One of the Most Difficult Emergency Decisions to Be Made

One of the most difficult emergency decisions to be made involves the evacuation of a building because of a bomb threat, especially because statistics show that over 95 percent of such threats are hoaxes. Suppose your firm's switchboard operator receives such a threat, wherein the caller identifies himself as a member of a recognized terrorist group and gives the location of the bomb as to floor as well as the time of detonation. Which of the following actions should receive priority as to evacuation?

A) Promptly consider evacuation.
B) Call the FBI to have a subversive check made on the terrorist group.
C) Secure advice from the FBI as to evacuation.
D) Conduct a detailed search of the area involved and make a decision relative to evacuation after the search is completed.
E) Do not evacuate, as odds are 95 percent in your favor that it is a hoax.
