Included are unforeseen events having adverse impact on operations or presenting a dangerous environment, including, but not limited to, power failures involving Government agencies as a whole, acts of terrorism, civil disobedience, riots, fire, transportation strikes, etc. The foregoing types of situations may vary in their intensity and the area affected.  The Co-Chairs of the Emergency Preparedness and Advisory Committee should be notified by an appropriate official of any agency when, in that official’s judgment, a situation involves Government agencies as a whole and is of sufficient magnitude to jeopardize the health and safety of Federal employees. Either the early dismissal plan or the off-hours notification plan described in Section II will be invoked, as appropriate.
