What is the first priority when arriving on a casualty scene?

• A. Document the scene.
• B. Wait for additional medics before acting.
• C. Immediately begin airway management.
• D. Ensure scene safety for yourself, the casualty, and bystanders; assess threats; then begin treatment.

Answer: (D)

The main idea here is that safety comes first at a casualty scene. Before you do anything to help, you must ensure the scene is safe for you, the casualty, and bystanders. Quickly scan for hazards like fire, moving traffic, unstable structures, weapons, or hazardous substances, and establish a safe approach or call for help if needed. If there are ongoing threats, address or mitigate them and wait only as necessary for security or additional resources. Once the environment is safe, you can assess the casualty and begin treatment, starting with the most life-threatening needs. Documentation or waiting for more medics before acting would delay care, and attempting airway management without first ensuring safety risks everyone’s well-being.
