Emergency response: how to act in the first vital minutes.
When someone collapses, chokes or bleeds heavily, the first few minutes decide the outcome. Learn the DRSABCD primary survey - the calm, step-by-step method trained first aiders use to assess any casualty, start CPR, use an AED and call 112 or 999 without panic.
A calm, systematic way to respond to any emergency.
DRSABCD keeps you focused under pressure so you treat the most life-threatening problems first and never miss a vital step.
- Check for Danger before you approach
- Check the casualty's Response
- Send for help - call 112 or 999
- Start CPR and use an AED if needed
What is the DRSABCD primary survey?
A clear, ordered approach that helps you assess any casualty safely and treat the most urgent problems first.
Danger
Check the scene is safe for you, the casualty and bystanders before you approach. Never become a second casualty.
Response
Check if the casualty responds to your voice and a gentle shake of the shoulders. No response means you must act fast.
Breathing
Open the airway by tilting the head and lifting the chin, then look, listen and feel for normal breathing for ten seconds.
CPR & AED
If breathing is absent or not normal, start CPR with 30 chest compressions and 2 rescue breaths, and use an AED as soon as it arrives.
Why fast, confident emergency response saves lives.
In a cardiac arrest, survival falls by around 10% for every minute that passes without CPR and defibrillation. An ambulance cannot always reach a casualty in those first few minutes - but a trained colleague can. That is why effective emergency response in the workplace is so important.
Most people freeze in an emergency because they are not sure what to do. The DRSABCD primary survey removes that uncertainty. It gives you a simple sequence to follow so you can stay calm, take control, and give the casualty the best possible chance until the emergency services arrive.
Emergencies you may need to respond to.
The same DRSABCD approach helps you take charge whatever the emergency in front of you.
Cardiac arrest
Recognise it fast, start high-quality CPR straight away, and use an AED the moment one is available.
Choking
Give up to five back blows between the shoulder blades, then abdominal thrusts, to clear a blocked airway.
Severe bleeding
Apply firm direct pressure, add dressings, and use a tourniquet for catastrophic limb bleeding.
Unconscious casualty
If they are breathing but unresponsive, place them in the recovery position and keep monitoring their breathing.
Shock and burns
Lay a casualty in shock down and keep them warm. Cool a burn under running water for at least 20 minutes.
Heart attack and stroke
Spot chest pain and the FAST signs of stroke early, reassure the casualty, and call 112 or 999 without delay.
A step-by-step guide to DRSABCD
D - Danger
Before you do anything, make sure the scene is safe. Look for traffic, electricity, fire, chemicals, machinery or anything that could harm you, the casualty or bystanders.
- Switch off or isolate any obvious hazard if it is safe to do so.
- Do not put yourself at risk - you cannot help if you become a casualty too.
- Only move the casualty if leaving them puts them in greater danger.
- Protect yourself with gloves if they are available.
R - Response
Check whether the casualty responds. Speak clearly and gently shake their shoulders, asking a simple question such as "Can you hear me?".
- If they respond, reassure them and find out what is wrong.
- If there is no response, they need urgent help - move quickly to the next steps.
- Shout for assistance from anyone nearby.
S - Send for help
Call 112 or 999, or have a bystander call while you stay with the casualty. Ask someone to fetch the nearest AED.
- If you are alone, put your phone on speaker so you can give first aid while you talk.
- Give a clear location and a brief description of what has happened.
- Do not hang up until the call handler tells you to.
A - Airway
Open the airway by gently tilting the head back and lifting the chin. Look inside the mouth and remove any obvious obstruction you can see.
B - Breathing
Look, listen and feel for normal breathing for up to ten seconds. Occasional gasps are not normal breathing and you should treat the casualty as not breathing.
Remember: if the casualty is not breathing normally, do not wait. Begin CPR immediately - early CPR and defibrillation give the best chance of survival.
C - CPR
Give 30 chest compressions in the centre of the chest, pushing hard and fast to a depth of 5 to 6 cm at about 100 to 120 per minute, followed by 2 rescue breaths. Keep the cycle going without stopping until help takes over.
D - Defibrillation
Attach an AED as soon as one arrives and follow the spoken prompts exactly. Modern AEDs are safe and will only advise a shock if one is needed.
After the emergency
Once the emergency services take over, your job is not quite finished:
- Hand over clearly - explain what happened, the casualty's condition, and any first aid you gave.
- Record the incident - complete an incident report while the details are fresh.
- Check your first aid kit - restock anything you used so it is ready for next time.
- Look after yourself - responding to an emergency can be stressful, so talk it through afterwards.
