The Fire Department is familiar with the location and nature of the B-829 Facility as well as <br /> access roads in the area. <br /> I-4.4.1 Release Response for Hazardous Materials and Waste <br /> Due to the robust construction of the B-829 Facility, it is not likely that an emergency involving <br /> the release of hazardous waste would occur. In the event of a major disaster(fire,earthquake, <br /> etc.)that disturbs the integrity of the cap or the drainage system, appropriate maintenance and <br /> repairs will be performed as soon as possible. <br /> This Contingency Plan will be implemented if a fire, explosion,extreme weather or earthquake <br /> compromises the integrity of the cap that releases hazardous waste or hazardous waste <br /> constituents which could threaten human health or the environment. <br /> The detection of hazardous waste constituents in groundwater samples obtained from the B-829 <br /> well network at concentrations exceeding Statistical Levels is not considered a release to the <br /> environment. This Contingency Plan is not implemented for groundwater monitoring program <br /> detections. <br /> I4.4.2 Fire or Explosion <br /> If a fire or explosion occurs,personnel are instructed to do the following: <br /> • Evacuate the area or proceed to a designated safe area and radio the Emergency Dispatcher <br /> the following information: <br /> — Name. <br /> — Location of the incident. <br /> Nature of the incident. <br /> • Any additional information that might affect the response personnel (for example,severity of <br /> the fire or materials at risk in the immediate area). <br /> • Remain on the radio, if safe to do so, to verify the information given to the Emergency <br /> Dispatcher and receive instructions. <br /> • Notify their supervisor. <br /> • Isolate the emergency area. <br /> • Give emergency aid to the injured,if safe to do so. <br /> I-4.4.3 Earthquake <br /> During a significant earthquake, employees follow the Self-help Plan safety and evacuation <br /> guidelines. After the shaking stops, and if safe to do so,Facility employees: <br /> • Radio the Emergency Dispatcher to report emergencies and to request emergency assistance <br /> if necessary. <br /> LLNL Site 300 Contingency Plan 1-4-6 January 2019 <br /> Appendix 14,Building 829 <br />
