Do employees at your workplace know what to do if someone started shooting inside your building?
The Department of Homeland Security (DHS) has gathered materials with recommendations for businesses.
One booklet (PDF) gives advice on how to respond if an active shooter is in the vicinity, in order of preferred response:
1. Evacuate. Get out of the building. Employees should be familiar with multiple exit routes. Call 911 once you’re safely outside and away from the shooter.
