If you’re training for OFA Level 3 in Vancouver, you already know that first aid is about more than just bandages and CPR. As an Occupational First Aid Level 3 attendant, your first responsibility in any emergency isn’t to rush in—it’s to assess the scene. This crucial step ensures your safety, the patient’s safety, and a smooth response to the incident.
A proper scene assessment helps you figure out what happened, spot potential hazards, and decide your next move. In this guide, we’ll break down the scene assessment process step by step so you can handle emergencies confidently and efficiently.
Why is a Scene Assessment So Important?
When responding to an emergency, your first few moments on the scene are critical. Rushing in without assessing the environment could put you and others at risk. A solid scene assessment helps you:
✅ Ensure safety – Identify hazards and take steps to control them.
✅ Understand the incident – Figure out what happened and what injuries you might be dealing with.
✅ Determine the number of patients – Know how many people need help.
✅ Make transport decisions – Decide if rapid transport to a medical facility is needed.
✅ Prioritize your actions – Focus on urgent tasks rather than scrambling to figure things out.
In OFA Level 3 training in Vancouver, scene assessment is the foundation of first aid response. Mastering this skill ensures you’re ready for real-life emergencies.
The Four Stages of the Priority Action Approach
In OFA Level 3, we follow a priority action approach, which consists of four key steps:
1️⃣ Scene Assessment – Identifying hazards, understanding what happened, and ensuring safety.
2️⃣ Primary Survey – Checking for life-threatening conditions and providing critical interventions.
3️⃣ Transport Decision – Deciding whether the patient needs immediate transport.
4️⃣ Secondary Survey – Conducting a detailed head-to-toe assessment.
The scene assessment is the first and most essential step—so let’s break it down.
Step-by-Step Guide to a Scene Assessment
1. Scan for Hazards
Before approaching the patient, take a moment to scan the environment. Ask yourself:
⚠️ Is there anything that could be dangerous?
- Moving vehicles or machinery?
- Chemical spills, fire, or electrical hazards?
- Unstable ground, falling debris, or other physical dangers?
- Bloodborne pathogens or other biological risks?
👉 If hazards exist, control or remove them first. This could mean turning off equipment, blocking traffic, using personal protective equipment (PPE), or calling for additional resources. Your safety always comes first!
2. Determine the Mechanism of Injury (MOI) or Nature of Illness
Once you know the scene is safe, figure out what happened. The mechanism of injury (MOI) helps you predict what kind of injuries the patient might have.
Ask yourself:
🛑 What happened? – Was it a fall? A machinery accident? A hazardous material exposure?
🕒 When did it happen? – How long ago was the injury or illness?
💥 How much force was involved? – Was it a minor bump or a major impact?
Observing clues at the scene—like broken equipment, bloodstains, or a patient’s position—can help fill in the gaps.
🔎 For walk-in patients: The approach is slightly different. Watch how they move and listen to what they say as they enter the first aid room. Are they struggling to breathe? Holding an injured limb? Turning pale? These are immediate red flags.
3. Determine the Number of Patients
If you’re responding to a workplace incident, there could be multiple casualties. Do a quick scan of the area to see if there are other workers who need help.
🚑 If multiple people are injured, you may need to use the START triage system to prioritize care. This is especially crucial in mass casualty incidents where time and resources are limited.
4. Make Initial Transport Decisions
As a certified OFA Level 3 attendant in Vancouver, you need to determine whether a patient requires immediate transport to a higher level of care.
📌 Red flags for rapid transport include:
- Complete or persistent airway obstruction
- Severe crush injuries
- Smoke or toxic gas inhalation
- Carbon monoxide poisoning
- Electrical injuries
- Near drowning incidents
If any of these conditions are present, prepare for urgent transport and ensure appropriate spinal precautions if needed.
Additional Considerations for Scene Assessment
💬 Communication is Key
- Speak clearly with the patient and any bystanders.
- Reassure them that you are trained and there to help.
📝 Documentation Matters
- Record key details of the scene, hazards, and initial findings. This will be important for your first aid report.
⚖️ Triage in Mass Casualty Situations
- In larger incidents, use the RPM (Respiratory, Perfusion, Mental Status) method to quickly assess patients.
How Scene Assessment Differs for Walk-in Patients
If you’re working in a first aid room at a worksite, the scene assessment is modified slightly. Instead of scanning a dangerous scene, you:
👀 Observe the patient as they enter – Do they appear pale, short of breath, or in obvious distress?
❓ Ask about the mechanism of injury – If they’re limping or cradling an arm, find out what happened.
🛏️ Decide their position – If they look unwell, move them to a supine (lying down) position and start a primary survey immediately.
In OFA Level 3 courses in Vancouver, you’ll practice both emergency scene assessments and how to evaluate walk-in patients in a first aid setting.
