Bomb Threat Stand-Off Distances
Graphic of evacuation distances
1 Preferred area (beyond this line) for evacuation of people in buildings and mandatory for people outdoors.
2 All personnel in this area should seek shelter immediately inside a building away from windows and exterior walls. Avoid having anyone outside—including those evacuating—in this area.4
3 All personnel must evacuate (both inside of buildings and out).

1Based on maximum volume or weight of explosive (TNT equivalent) that could reasonably fit in a suitcase or vehicle.

2Governed by the ability of typical US commercial construction to resist severe damage or collapse following a blast. Performances can vary significantly, however, and buildings should be analyzed by qualified parties when possible.

3Governed by the greater of fragment throw distance or glass breakage/falling glass hazard distance. Note that pipe and briefcase bombs assume cased charges that throw fragments farther than vehicle bombs.

 4A known terrorist tactic is to attract bystanders to windows, doorways, and the outside with gunfire, small bombs, or other methods and then detonate a larger, more destructive device, significantly increasing human casualties.

This table is for general emergency planning only. A given building's vulnerability to explosions depends on its construction and composition. The data in these tables may not accurately reflect these variables. Some risk will remain for any persons closer than the Outdoor Evacuation Distance.
