The Scene Survey

Analyzing the Scene for Potential Hazards

When you arrive at an emergency scene, your first task is to quickly but thoroughly assess the area for any potential hazards. This step is crucial for ensuring your safety, the casualty’s safety, and that of any bystanders.

  • Types of Hazards to Look For:
    • Environmental Hazards: Wet floors, uneven surfaces, or extreme weather conditions.
    • Traffic Hazards: In road accidents, be aware of oncoming vehicles.
    • Chemical or Fire Hazards: Spills, leaks, or flames, especially in industrial or kitchen accidents.
    • Electrical Hazards: Exposed wires or electrical equipment, particularly in cases of electrical injuries.
    • Violence or Security Risks: Signs of aggression or threat from individuals at the scene.
  • Example Scenario:
    • You arrive at a workplace where someone has fallen from a ladder. Before rushing to the casualty, you quickly scan the area: Are there any spilled liquids? Is the ladder securely positioned? Is there any equipment that could fall or cause injury?

Safe Approach Techniques to the Casualty

Once you have assessed the scene and deemed it safe, your next step is to approach the casualty. This approach should be done carefully, keeping in mind any potential risks that might not have been immediately obvious.

  • Approach Techniques:
    • Approach from a Safe Angle: Always approach in a way that allows you to see and avoid potential hazards.
    • Use of PPE: Where necessary, use gloves, masks, or eye protection, especially if there’s a risk of bodily fluids or hazardous materials.
    • Stay Alert: As you approach, continue to assess the situation. Be prepared to stop or retreat if you identify new hazards.
  • Example Scenario:
    • In a car accident on a busy road, approach the vehicle from the sidewalk, not the road, to avoid traffic. If the car is smoking, stay at a safe distance and call for emergency services.

The Primary Survey (DR ABC)

The Primary Survey is a quick method for assessing the most important life-threatening conditions in a casualty. It follows the DRABC acronym: Danger, Response, Airway, Breathing, and Circulation. Let’s delve into each element with detailed explanations and examples.

D – Danger

Objective: Ensure the area is safe for both you and the casualty.

  • Actions: Look out for any ongoing risks such as traffic, fire, or hazardous materials. If the scene is unsafe, take necessary steps to make it safe if possible, or move the casualty to a safer location.
  • Example:
    • Car Accident: Before approaching the vehicle, check for leaking fuel or the risk of fire. If it’s unsafe, wait for emergency services to secure the scene.

R – Response

Objective: Check if the casualty is responsive.

  • Actions: Gently shake the casualty’s shoulders and ask loudly, “Are you okay?” Look for any response, such as movement, sounds, or opening of eyes.
  • Example:
    • Unconscious Person in a Park: If they don’t respond to your voice or touch, they are unresponsive, and you need to proceed with the next steps of the primary survey.

A – Airway

Objective: Ensure the casualty’s airway is clear.

  • Actions: If the casualty is unresponsive, tilt their head back and lift their chin to open the airway. Check for any blockage in the mouth or throat. If there’s visible obstruction, remove it if you can safely do so.
  • Example:
    • Choking Incident: If the casualty is unconscious, open their mouth and look for any obstruction. If you see an object blocking the airway, carefully remove it.

B – Breathing

Objective: Check if the casualty is breathing normally.

  • Actions: Once the airway is open, lean close to the casualty’s mouth and nose. Look for chest movements, listen for breathing sounds, and feel for breath on your cheek for up to 10 seconds.
  • Example:
    • Cardiac Arrest: If there’s no normal breathing, this could indicate cardiac arrest. You would then need to start CPR immediately.

C – Circulation

Objective: Check for signs of severe bleeding.

  • Actions: Look over the casualty’s body for any signs of significant blood loss. If you find severe bleeding, it needs to be controlled immediately, even before starting CPR.
  • Example:
    • Workplace Accident: If the casualty has a deep cut with profuse bleeding, apply direct pressure to the wound to control the bleeding.

In summary, the Primary Survey (DRABC) is a systematic approach to quickly identify life-threatening conditions and take immediate action. Each step must be performed swiftly and methodically to ensure the casualty receives the necessary care as quickly as possible. This process is crucial in determining the severity of the situation and prioritizing your actions as a first aider.

Summoning Assisstance

After conducting the Primary Survey (DRABC), the next critical step is summoning assistance. This involves deciding when and how to call for emergency services or seek additional help. This section will cover the importance of getting appropriate help and the key considerations in doing so, illustrated with examples.

Recognizing Your Own Limitations

  • Objective: Understand when the situation is beyond your first aid capabilities and requires professional medical assistance.
  • Actions: Evaluate the severity of the casualty’s condition. If it’s severe or life-threatening, or if you’re unsure of how to proceed, it’s time to call for help.
  • Example:
    • Suspected Heart Attack: If you encounter someone experiencing chest pain, shortness of breath, and nausea, these could be signs of a heart attack. Even if you’re trained in first aid, this situation requires immediate professional medical attention.

Determining What Help is Needed

  • Objective: Assess the type of assistance required based on the casualty’s condition.
  • Actions: Decide whether to call an ambulance, seek help from bystanders, or contact specific emergency services like the fire department.
  • Example:
    • Road Traffic Collision: If there are multiple casualties or potential hazards like fire, you may need to call both ambulance and fire services.

Bystander Assistance

  • Objective: Utilize the help of bystanders effectively in an emergency.
  • Actions: Instruct bystanders to call emergency services, fetch first aid kits, or help with crowd control.
  • Example:
    • Public Place Incident: In a busy area, ask a bystander to call 911/112/999 while you attend to the casualty. Another bystander could be asked to direct the emergency services to your location.

Speakerphone Option

  • Objective: Maintain continuous care for the casualty while contacting emergency services.
  • Actions: Use the speakerphone function on your phone to talk to emergency responders without leaving the casualty’s side.
  • Example:
    • Lone Responder Scenario: If you’re alone with the casualty, use the speakerphone to communicate with the emergency dispatcher while you provide first aid.

Emergency Numbers and Information

  • Objective: Know which number to call and what information to provide.
  • Actions: In most locations, 911, 112, or 999 will connect you to emergency services. Be ready to provide specific information about the location, nature of the emergency, and the condition of the casualty.
  • Example:
    • Workplace Emergency: Call the relevant emergency number and provide clear details – “There’s been a fall at [Address]. One person is unconscious. We need an ambulance.”

Alternative Helplines

  • Objective: Be aware of other helplines for non-life-threatening situations.
  • Actions: In cases where immediate emergency services are not needed, but medical advice is required, use national helplines like NHS 111 in the UK.
  • Example:
    • Uncertain Medical Situations: If someone is experiencing unusual but not immediately life-threatening symptoms, and you’re unsure of the best course of action, call a helpline for guidance.

Summoning appropriate assistance is a vital part of a first aider’s role. It involves making quick decisions based on the casualty’s condition, utilizing available resources, and communicating effectively with emergency services. This step ensures that the casualty receives the most appropriate care as quickly as possible.
