Helping you make the right call when every second counts
Knowing when to dial 999 can be the difference between life and death. Whether you are a trained first aider or someone who is trying to help, acting quickly—and confidently—can make a huge impact. But not every medical situation calls for emergency services, so how do you know when it’s time to pick up the phone?
Let’s break it down into a simple, friendly guide that anyone can understand.
Recognising a True Emergency
You should call 999 immediately if someone is:
- Unconscious or not breathing
- Having chest pain or a suspected heart attack
- Showing signs of stroke (face drooping, arm weakness, slurred speech)
- Bleeding heavily that won’t stop
- Having a seizure for the first time or lasting too long
- Suffering a serious head injury
- In extreme pain after an accident or trauma
Remember the acronym DRABC from first aid training: Danger, Response, Airway, Breathing, Circulation. If any of these steps highlight a serious issue, it’s time to call.
Situations That Might Be Urgent
Some cases aren’t black and white. Ask yourself:
- Is the person safe until help arrives?
- Can I manage the situation with basic first aid?
- Would calling NHS 111 provide guidance?
If you’re unsure, err on the side of caution. Paramedics prefer false alarms over missed emergencies.
What Happens When You Call
When you dial 999, stay calm and be ready to give:
- Your exact location (What3words or landmarks help!)
- The person’s age and condition
- Any known medical history
- What treatment have you given
The operator will guide you through every step. You’re not alone.
First Aider’s Tip
Being prepared is half the battle. Learn basic first aid, keep emergency contacts saved on your phone, and know your address or postcode.
You might hope to never need this info—but when you do, you’ll be glad you did.
When in doubt, don’t hesitate. Calling 999 could save a life. And that’s the most important thing of all.
