A High Condition is declared when there is a high risk of terrorist attacks. In addition to the measures taken in the previous threat conditions, federal departments and agencies will consider the following protective measures:
Coordinate necessary security efforts with federal, state, and local law enforcement agencies, National Guard or other security and armed forces;
Take additional precautions at public events, possibly considering alternative venues or even cancellation;
Prepare to execute contingency procedures, such as moving to an alternate site or dispersing the workforce; and
Restrict access to a threatened facility to essential personnel only.
