Active Threat Emergency Procedure

An active threat situation has become a serious and possible threat to any environment.  An active threat is any incident that creates an immediate threat or presents an imminent danger to the Jefferson Lab community.  No one knows how any individual will respond during an active threat emergency; however, those who have been given guidance are more likely to remain calm and react appropriately.

The procedure outlined in this appendix applies when any of the following active threat criteria is confirmed:


·         Sighting of a firearm

·         Discharge of a firearm

·         Person(s) injured by gunshot

·         Property damaged by gunshot


This appendix is written in coordination with ES&H Manual Chapter 3510 Emergency Response Activities.  All relevant content within the chapter applies to the procedure outlined in this appendix.
