Dealing with the traces of a fight in a public place quickly requires care and speed to ensure safety and minimize the impact. Here are some steps: 1. **Confirm safety**: First make sure there is no danger of continuing at the scene to avoid further harm to yourself or others. 2. **Call the police for help**: Depending on the severity of the incident, it is crucial to call the police or emergency services in time. They can provide professional help and formally handle the incident. 3. **Assess the injuries**: If someone is injured, give priority to treating the injured. Perform first aid, such as stopping bleeding and bandaging, until professional medical personnel arrive. 4. **Protect the scene**: Try not to touch the scene until the police arrive. If you must clean up, try to avoid destroying evidence, especially if it involves a crime. 5. **Clean up the scene**: - If there is liquid (such as blood) on the ground, use absorbent materials (such as paper towels, rags) to absorb as much as possible. - Use appropriate detergents to wash the surface to remove stains and disinfect with disinfectants. - If there are broken items, carefully collect the fragments to avoid hurting yourself or others. 6. **Calm the onlookers**: You can properly inform the onlookers that the situation has been controlled to avoid panic or the spread of false information. 7. **Record the situation**: When it is safe, record the details of the incident you witnessed to facilitate subsequent investigation. 8. **Psychological counseling**: If any witnesses or participants feel uneasy, provide psychological comfort and suggest seeking professional psychological help. It is important that safety and legal and compliant actions should be the top priority in any situation.
