LLNL Emergency Plan Rev-23 October 2017 80 8 PROTECTIVE ACTIONS The Laboratory has procedural actions for protection of onsite personnel and recommendations to offsite agencies in the event of an Operational Emergency. As required by DOE Order 151.1D, LLNL must provide immediate notification to affected onsite employee of the need to take protective actions. While this process may involve sending the notification via building public address or other site systems, it cannot take longer than 10 minutes after the need for protective actions has been identified by the IC or EMDO. There are three basic protective actions that may be implemented to limit injury and death of the LLNL population caused by a n emergency condition. These are: • Evacuation • Shelter-In-Place (for an airborne hazardous material release) • Lockdown (for an active onsite security threat) This section of the Emergency Plan addresses the first two protective actions that are associated with the airborne release hazardous materials. Protective Action Criteria are levels of hazardous material that, if observed or predicted, indicate action is needed to prevent or limit exposure to the hazard. These actions are noted on the EALs and Protective Action Sheets that have been developed for each EPHA facility at LLNL. The ACFD IC will direct initial protective measures based on the initial size-up, information provided to him/her, and applicable Protective Action Sheets. The EMDO will then verify that the initial protective measures are consistent with the protective actions contained in the applicable EAL. If the EAL indicates that a hazardous material plume may extend beyond the site boundary or that Protective Action Criteria may be exceeded offsite, the EMDO will make protective action recommendations to the ACFD IC and to offsite agencies through Emergency Programs Organization plans/procedures for emergency notifications. Protective actions for the offsite public may be ordered only by public officials or their designees (e.g., ACFD, LPD); the EMDO/ED will make recommendations only. 8.1 Protective Action Criteria 8.1.1 Protective Action Guides (Radiological) The Protective Action Criteria for radiological materials are contained in the EPA’s Manual of Protective Action Guides and Protective Actions for Nuclear Incidents, EPA 400-R-92-001 (May 1992). The PAG is the value that is used to classify Operational Emergencies and to initiate appropriate protective actions.
