What to do

1. Noise alone does not establish violence. Calls for help or immediate danger: emergency help. Otherwise use a local nonurgent channel. Stay out rather than investigate.
2. Calls for help or possible violence: call from protection. Say what you heard, where from and when. Do not claim a cause you did not see.
3. During a weapons attack: escape only by a safe route. If unable, hide, secure the door and silence your phone. Call when safe.
4. Threat or immediate danger: call emergency services. Without immediate danger: use the local non-urgent channel.
5. Wait somewhere protected. Report if unable to leave or speak. Without a phone, ask someone to call from safety. Report changing danger.
6. If hearing is limited, report only what you observed. Ask for communication help. Do not rely on an unverified messaging channel for dispatch.
