Based on the situation, it may be determined that the best way to keep people safe is to evacuate them from the building. Evacuation may be appropriate:

• When occupants are able to determine where aggressor(s) are located.
• When it is unsafe to stay in the building because of an imminent danger, fire, or structural damage.
• When the physical space does not allow for a reasonably effective lockdown.
• When locations outside are safer than inside.
• When the evacuation route does not expose the evacuees to danger.
• In situations where it is safe to evacuate from unaffected parts of the building or campus.

Plans should clearly identify routes, locations, and procedures and include provisions for those with access and functional needs. Drills that provide practice opportunities are important.
