LLNL Emergency Plan <br />Rev-22 <br />January 2017 <br /> <br /> 69 <br />Operational <br />Emergency <br />Category <br />Indicators <br />Security  Actual unplanned detonation of an explosive device or a credible threatened <br />detonation. <br /> An actual terrorist attack or sabotage event involving a site/facility or operation. <br /> Kidnapping or the taking of hostage(s) involving a site/facility or operation. <br /> Damage or destruction of a site or facility by natural or malevolent means <br />sufficient to expose classified information to unauthorized disclosure. <br />Hazardous <br />Biological <br />Agents/Toxins <br /> Any actual or potential release of a hazardous biological agent or toxin outside <br />of the secondary barriers of the biocontainment area. <br />Offsite <br />Transportation <br />Activities <br /> The radiation dose from any release of radioactive material or the concentration <br />in air from any release of other hazardous material is expected to require <br />establishment of an initial protective action zone. <br /> Failures in safety systems threaten the integrity of a nuclear weapon, <br />component, or test device. <br /> A transportation accident that results in damage to a nuclear explosive, nuclear <br />explosive-like assembly, or Category I/II quantity of special nuclear material. <br />5.3 Emergency Action Levels/Protective Action Sheets <br />5.3.1 Emergency Action Levels Description <br />Emergency Action Levels (EALs) are specific, pre-determined, observable criteria used by the <br />EMDO to recognize and identify that the incident is an Operational Emergency. Once this <br />discovery is made, EALs are used by the EMDO to help determine appropriate protective actions <br />for onsite personnel and protective action recommendations for offsite populations. For each <br />facility for which an Alert, Site Area Emergency or General Emergency is defined, the EALs <br />describe on-scene indicators, list the distance to the nearest site boundary, and describe the <br />conditions and indicators upon which the classification is based, including the maximum <br />distances at which the PAG or AEGL60-2 values would be observed. EALs are developed for <br />potential Operational Emergencies, including radiological and non-radiological releases, <br />terrorism and sabotage (malevolent acts), fires, explosions and natural phenomena. <br />EALs are developed from scenario input data and results provided in facility-specific EPHAs. <br />Trigger points for hazardous material EALs are specific initiating conditions/indicators, such as <br />alarms and/or direct observations of spills or fires that are based on the potential to release <br />accident-specific source terms analyzed in EPHAs. The EPHAs also provide a quantitative <br />estimate of the consequences of each EAL at specific receptor locations, such as the facility <br />boundary, site boundary, and the maximum distance at which the PAG or AEGL60-2 is exceeded. <br />This last estimate allows determination of the emergency classification associated with the <br />release.
