LLNL Emergency Management Plan (EPlan) Rev 27 January 2022 70 5 EMERGENCY CATEGORIZATION AND CLASSIFICATION This section provides an overview of the process used for categorization and classification of Operational Emergencies. Specific actions and criteria for categorization and classification of Operational Emergencies are described in PPD procedures. In accordance with DOE requirements, an Operational Emergency is defined as a major unplanned or abnormal incident or condition that involves or affects DOE facilities and activities by causing or having the potential to cause serious health and safety or environmental impacts and requires additional resources to supplement the planned initial response. Operational Emergencies are characterized by: • A requirement for resources from outside the immediate/affected area or local event scene to supplement the planned initial response, and • A requirement for time-urgent notifications to initiate response and/or protective actions activities at locations beyond the event scene. Most events at LLNL that involve an emergency response (fire, medical, HazMat, etc.) are not Operational Emergencies. The event severity/complexity and the expected or required response determine if an Operational Emergency declaration is warranted. As required by DOE Order 151.1D, LLNL under its Emergency Management Hazardous Materials Program must have provisions to classify incidents involving the actual or potential airborne release of (or loss of control over) hazardous materials from an onsite facility/activity as an Alert, Site Area Emergency, or General Emergency based on health effects parameters measured or estimated at 30 meters, 100 meters, and the site boundary, respectively, and compared with the appropriate Protective Action Criterion. 5.1 Definitions 5.1.1 Operational Emergency Categories LLNL must declare an Operational Emergency when an incident occurs that represent a significant degradation in the level of safety resulting in potential health and safety hazards to workers or the public. Operational Emergencies must be categorized as promptly as possible. Types of Operational Emergencies: • Health and Safety (including hazardous materials) • Environment • Safeguards and Security • Offsite LLNL Transportation Activities • Hazardous Biological Agent or Toxins • Other emergency conditions at the discretion of the EMDO or LEDO/ED (e.g., offsite emergency affecting LLNL)
