If there's immediate danger, call 911 or your local emergency number when it's safe to do so.

If you're worried someone may access your device, use a safer device or private way to look for help when possible.

Active-attacker incident

If there's an active-attacker incident.

Keep the first decision simple: leave if you can safely leave.

If you can safely get away from the danger, move away from it. If you can't safely leave, shelter. Contact 911 when it's safe to do so. Follow emergency personnel.

Official public guidance often uses the sequence Run, Hide, Fight: leave if you can do so safely; hide if you can't safely leave; and physical resistance is a last resort when there is immediate danger and no safer option. Leave Early does not teach physical confrontation.

Run / Move away if you can

If there's a safe path away from the danger, leave quickly.

  • Move away from the source of danger.
  • Use exits, doors, stairs, or another safe route if available.
  • Leave belongings behind if they make it harder to move.
  • Help others only if you can do so without putting yourself at greater risk.
  • Call or text 911 when you are safer and able to do so.
  • Keep moving until you are well away from the immediate area.

Hide / Shelter if you can't safely leave

If leaving isn't safe or possible, find a place that gives you more protection and makes it harder to be seen or reached.

  • Move out of view if possible.
  • Lock or block entry if it is safe and possible.
  • Silence phones and other noise sources if appropriate.
  • Keep quiet.
  • Keep an exit option in mind if possible.
  • Call or text 911 if you can do so safely.

If there is no safer option

Official guidance describes physical resistance as a last resort when there is immediate danger and you cannot safely run or hide.

  • Leave Early does not teach physical confrontation.
  • Focus on the safest useful action available to you.
  • Follow official emergency instructions.

When emergency personnel arrive

Follow their instructions.

  • Keep your hands empty and visible.
  • Avoid sudden movements toward responders.
  • Move where you are told to move.
  • Do not return until authorities say it is safe.

After you're safe

Contact someone you trust when you can. You may need medical, practical, emotional, workplace, school, or community support after a sudden emergency.

If your situation involves ongoing control, abuse, stalking, or barriers that make leaving unsafe or difficult, visit: When leaving isn't simple.
