This course gives you the knowledge to help a colleague who is injured or suddenly becomes ill at work, whether you are new to first aid or refreshing what you already know. You will learn how to manage medical emergencies, how to act with confidence, and when to call for professional help.

Please note: this online course gives you the theory of first aid. It does not replace certified practical first aid training. To become a qualified first-aider at work, you must complete an appropriate practical Emergency First Aid at Work or First Aid at Work course with a competent training provider; an accepted blended-learning course may combine online theory with face-to-face practical teaching and assessment.

By the end of this course, you will be able to:

• Describe the first aid duties of employers under the Health and Safety (First-Aid) Regulations 1981.
• Carry out a primary and a secondary survey of a casualty.
• Give CPR, use a defibrillator, and place a casualty in the recovery position.
• Deal with choking, wounds, bleeding, shock, burns, eye and head injuries, fractures and spinal injuries.
• Help someone with asthma, anaphylaxis, diabetes, epilepsy, a heart attack or a stroke.
• Deal with fainting, hyperventilation, nosebleeds, sprains, poisoning and drowning.
• Record and report incidents correctly.

First aid is the immediate help given to someone who is injured or ill, until professional medical help arrives or the person recovers. It has three aims:

• To preserve life.
• To prevent the condition from getting worse.
• To promote recovery.

Everything you learn in this course serves these three aims. First aid also means protecting yourself: a first-aider who becomes a second casualty cannot help anyone.

The Health and Safety Executive, or HSE, publishes statistics on work-related injury and ill health in Great Britain every year. Its recent figures show that:

• 126 workers were killed in accidents at work in 2025 to 2026.
• In 2024 to 2025, an estimated 680,000 workers suffered a non-fatal injury at work.
• In the same year, about 1.9 million workers suffered from work-related ill health.

Quick, correct first aid can make the difference between life and death, and between a short and a long recovery.

The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate and appropriate equipment, facilities and people, so that employees can be given immediate help if they are injured or taken ill at work.

What is adequate and appropriate depends on the workplace, so the employer must carry out a first aid needs assessment. The minimum for any workplace is:

• A suitably stocked first aid kit.
• An appointed person to take charge of the first aid arrangements.
• Information for employees about the first aid arrangements.

The needs assessment looks at the hazards, the number of employees, the layout of the site, shift and lone working, the distance to the nearest emergency department, and whether members of the public are present.

In a small, low-risk office, a first aid kit and an appointed person may be enough. Higher-risk workplaces, such as construction sites, need trained first-aiders, often several. Everyone must know how to summon help and who to contact, on every shift.

There is no fixed legal list. The contents should be based on your needs assessment, following HSE guidance. A typical kit includes:

• Sterile dressings, plasters and wound dressings in different sizes.
• Roller and triangular bandages.
• Disposable nitrile gloves.
• A face shield or pocket mask for rescue breaths.
• Alcohol-free cleansing wipes and gauze pads.
• Adhesive tape, safety pins, scissors and tweezers.
• Burn dressings, or cling film for covering burns.

Check the kit regularly, and replace anything used or out of date.

When you find someone who is injured or unwell, first look for anything that could kill them in the next few minutes. This quick check is called the primary survey.

Use the letters D R A B to remember the four steps, always in this order:

• Danger.
• Response.
• Airway.
• Breathing.

Each step is explained on the following slides.

Before you go near the casualty, check that it is safe for you, for them and for anyone else nearby. Look for traffic, electricity, chemicals, fire, falling objects or broken glass.

If there is a danger, make the area safe if you can, for example by switching off the power. If you cannot, keep back and wait for the emergency services. Never put yourself at risk.

If in doubt, call 999 straight away. The European emergency number, 112, also works in the United Kingdom and reaches the same services.

Next, check whether the casualty responds. Kneel beside them and speak loudly and clearly: ask, "Can you hear me?" or "Open your eyes."

If they do not respond to your voice, gently tap or shake their shoulders. Never shake them roughly, because they may have a neck or spinal injury.

If they answer, move or open their eyes, they are responsive. If there is no response, shout for help, but stay with the casualty and move on to the airway.

An unresponsive casualty can easily lose their airway, because the tongue can fall back and block the throat. To open the airway:

• Place one hand on their forehead, and gently tilt the head back.
• Place two fingertips under the point of the chin, and lift the chin.
• Look in the mouth, and remove anything obvious only if you can do it easily.

If the casualty is responsive, check that they can speak and breathe freely.

Keep the airway open, and check for normal breathing for no more than 10 seconds. Look for the chest rising and falling, and listen for breath sounds.

• If they are breathing normally, but are unresponsive, place them in the recovery position, which is covered in the next module.
• If they are not breathing, or not breathing normally, call 999 or 112 for an ambulance straight away, and start CPR.

Occasional gasps are not normal breathing. Treat them as a sign of cardiac arrest.

If you can, send a helper to call, and to bring a defibrillator. If you are alone, use the speaker on your phone so that you can stay with the casualty.

Stay calm and tell the call-taker:

• Exactly where you are, including the postcode if you know it.
• What has happened, and how many people are hurt.
• The casualty’s condition, especially whether they are breathing.

Do not hang up until the call-taker tells you to. Ask someone to meet the ambulance and guide the crew in.

You find a colleague lying unconscious and bleeding in the staff car park. Work through the steps in order:

• Danger: check for moving vehicles, and ask a colleague to stop the traffic.
• Response: speak loudly, then gently tap the shoulders. There is no response.
• Airway: open the airway with a head tilt and chin lift, taking care with the neck.
• Breathing: check for up to 10 seconds. If they are not breathing normally, call 999 or 112, or send someone to call, and start CPR.

If they are breathing normally, move on to the secondary survey.
