Recovery Phase 4
Recovery Phase 4 : The period following the response when immediate threat to human life has passed and general evacuation has ceased. This phase includes- (1) Recovery: Recovery decontamination refers to the actions taken to restore an affected area to its pre-emergency condition. Thus, it refers to the process of reducing exposure rates and concentrations in the environment to acceptable levels for unconditional occupancy or use after the emergency phase of an accident or incident. Recovery differs from reentry in that recovery encompasses the efforts and resources needed to return the affected area to its pre-accident condition. Recovery includes both short- and long-term activities. Short-term recovery returns vital systems to minimum operating standards, seeks to restore critical services to the community, and provides for the basic needs of the public. Long-term recovery focuses on restoring the community to its normal, or improved state of affairs and on returning life to normal or improved levels. The recovery period is also an opportune time to institute mitigation measures, particularly those related to the recent emergency. (2) Reentry: Reentry deals with persons entering an affected (i.e., contaminated or potentially contaminated) area following a release. The terms controlled reentry, restricted reentry, occupational reentry, and emergency reentry refer to the temporary, short-term readmission of persons (primarily emergency workers) into a restricted zone for the purpose of performing specific tasks (such as monitoring teams). The terms uncontrolled reentry, unrestricted reentry, and general reentry are used in the context of uncontrolled, permanent re-access referring to those provisions leading up to unlimited public access, reoccupation, or use of previously restricted zones after the hazards have been reduced to acceptable levels or have been declared "clean." (3) Restoration: Removal and decontamination of all NBC agents, removal of any rubble, and emergency repair of structures and facilities. The culmination of these activities is reestablishment of major utilities and services and the return of social and economic activities to near-normal levels. The terms recovery and restoration have been used in combination to refer to the entire group of activities undertaken to prepare a previously contaminated and restricted area for unlimited reoccupation and/or use by the public
