A lockdown of campus buildings is an emergency procedure to secure and protect you in an immediate threat such as a violent intruder.
The lockdown procedure is used when it may be more dangerous to evacuate the building than to remain inside. By controlling entrances and exits, emergency personnel are better able to resolve a threat.
A lockdown alert may be issued through our public alert system, DC Alerts (text, email, voice messaging), campus security, floor wardens or a campus administrator.
For more detailed information on what to do during a lockdown on campus, watch our lockdown preparation video. The tutorial video on crash bar door locks is also helpful in case you need to lock a campus door from the inside.
