as far as possible from the direction of the imminent threat of rocket fire. It is best if the room has a minimum of external walls, windows and openings.
Private Shelter (not requiring one to move from one structure to another): This is constructed with a concrete shell, and is located on the ground floor or in the basement. It has an anti-shock wave steel door, and a steel emergency exit measuring 60x80 cm. (24”x32”), both with rubber sealing strips. It is best to follow the recommendations publicized in the media and choose the secure space based on specific directions for given locations in the country.
Public Shelter: Similar to the private shelter, but located outside the residence.
Secure Space: This is a general term including the HADAB, the MAMAD, the MAMAK and the MAMAM.
