What to do

1. First move away without increasing danger. Help only from somewhere safe.
2. Alert site security and police away from the aggressor.
3. Report injuries and request medical help.
4. Help only when it is safe to approach. For heavy bleeding, press the wound with a clean cloth. Do not press on an eye, a dented skull or organs protruding from the abdomen. Press around an embedded object or exposed bone. For an open chest wound or bleeding that will not stop, open the bleeding guide. Do not search inside the wound for a bullet or other object.
5. Only once safe: if unresponsive, call. If breathing is abnormal, start CPR with the dispatcher.
6. Once you are safe, ask someone you trust to stay with you, away from the attacker. Tell them where you are and whether you can move or speak. If danger returns, go to another safe place and report it. Do not wait to collect evidence.
7. Neck compression/suffocation: medical assessment now even no marks. Voice/swallow/breathing change, fainting/confusion: emergency now. No symptom waiting or neck massage.
