Lockdown

Updated 8/4/25

Before a Lockdown

Become familiar with Aerospace lockdown procedures. Please note the following:

  • The EMC and/or Security will decide when to initiate lockdown.
  • This may include deactivating badges, badge readers, shutting down gate operations, and more.
  • Employees may be notified of lockdown by an AeroElert, PA system, and/or verbally.
  • Communication will occur when it is safe to do so.

During a Lockdown

  • If you are in an office or conference room, stay there, secure the door and windows, and await further instructions from Security or emergency personnel. 
  • If you are in a corridor, go into the closest available office. 
  • If the door does not lock, barricade the door with furniture. 
  • Close blinds where possible. 
  • Stay away from windows and doors. 
  • Stay low and quiet. 
  • Cell phones should be put on quiet or vibrate mode. Do not make non-essential calls. 
  • Follow instructions from Security, law enforcement or emergency personnel only. 
  • During a lockdown, remain where you are and await further instructions even if the fire alarm is activated. 
  • For their own safety, emergency personnel must initially consider all individuals as potential threats. Always follow instructions from police to avoid harm and ensure the best possible response. 
  • If in a SCIF, spin external dial and close doors between SCIFs, if possible and safe to do so. 

Actions to Avoid

  • Do not open the door once it has been secured until you receive an “all clear” or are certain from emergency response personnel. 
  • Do not use or hide in restrooms. 
  • Do not travel down long corridors. 
  • Do not assemble in large open areas. 
  • Do not call 911 unless you have immediate concern for your safety, the safety of others, or feel you have critical information that will assist emergency personnel in the response.

After a Lockdown

  • Cooperate with Security, law enforcement, or emergency personnel to assist in an orderly evacuation. 
  • Proceed to the designated assembly area if advised. 
  • The police may require individuals to remain available for questioning following a lockdown. 

NOTE: Security staff may be present as you exit the building to provide additional information.
