7.1 Release Response for Hazardous Materials and Waste <br /> 7.1.1 Fire Department Response <br /> Releases from Level 1,2 or 3 incidents must be stabilized by the Fire Department,which has <br /> established event scenarios and consequences(Run Cards)that are used for responding to <br /> hazardous material emergencies. These response guidelines describe possible scenarios,time to <br /> consequence,evacuation protection zones,and recommended actions among other information. <br /> In the event of a Level 1, 2 or 3 incident at a Site 300 Facility, Facility personnel can provide <br /> technical expertise for the material(s) involved in the incident, support for hazardous material <br /> release cleanup, and resolution of explosive waste incidents. <br /> 7.1.2 Container-failure Response <br /> If a container being used to manage hazardous waste or material releases its contents to the <br /> environment, and if there is no immediate threat to personnel safety, Facility personnel cease <br /> waste handling operations and take immediate action to contain the release using the procedure <br /> described in Section 8. <br /> Containers of explosives that exhibit evidence of leaking or fuming are regarded as extremely <br /> hazardous.The ES&H Team is notified immediately. <br /> 7.2 Releases to the Atmosphere <br /> If an accidental release to the environment occurs,release response is implemented. If the Fire <br /> Department declares the incident a general emergency,the LLNL Atmospheric Release Advisory <br /> Capability(ARRC) System is utilized.The LLNL ARAC System is also activated for an air <br /> release greater than the Reportable Quantity established in the Comprehensive Environmental <br /> Response, Compensation, and Liability Act(CERCLA),or if an LLNL Industrial Hygienist <br /> determines that a release on site has an effect off site. <br /> — ARAC is a system designed to estimate the effects and atmospheric dispersion of <br /> hazardous and toxic waste releases within the immediate area surrounding a release <br /> or within northern California.The ARAC Central Facility is equipped to perform <br /> detailed atmospheric-dispersion calculations, allowing an accurate tracing of <br /> hazardous-and toxic-waste dispersion. This system allows the various response <br /> teams to have immediate information on hazardous-and toxic-waste concentrations <br /> resulting from an accidental release. <br /> 7.3 Fire or Explosion <br /> If a fire or explosion occurs,personnel: <br /> • Evacuate the area or proceed to a designated safe area and dial 911 or(925)447-6880 <br /> from an on-site phone or use a radio to give the Emergency Dispatcher the following <br /> information: <br /> — Name. <br /> — Location of the incident(building,room, area)or any other information that might <br /> help the emergency response personnel quickly locate the scene. <br /> -- Nature of the incident(fire, electrical, chemical, etc.). <br /> LLNL Site 300 Contingency Plan 21 January 2019 <br />
