In short

First aid is the help you give before professional help arrives. In the UK, call 999 if life is at risk. Check for danger, get a response, open the airway and look for normal breathing. This page is a free written guide. It is not a first aid course.

How to give first aid in an emergency?

  1. 1

    Check for danger

    Look after your own safety first. Do not approach if the scene is unsafe. Call 999 and wait if you are not sure.

  2. 2

    Check for a response

    Speak loudly and tap the collarbones. If there is no response, shout for help.

  3. 3

    Call 999

    Use speakerphone if you are alone. Tell the handler where you are and what you can see. Stay on the line.

  4. 4

    Open the airway

    Tilt the head back and lift the chin. Do not put your fingers in the mouth.

  5. 5

    Check breathing

    Look, listen and feel for normal breathing for up to ten seconds. Occasional gasps are not normal breathing.

  6. 6

    Start CPR if needed

    If they are not breathing normally, start chest compressions. Use an AED as soon as one arrives and follow the voice prompts.

What is first aid?

First aid is the immediate help you give when someone is ill or injured, before a paramedic or doctor takes over. It can be as simple as calling 999, applying pressure to a wound, or starting CPR. You do not need a certificate to help. Stay safe, get help early, and follow the call handler.

Most first aid is not dramatic. It is noticing that someone has collapsed, making the area safe, and staying with them until help arrives. The 999 handler can talk you through the next step. That is first aid too.

This page is a written guide for people in the United Kingdom. It is not a first aid course, an app, or an accredited qualification. World Aid Network does not train first aiders. For a course or workshop, use the British Red Cross, St John Ambulance or another recognised trainer.

What should I do first in an emergency?

Protect yourself, then the person. Check for danger, then for a response. If they do not respond, shout for help and call 999. Open the airway and look for normal breathing for up to ten seconds. If they are not breathing normally, start CPR and send someone for a defibrillator.

Trainers often teach this as DRSABC: Danger, Response, Send for help, Airway, Breathing, CPR. The order matters. You cannot help if you become a second casualty. If the scene is not safe, stay back and call 999.

Use speakerphone so you can keep your hands free. The handler will ask where you are. Give a road name, a postcode, a shop, or a landmark. If you are not sure, they can often locate a mobile call.

  • · Danger — look for traffic, electricity, fire, water, or an aggressive dog
  • · Response — speak and tap; do not shake a baby
  • · Send for help — call 999; send someone for an AED if one is nearby
  • · Airway — head tilt and chin lift; do not sweep the mouth blindly
  • · Breathing — look, listen and feel for up to ten seconds
  • · CPR — start if breathing is absent or not normal

When should I call 999?

Call 999 if you think someone’s life is at risk. That includes being unresponsive, not breathing normally, choking badly, bleeding heavily, a suspected stroke or heart attack, a seizure that will not stop, or a severe allergic reaction. If you are not sure, call NHS 111. Calling 999 does not always mean an ambulance is sent.

NHS 111 can tell you whether you need 999, A&E, a same-day GP slot, or self-care. For a child under five, call 111 if you need advice and it is not obviously life-threatening.

Stay on the line. Call again if the person’s condition changes or if you have to move. Lock pets away if you can. Collect medicines and GP details if it is safe to do so. Turn lights on so the crew can find you.

How do I help someone who is bleeding?

Apply firm, direct pressure with a clean cloth or dressing and keep it there. Call 999 for heavy bleeding. If something is stuck in the wound, leave it in and press around it, not on it. If blood soaks through, add another layer. Do not peel the first dressing off.

Sit or lie the person down if you can. Raise the injured part only if it does not cause more pain and there is no suspected break. Wear gloves if you have them. Wash your hands after.

Do not use a tourniquet unless you have been trained to do so. The 999 handler can tell you what to do next. Keep talking to the person so you know if they become drowsy or unresponsive.

How do I treat a burn?

Cool the burn under cool running water for twenty minutes. Remove rings, watches and tight clothing if they will come off easily. Cover loosely with cling film or a clean plastic bag. Do not use ice, butter, toothpaste or cream. Call 999 for large, chemical or electrical burns, or if the face, hands, feet or genitals are involved.

Cooling takes the heat out of the skin and reduces damage. Twenty minutes is longer than most people think. Use cool tap water, not ice, which can freeze the tissue. Keep the rest of the person warm so they do not get cold while you cool the burn.

Chemical burns need the chemical removed first — brush off dry powder, then rinse. Electrical burns can hide deeper injury. Call 999. For a baby or a burn bigger than the person’s hand, get urgent medical help.

How do I help someone who is choking?

If they can cough, encourage them to keep coughing. If they cannot cough, speak or breathe, give up to five sharp back blows between the shoulder blades. If that fails, give up to five abdominal thrusts. Call 999. Keep alternating until the blockage clears or they become unresponsive, then start CPR.

Do not put your fingers in their mouth to fish for the object. You can push it further down. Stand slightly to the side for back blows. For abdominal thrusts, stand behind, make a fist above the navel, and pull inwards and upwards.

Babies are different. Do not give abdominal thrusts to an infant. Call 999. The handler will talk you through back blows and chest thrusts with the baby face down, then face up, along your forearm. If they become unresponsive, start CPR for a baby as the handler directs.

How do I give CPR?

If an adult is unresponsive and not breathing normally, call 999 and start chest compressions. Push hard and fast in the centre of the chest, five to six centimetres deep, at 100 to 120 times a minute. If you can, give 30 compressions then two rescue breaths. Hands-only CPR is still useful if you cannot give breaths.

Kneel beside them. Place the heel of one hand on the centre of the chest, the other hand on top, and interlock the fingers. Keep your arms straight. Let the chest come back up between compressions. Continue until help takes over, they start breathing normally, or you are too exhausted to go on.

Send someone for a public defibrillator (AED). Switch it on and follow the voice prompts. Do not stop compressions for longer than you must. The 999 handler can count with you. For children and babies the technique changes — stay on the line and they will talk you through it.

What is the recovery position?

Use the recovery position if someone is unresponsive but breathing normally. It keeps the airway open and lets vomit drain. Roll them onto their side, tilt the head back, and bend the top leg. Call 999. Stay with them and check breathing often. Do not use it if you suspect a spinal injury unless you must leave them.

Kneel beside them. Place the arm nearest you at a right angle. Bring the far arm across the chest and hold the back of that hand against the cheek. Bend the far knee, then roll them towards you. Tilt the head to keep the airway open.

If they stop breathing normally, roll them onto their back and start CPR. Tell the 999 handler what you have done.

What should be in a first aid kit?

A home first aid kit is dressings, plasters, disposable gloves, a triangular bandage, scissors, tweezers, a foil blanket and a face shield for rescue breaths. Keep cling film for burns. Check dates. This is not a hospital. Call 999 for anything that looks life-threatening rather than rummaging for the perfect item.

You can give useful first aid with almost nothing: your hands for pressure, a clean t-shirt as a pad, a phone on speaker. A kit just makes that easier. Store it where everyone in the house can find it, not locked in a shed.

World Aid Network does not sell first aid kits. After a disaster overseas, local partners may buy dressings, soap and clean water for families who have lost their homes. That sits on our emergency relief pages. It is not this guide, and it is not a UK first aid kit posted from Britain.

Where can I learn first aid in the UK?

Book a course or a free workshop with a recognised trainer. The British Red Cross teaches first aid and has a free first aid app. St John Ambulance and St Andrew’s First Aid also train the public. This page cannot replace practice on a manikin or feedback from an instructor. World Aid Network does not run first aid courses.

A short written guide helps you remember the order: danger, response, 999, airway, breathing, CPR. It will not make you an accredited first aider. If you want a certificate for work, you need a paid, assessed course.

British Red Cross first aid: https://www.redcross.org.uk/first-aid. St John Ambulance: https://www.sja.org.uk. NHS 999 and 111 remain the right numbers in an emergency, whether or not you have trained.

Is this the British Red Cross first aid page?

No. The British Red Cross teaches first aid skills, runs workshops and has a first aid app. This is World Aid Network’s free written First Aid guide. We do not accredit a qualification. Use the Red Cross for a UK course. Use this page as a reminder of what to do.

Both jobs matter. One organisation trains millions of people and sells kits. We publish this guide so someone searching for First Aid can see the first steps in British English, then we send them to 999, NHS 111, and a proper trainer. We do not pretend to be the Red Cross.

Do you run a first aid course?

No. World Aid Network does not run first aid courses, workshops or a first aid app. This page is general information, not a qualification. Wrong first aid can cause harm, which is why we tell you to follow the 999 handler. For skills you can practise, book a recognised UK trainer such as the British Red Cross.

We will not guess at timings you should only learn with an instructor standing over a manikin. If the 999 handler’s instructions differ from this page, follow the handler. They can see the incident in real time. We cannot.

Is First Aid one of your emergency appeals?

No. First Aid on this site is a skills guide, not a fundraising appeal. World Aid Network’s disaster gifts fund food, clean water, hygiene kits and temporary shelter in Pakistan, Indonesia and Malaysia. Those sit on the emergency relief and appeals pages. Do not look here to donate to a first aid fund. There isn’t one.

If you searched for First Aid because someone in front of you needs help, stay on this page and call 999 if life is at risk. If you searched because you want to fund disaster relief overseas, open emergency relief or a named appeal. Those are different jobs.
