Accidents and emergencies can happen anywhere, and knowing the right English words can help you understand a situation, call for help and explain what is wrong. Words like first aider, sprain and bandage appear in safety notices, on medicine packets and during a 999 call, so they are well worth learning.

This guide walks through the key English first aid vocabulary by theme — the people and places involved, common injuries, symptoms, the items in a first-aid kit, and the actions used to treat someone. Each term comes with a definition and an example sentence, and everything uses standard British English.

Important — please read

This article teaches vocabulary only. It is not medical advice and does not qualify you to treat injuries. In a real emergency in the UK, call 999 straight away, and to learn the skills properly, take a certified first-aid course with an organisation such as the British Red Cross or St John Ambulance.

Key Takeaways

  • In the UK you call 999 (or 112) for the emergency services, not 911.
  • The hospital department for emergencies is A&E (Accident and Emergency), not the ER.
  • A small cut is covered with a plaster; a larger wound is wrapped with a bandage.
  • A sprain injures a ligament; a fracture is a broken bone.
  • CPR and the recovery position are key skills — learn them on a certified course.

People and Places

First, the people who help in an emergency and the places where casualties are treated.

British vs American

In the UK you call 999 (the free number 112 also works), and the hospital emergency department is A&E. In the United States the emergency number is 911 and the department is the ER (Emergency Room). Use the British terms when you are in the UK.

Useful Phrases in an Emergency

Vocabulary is most useful inside real phrases. Here are natural sentences for calling for help and for comforting a casualty.

On a 999 call

  • I need an ambulance, please.
  • There has been an accident.
  • The address is… / We are at…
  • He is unconscious but breathing.
  • She is not breathing — please hurry.

Reassuring a casualty

  • Try to stay calm — help is on the way.
  • Can you tell me your name?
  • Where does it hurt?
  • Stay still and don’t move.
  • I’m going to put pressure on the wound.

Put a plaster on the small cut and a bandage on the larger wound.

If the casualty is unconscious but breathing, place them in the recovery position.

Cool a burn or scald under running water and call an ambulance if it is serious.

Collocation Tip

Learn words in their natural partners: you call an ambulance, apply pressure to a wound, clean the wound, dress a wound, put on a plaster, and place someone in the recovery position. Memorising these phrases is faster than learning each word alone.

Frequently Asked Questions

In the United Kingdom you dial 999 for the emergency services — ambulance, police, fire or coastguard. The free number 112 also works across the UK and the rest of Europe. For urgent but non-life-threatening medical advice in England, you can call 111 (NHS 111) instead. Remember that 911 is the American emergency number and does not work in the UK.

They mean the same kind of place, but the words differ by country. In British English, the hospital department for serious injuries and emergencies is A&E, which stands for Accident and Emergency (sometimes called Casualty). In American English, the same department is the ER, or Emergency Room. So a British speaker would say, ‘We took him to A&E,’ while an American would say, ‘We took him to the ER.’

A plaster is a small, sticky strip used to cover a minor cut or graze; in American English it is called a Band-Aid or adhesive bandage. A bandage is a longer strip of material, often rolled, used to wrap and support a larger wound, sprain or dressing. In short, you put a plaster on a small cut and wrap a bandage around a bigger injury.

The recovery position is a safe position you place an unconscious but breathing casualty in, lying on their side with the head tilted slightly back. It helps keep the airway open and allows fluids to drain from the mouth so the person does not choke. It is one of the most important first-aid skills, but you should learn it properly on a certified course rather than from a single description.

CPR stands for cardiopulmonary resuscitation. It is an emergency procedure that combines chest compressions with rescue breaths to keep blood and oxygen moving around the body when someone’s heart has stopped. CPR can save a life while you wait for an ambulance, but it must be performed correctly, so it is essential to learn it on a hands-on certified first-aid course.

A sprain is an injury to a ligament (the tissue that connects bones) caused by twisting or stretching a joint, often the ankle or wrist. A fracture is a broken bone. A sprain usually causes pain, swelling and bruising but the bone is intact, whereas a fracture means the bone itself is cracked or broken. Severe pain, an odd shape or being unable to use the limb may suggest a fracture, which needs medical assessment.

Both damage the skin with heat, but the cause differs. A burn is caused by dry heat, such as fire, a hot iron or the sun. A scald is caused by wet heat, such as boiling water, hot tea or steam. The first aid is similar: cool the area under cool running water for at least twenty minutes and do not apply creams or ice. Seek medical help for large or deep burns and scalds.

A first aider is a person trained to give immediate, basic help to someone who is injured or suddenly unwell, until professional medical help arrives. Many workplaces are required to have a qualified first aider on site. A first aider is not a doctor or paramedic, but their early actions — such as stopping bleeding or placing a casualty in the recovery position — can make a real difference.

Stay calm and tell the operator which service you need (say ‘ambulance’ for a medical emergency). Then give the exact location or address, explain what has happened, and describe the casualty’s condition — for example whether they are conscious and breathing. Useful sentences include, ‘I need an ambulance,’ ‘There has been an accident,’ and ‘He is not breathing.’ Do not hang up until the operator tells you to.

Practise by: (1) Grouping words by theme — people, injuries, symptoms, kit and treatment — so they are easier to remember. (2) Writing example sentences such as ‘Apply pressure to stop the bleeding.’ (3) Labelling the items in a real first-aid kit with their English names. (4) Role-playing a 999 call with a partner. (5) Using LexFizz’s Flash Cards and Quiz games to review the key terms with instant feedback.
