The very first thing EMTs must do when they arrive on the scene is:

• A. Survey the entire area for possible hazards.
• B. Start treatment immediately.
• C. Wait for back-up.
• D. Check equipment.

Answer: (A)

Scene safety is the top priority. When EMTs arrive, they perform a scene size-up to identify hazards and make sure the environment is safe before approaching patients. This protects you, your partner, bystanders, and patients from additional harm and ensures you can provide care without being impeded by dangers like fire, traffic, downed power lines, or hazardous materials. Once the scene is deemed safe, you can proceed with the patient assessment and care. Jumping straight into treatment or waiting for back-up without first confirming safety can put everyone at risk, and checking equipment too early won’t address immediate hazards.
