In the ACECARD sequence, what is the correct expansion?

• A. Approach, Caution signs, Examine the scene, Casualties, Ambulance, fire and rescue, Remove obstructions, Detailed investigation
• B. Approach, Caution signs, Assess the scene, Casualties, Ambulance, Fire and Rescue, Remove obstructions, Detailed investigation
• C. Approach, Caution, Examine, Casualties, Ambulance, Fire and Rescue, Remove obstructions, Detailed investigation
• D. Approach, Check signs, Examine the scene, Casualties, Ambulance, Fire and Rescue, Remove obstructions, Detailed investigation

Answer: (A)

The main idea being tested is the prioritization and exact wording of the ACECARD actions at an incident scene, focusing on ensuring safety first and then progressing through medical and investigative tasks in the correct order. The expansion that fits best is Approach, Caution signs, Examine the scene, Casualties, Ambulance, Fire and Rescue, Remove obstructions, Detailed investigation.

Starting with Approach and then Caution signs emphasizes safety: you must reach and assess the scene while actively warning others to prevent further harm or interference. Then you Examine the scene to identify hazards, vehicle positions, fuel leaks, safety risks, and any evidence you’ll need to consider later. Next come Casualties, ensuring those injured receive immediate attention, followed by calling or coordinating an Ambulance to provide medical care. Fire and Rescue would be involved if there’s a fire risk, hazardous materials, or if extrication is required. After stabilizing safety and medical needs, Remove obstructions to create safe access and prevent contamination of the scene or evidence. Finally, Detailed investigation is carried out to document conditions, collect evidence, and understand what happened for reporting and legal purposes.

The other options rely on slightly different wording or omit the explicit warning signs, which weakens the established sequence. For example, using Assess the scene or Check signs changes the standard phrasing and emphasis, while missing “Caution signs” can downplay the safety-focused step before examining the scene.
