If I found a crew mate unconscious on the floor, here's what I'd do:1. Call for help: Immediately alert others nearby and call the emergency contact number or security team to report the situation.2. Check for safety: Ensure the area is safe for both me and the unconscious person.3. Assess the situation: Check the person's airway, breathing, and circulation. If they're not breathing or have no pulse, I'd start CPR if trained.4. Provide first aid: If the person is breathing and has a pulse, I'd try to keep them comfortable and stable until medical help arrives.5. Stay with them: I'd stay with the person until medical professionals take over.6. Inform supervisor/management: Once the situation is under control, I'd inform my supervisor or management about the incident.Safety first, and getting medical help ASAP is key!
