Cette barrière est conservée pendant les opérations de déclassement, jusqu'à ce que, devenant sans utilité et elle-même décontaminée, elle puisse être mise hors service ou démantelée à son tour; enfin la troisième barrière est constituée par le bâtiment maintenu en dépression par la ventilation. 2, record 2, French, - d%C3%A9chet%20de%20d%C3%A9classement
