Step-by-Step: Using a First Aid Kit in an Emergency (UK)

Step Action Why It Matters
1. Stay Safe and Assess the Scene Check surroundings for danger (traffic, fire, electricity). Protect yourself first. Prevents additional injuries and ensures safe response.
2. Call for Help if Needed Dial 999 or 112 for emergencies. Ask bystanders for assistance. Professional help can guide you step by step until arrival.
3. Put On Protective Gloves Always use disposable gloves before touching blood or wounds. Prevents infection for both rescuer and casualty.
4. Identify the Type of Injury Look for bleeding, burns, fractures, or unconsciousness. Speak to the person if they’re awake. Helps you choose correct items from the kit quickly.
5. Use Appropriate Supplies Follow this quick guide:
  • Bleeding: Apply sterile gauze, firm pressure, and bandage.
  • Burns: Cool with water for 20 mins, apply burn gel dressing.
  • Eye injuries: Rinse gently with eye wash pod.
  • Sprains: Use cold pack, elevate limb, support with bandage.
6. Monitor and Reassure Keep the person comfortable and still. Cover lightly with a foil blanket if cold. Maintains body temperature and reduces shock.
7. Dispose of Used Items Safely Seal waste in disposable bag or wrap used dressings securely. Wash hands. Prevents contamination and keeps the kit hygienic for next use.
8. Restock and Record Replace any items used and log the incident if at work. Ensures readiness for future emergencies and compliance with HSE rules.

Quick Tips for First-Time Users

  • Open your kit once a year to familiarise yourself with where everything is.
  • Keep scissors, plasters, and gloves on top for easy access.
  • Store it in a cool, dry, and visible place.
  • Label it clearly — especially in shared homes or workplaces.

Common Mistakes to Avoid

  • ❌ Using items without checking expiry dates
  • ❌ Forgetting to wear gloves
  • ❌ Moving someone with a suspected neck or spine injury
  • ❌ Applying creams or ice directly to open wounds
  • ❌ Not restocking the kit after use

Be Prepared Before Emergencies Happen

Practice basic first aid skills and review your kit contents regularly. Every home, car, and workplace should have at least one complete first aid kit — ideally one that meets BS 8599 UK standards. For guidance, see our Home First Aid Kit Guide or Travel Checklist.
