What should be done during the arrival and scene size-up?

• A. Park behind the vehicle and leave PPE in the ambulance.
• B. Position the ambulance to block traffic, wear PPE, and conduct a 360-degree walk around to identify hazards.
• C. Immediately enter the vehicle without assessing hazards.
• D. Only interview bystanders before assessing the scene.

Answer: (B)

Arriving at a vehicle crash requires prioritizing scene safety. The first steps are to position the ambulance to block traffic, don appropriate PPE, and perform a 360-degree walk-around to identify hazards. Blocking traffic creates a protected work zone for responders and patients, reducing the risk of secondary crashes and bystander interference. Wearing PPE guards you from common dangers at a crash scene—sharp edges, broken glass, chemical spills, fire, and moving components—while you assess the situation. The 360-degree survey is essential because hazards can be hidden from the initial vantage point: fuel leaks, downed electrical lines, fluids on the ground, unstable vehicle, spilled cargo, or hazards around patient access points. This walk-around also helps determine entry and exit routes, the need for additional resources, and potential hazards to bystanders. Without these steps, entering immediately without assessment exposes the team to unexpected dangers, and attempting to interview bystanders or leaving PPE behind does not establish the necessary safety posture or situational awareness.
