Difficulty: Very hardSecuring and Managing an Accident Scene

You are the first to arrive at the scene of a serious collision on a motorway at night. A car and a motorcycle are involved. There is a strong smell of unburnt fuel, the car driver is trapped but conscious, and the motorcyclist is lying motionless on the verge. Which of the following actions MUST you take to manage the scene safely?

  1. Instruct everyone to extinguish cigarettes and ensure all vehicle engines at the scene are switched off.Answer
  2. B
    Walk back to place a warning triangle at least 45 metres behind the incident to alert fast-approaching traffic.
  3. Leave the motorcyclist in their current position and do not attempt to move them unless they are in immediate, life-threatening danger.Answer
  4. D
    Carefully remove the motorcyclist's crash helmet to accurately assess their airway and monitor their breathing.

Answer

You must ensure all vehicle engines are switched off and cigarettes are extinguished to neutralize the fire risk, and you must leave casualties exactly where they are unless they face an immediate, life-threatening danger.
Securing the scene safely requires neutralizing the immediate fire hazard by turning off engines and enforcing a strict no-smoking rule. Furthermore, to prevent causing severe secondary injuries (such as spinal cord damage), casualties must be left in their current position unless they face an immediate, life-threatening danger (like an active fire).

Step-by-Step Solution

1
Assess the immediate hazards upon arriving at the scene.
Identify the strong smell of unburnt fuel as a critical and immediate fire risk.
Scene safety is always the first priority to prevent the situation from deteriorating and causing further casualties.
2
Mitigate the identified fire risk.
Switch off the engines of any involved vehicles and ensure no one is smoking nearby.
Spilled fuel can easily ignite from a hot exhaust, electrical spark, or a discarded cigarette.
3
Evaluate the condition of the casualties.
Recognize that both the trapped driver and the motionless motorcyclist have potentially suffered severe trauma.
A high-speed motorway collision carries a significant risk of spinal and neck injuries.
4
Apply the principles of basic casualty management.
Decide to leave the casualties in their current positions, providing verbal reassurance only.
Moving a casualty, or removing a crash helmet, can exacerbate spinal injuries. They should only be moved if there is an immediate, unavoidable danger such as an active fire.

Key Concept

Securing an accident scene involves neutralizing immediate hazards (like fire risks) and strictly avoiding actions that could worsen casualties' injuries (like moving them unnecessarily or using inappropriate warning devices on motorways).
