Conduct a low profile search of the exterior grounds and public areas of the building. Conduct a comprehensive search having all staff search their work area, in addition to the grounds and public areas so the entire building is covered. Search with partial evacuation. Evacuate after searching or 5. Evacuating immediately is an alternative that on face value appears to be the preferred approach, however, under certain circumstances evacuating personnel may increase rather than decrease the risk of injury.
Bombs are three times more likely to be planted outside buildings than inside.
A bomber wishing to cause personal injuries could place a bomb in the shrubbery near an exit. Public areas inside the school are the second most frequent place devices are located. Any evacuation that requires students and staff to move through public areas such as halls, public restrooms, lobbies, parking lots, playgrounds, might increase the risk of injury during any detonation. As a result many administrators are identifying staff willing to help investigate when these calls occur. School personnel are perhaps in the best position to scan the building for suspicious objects because they know when something is out of place.
